Frontline Medical News
CHICAGO – Successful
management of infected
aortic endovascular grafts
requires careful operative
planning and execution, meticulous postoperative care,
and a fair bit of creativity,
according to Dr. Thomas C.
Bower, chair of vascular and
endovascular surgery at Mayo
Clinic, Rochester, Minn. “I’ve
found the operations to be
more challenging and more
difcult than explanting portions or total graft excision
when the infection has occurred in a hand-sewn graft.”
Unlike the typical bimodal
distribution seen with handsewn graft infections, infec-
tion following endovascular
repair of aortic aneurysms occurs from days up to 3 years
after surgery. “These infections are uncommon, but we
are seeing more of them,” he
said at a symposium on vascular surgery sponsored by
Northwestern University.
Roughly two-thirds of
patients will present with
fever, nonspecifc abdominal or back pain, malaise,
weight loss, or night sweats.
If time permits, preoperative
assessments include echocardiography for left ventricular
function, arterial blood gases
for pulmonary function since
many patients are smokers,
and renal ultrasound if creatinine is ≥1.5 mg/dL after

Frontline Medical News
LAKE BUENA VISTA,
FLA. – Academic surgeons earn an average of
10% or $1.3 million less in
gross income across their
lifetime than surgeons in
private practice, an analysis
shows.
Some surgical specialties
fare better than others,
with academic neurosurgeons having the largest
reduction in gross income
at $4.2 million (–24.2%),
while academic pediatric
surgeons earn $238,376
more (1.53%) than their
private practice counterparts. They were the only
ones to do so.
Several academic surgical
specialties did not make
the 10% average, including
trauma surgeons whose
lifetime earnings were
down 12% or $2.4 million,
vascular surgeons at 13.8%
or $1.7 million, and surgical
oncologists at 12.2% or $1.3

Indications
The Valiant® Thoracic Stent Graft with the Captivia® Delivery System is
intended for the endovascular repair of all lesions of the descending
thoracic aorta (DTA) in patients having appropriate anatomy, including:
• iliac/femoral access vessel morphology that is compatible with vascular
access techniques, devices, and/or accessories;
• nonaneurysmal aortic diameter in the range of 18 mm to 42mm (fusiform
and saccular aneurysms/penetrating ulcers), 18 mm to 44 mm (blunt
traumatic aortic injuries), or 20 mm to 44 mm (dissections); and
• nonaneurysmal aortic proximal and distal neck lengths ≥ 20mm (fusiform
and saccular aneurysms/penetrating ulcers), landing zone ≥20 mm proximal
to the primary entry tear (blunt traumatic aortic injuries, dissections).
The proximal extent of the landing zone must not be dissected.
Contraindications
The Valiant Thoracic Stent Graft with the Captivia Delivery System is
contraindicated in:
• Patients who have a condition that threatens to infect the graft.
• Patients with known sensitivities or allergies to the device materials.
Warnings and Precautions
The long-term safety and efectiveness of the Valiant Thoracic Stent Graft with
the Captivia Delivery System has not been established. All patients should be
advised that endovascular treatment requires lifelong, regular follow-up to
assess the integrity and performance of the implanted endovascular stent
graft. Patients with specifc clinical fndings (for example, enlarging aneurysm,
endoleaks, migration, inadequate seal zone, or continued fow into the false
lumen in the case of a dissection) should receive enhanced follow-up. Specifc
follow-up guidelines are described in the Instructions for Use. The Valiant
true that there is no oversight or
ombudsman to protect the patient
in these outpatient facilities. Hospital-employed or university vascular
surgeons may correctly imply that
there is more oversight of procedures
performed in hospital facilities and
that this should limit unnecessary
procedures. Needless to say, that is
not the case in all institutions.
In our 600-bed municipal hospital,
there is limited peer review and the
few times when it has been applied
it has, on occasion, resulted in legal
suits against the reviewing medical
staf. Additionally, institutions that
reward practitioners based on relative value units may also induce a
perverse incentive to overuse procedures.
As Dr. Lawrence describes in
his article, site of service may not
be the only driving force behind
unnecessary interventions. In fact
the Clinical Council of the SVS has
seized upon appropriate care in offce-based centers and is working on
constructive suggestions to ensure
not only that site of service is convenient for patients, but also that it
provides appropriate high quality
care. For the time being the SVS
recognizes that we need improved
oversight and peer review in these
physician-owned centers, and that
Thoracic Stent Graft with the Captivia Delivery System is not recommended
in patients who cannot undergo, or who will not be compliant with, the
necessary preoperative and postoperative imaging and implantation
procedures as described in the Instructions for Use. Strict adherence to the
Valiant Thoracic Stent Graft sizing guidelines as described in the Instructions
for Use is expected when selecting the device size. Sizing outside of this range
can potentially result in endoleak, fracture, migration, infolding, or graft wear.
As cautioned in the Instructions for Use, a balloon should never be used when
treating a dissection. The safety and efectiveness of the Valiant Thoracic Stent
Graft with the Captivia Delivery System has not been evaluated in some
patient populations. Please refer to the product Instructions for Use for details.
MRI Safety and Compatibility
Non-clinical testing has demonstrated that the Valiant Thoracic Stent Graft is
MR Conditional. It can be scanned safely in both 1.5T and 3.0T MR systems
under specifc conditions as described in the product Instructions for Use.
For additional information regarding MRI please refer to the product
Instructions for Use.
Adverse Events
Potential adverse events include, but are not limited to access failure,
access site complications (e.g. spasm, trauma, bleeding, rupture, dissection),
adynamic ileus, allergic reaction (to contrast, antiplatelet therapy, stent
graft material), amputation, anaesthetic complications, aortic expansion
(e.g. aneurysm, false lumen), aneurysm rupture, angina, arrhythmia, arterial
stenosis, atelectasis, blindness, bowel ischemia/infarction, bowel necrosis,
bowel obstruction, branch vessel occlusion, buttock claudication, cardiac
tamponade, catheter breakage, cerebrovascular accident (CVA) / stroke,
change in mental status, coagulopathy, congestive heart failure, contrast
we should not simply abandon them
because of the abusive behavior of a
few unethical practitioners.
The New York Times article and
Dr. Lawrence’s article and letter to
the New York Times struck a chord
with our membership. It has provoked an outpouring of comments
and suggestions from our membership. Some of these are to be found
in this edition as letters to the editor.
It is apparent that many of us are
horrifed by what we are seeing, not
only in outpatient facilities but also in
hospitals.
I believe this is such an important
issue that I have requested our associate editors to write a brief comment on their views on the matter
and to specifcally identify methods
of rectifying the current overuse of
vascular procedures (see the following 2 pages).
I am hopeful that the NY Times
article and the responses we publish
will instigate vascular surgeons to
stand up for our profession and the
well-being of our patients. For if we
do not, we will continue to be marginalized by newspaper reporters
and government agencies. They will
continue to lump us together with
interventionalists who may not follow the same ethical road that most
of us travel.

FROM THE EDITORS
The associate editors weigh in
Editor’s Note: The associate editors of Vascular
Specialist were asked to provide their perspectives on
the stenting controversy. Here is a selection.
Dr. Frank J. Veith: The recent lead
article in the New York Times on
excessive implantation of lower
extremity stents highlights one key
point. Vascular
surgeons and all
vascular specialists who treat
lower extremity
occlusive disease
should always
clearly inform
patients with
intermittent
DR. VEITH
claudication that
one acceptable
treatment option is medical and
lipid-lowering therapy without any
invasive treatment of their arterial
blockage. They should be informed
that the condition almost never
leads to limb loss and that invasive
treatment can safely be delayed until such progression occurs. Given
such honest reassurance and the
option to choose their treatment,
most patients with claudication will
choose a conservative rather than an
invasive approach, and unnecessary
stent/angioplasty and other lower
extremity interventional procedures,
as described in the Times article,
will be minimized.
Dr. John F. Eidt: The truth is we all
bear responsibility. The treatment of
lower extremity peripheral artery disease (PAD) has largely defed prior efforts to defne appropriate care. Even
the SVS document recommending
risk factor modifcation in the initial
management
of intermittent
claudication
leaves substantial room for
individualized
judgment. The
appropriateness
of intervention is
largely in the eye

of the beholder.
“Lifestyle-limiting” claudication can be invoked as
justifcation for intervention in virtually anyone. But I do believe that
vascular surgeons are more wary of
the adverse consequences of vascular intervention for one important
reason – we do amputations. We are
unique among vascular specialists in
that we deal with the tragedies of
unwarranted vascular procedures.
For vascular surgeons, failure of intervention means more than binary

revascularization. Performing an amputation after failed intervention in

a claudicant leaves an indelible mark
on each of us and may underlie our
inherently conservative approach
to PAD. But we need to be fearless
in speaking the truth and serving
as advocates for exemplary patient
care. Continuing a relationship with
a source of carotid and aortic referrals while turning a blind eye to
meddlesome lower extremity intervention sends the wrong message.
Our silence constitutes tacit approval.
Too frequently I hear a patient say
“my cardiologist says there is nothing else he can do, go see a vascular
surgeon.” Despite years of branding
eforts by the SVS, surveys of primary care providers and the public alike
confrm that many remain uncertain
of our skills. We need to do a better
job of spreading the word that vascular surgeons are “leaders in the minimally invasive treatment of PAD.”
Not the last resort.
Dr. Frank Pomposelli: I could not

with claudicants since they are most
likely to have the least complex disease – match made in heaven or hell,
depending on your perspective. One
cardiologist quoted in the N.Y. Times
piece said patients with claudication
have been “grossly under treated” – a
convenient posture to take when billing Medicare $4.5 million a year. The
other cardiologist who was the focus
of the investigation called the charges
“baseless and fction” and stated his
center had the lowest rate of amputation in the country. It gets back to
Dr. Eidt’s point how it’s easy for the
nonsurgeon to dismiss amputation as
an occasional unfortunate byproduct
of a busy practice when you never
have had to tell a patient they need
one and sufer with them through the
emotional and physical trauma that
always follows. I was taught like many
of you, I suspect, that any amputation
after treatment for claudication should
be considered not only an unacceptable complication but also a failure of
the trust the patient placed in me. My
mentor was a militant nihilist when it
came to surgery for claudication but
that concept is always in my mind
whenever I treat a patient and has always tempered my decision making.
I like to think our recently published
practice guidelines will help but am
skeptical that it will make a positive
impact where it is most needed; on
those who are primarily driven by fnancial gain. I’d also point out that Dr.

the most infuential transaction
occurs in the exam room when we
are face to face with our patients. Remember, even though we are a small
group, we can have great infuence
when we always, always, always do
what we know is right.
Dr. Alan M. Dietzek: Dear Patient,
Let me introduce myself. I am a
Board-Certifed
Vascular Surgeon. My specialty is unique
in that I am well
versed and formally trained in
both the medical and surgical
management
DR. DIETZEK
of peripheral
vascular disease.
No other specialist can make this
claim. Most often, vascular problems
can be managed conservatively with
a combination of risk factor and
lifestyle modifcation, and occasionally prescription medications, all of
which I can outline and or prescribe
for you. When necessary, however,
I am prepared to treat your vascular
problem with either a minimally
invasive procedure or open surgery
depending on which treatment will
provide you with the best outcomes.
Again, only a vascular surgeon is
capable of ofering you these treatment options. I am dedicated to your
well-being. I am a Board-Certifed
Vascular Surgeon.
Dr. Murray L. Shames: The recent
New York Times article, “Medicare
payments surge for stents to unblock
blood vessels in limbs,” brings up
a critical issue in how we train our
residents to think and practice in the
future. Our current generation of
residents is faced with a tremendous
fnancial burden of medical school
debt, and they are being ofered highly competitive salaries after gradua-
tion. The motivation to join groups
with outpatient vascular centers is
certainly attractive: Why not have autonomy from the
hospital, control
your work environment, and increase efciency.
As educators we
must continue to
use clinical evidence and societal guidelines
DR. SHAMES
( J. Vasc. Surg.
2015:1-40) to
guide our clinical practice.
As vascular surgeons we have been
trained to manage asymptomatic
PAD and intermittent claudication
nonoperatively due to it’s relatively
benign natural history; endovascular interventions have dramatically
increased the treatment of claudication, even in our own hands. We
must continue to teach our residents
restraint and to consider the impact
of the interventions we perform.
That way we can maintain our status as the leaders in vascular disease
management and not just “interventionalists” that treat lesions.
Dr. Joann Lohr: The presence of
a stenotic lesion does not mandate
treatment either with a stent or surgical intervention but needs critical
assessment of
the impact on
the patient’s
quality of life.
Risk factor modifcation needs to
be undertaken
before any intervention and

comes and durability of repairs.
The only outcome that matters is the
patient’s. “How does treatment of
this lesion change my lifestyle?” is a
question that needs to be answered
for each patient. Treating physicians
need to establish long-term relationships. Never be afraid to tell patients
a procedure is not the frst line of
treatment. Thoughtful application of
new technology is needed in all areas
of medicine. Just because we can,
should we? Appropriate individualized treatment plans and goals need
to be established for each patient we
treat.
Dr. Larry Kraiss: Vascular surgeons
provide the full spectrum of care
for PAD from medical management
through intervention to the unfortunate situations when amputation
is necessary. The more sobering of
these experiences have imbued most
of us with a healthy respect for how
an intervention can go wrong. If
you haven’t had
to explain to a
patient or family
why an amputation is necessary,
you probably
don’t have the
same concern.
Thus, many of
us have a very
DR. KRAISS
conservative approach to PAD
intervention; primum non nocere is
the governing principle. This principle is supposed to guide the actions
of all physicians but I can’t help but
wonder if something happened to
primum non nocere on the way to
the outpatient endovascular center.
When physicians become fnancial
stakeholders in these enterprises, a
pernicious incentive is introduced
that is almost impossible to exclude
from daily clinical decision making.
Hospital-based physicians are also
subject to temptation to perform
unnecessary yet lucrative procedures
but at least these are being done
more in the open. I suspect that the
development of these centers has
allowed much activity to occur that
would rightly be condemned under
the scrutiny of one’s hospital peers.
Dr. Laura Drudi: It really comes
down to adequately informing the
patient. I always fnd it astounding
how many patients I encounter
asking me in a timid tone, “What
exactly did I have done on my leg?”
I question what patients actually
understand and
retain after being
overwhelmed
by the informed
consent we
have prior to an
intervention. I
see frst hand
the catastrophic
failures of interDR. DRUDI
vening on severe
claudication
leading to limb loss and worsening
of quality of life. It’s disheartening to
see adverse outcomes following vascular interventions either by vascular
surgeons or other interventionalists,
but I believe that if you are performing an intervention you should have
the expertise and technical skills to
deal with the complications.
The best interventionalists know
when not to intervene and that
should be the mantra we live by. We
should be advocates for our patients
at a local institutional level as well as
a public level. I believe that following
the New York Times article the pub-
5
lic will be more aware of the potential for inappropriate or unnecessary
interventions, many of which are
being performed by specialists other
than vascular surgeons.
The Society and individual vascular
surgeons should capitalize on this
opportunity to educate patients as to
the benefts of consulting with a vascular surgeon before undertaking any
endovascular procedure.
Dr. Elliot L. Chaikof: Both government and private payers have a vested interest in ensuring that patients
receive the highest quality care, while
reducing the unsustainable rate of
increase in health
care costs. In
Massachusetts
and elsewhere
in the United
States, this has
led to the introduction of new
risk contracting
models that feaDR. CHAIKOF
tures a global
payment with
incentives linked to efciency and
quality.
At our institution, approximately
60% of patients are now in such risk
contracts. Primary care physicians are

espite the unfortunate press,
we as a more global medical
vascular community are unable
to police our own. I have been involved in two specific instances in
which inappropriate and overuse
of endovascular therapy has been
addressed. Unfortunately, these
practitioners continue to perform
unindicated procedures while hospitals and state medical boards refuse to act.
What is Medicare to do when our
own medical regulatory bodies fail
to act on behalf of patients and the
payor? The two routes of targeting
practitioners through Medicare high
outliers and legal recourse for poor
outcome in unindicated procedures
will remain until our societies (this
includes SVIR and ACC) decide to
collaborate and ensure appropriate

We need the SVS to be a major

We need to silence the naysayers
and the media hogs by developing
a method so that surgeons who
care for vascular patients in an offce-based vascular suite are certifed
by the Society in the form a Center
of Excellence designation. Initial
certifcation would be followed by
ongoing proactive reviews on a serial
basis.
I would ask that the leaders of our

This is based on an understanding

is indicated for symptom relief.
With new minimally invasive techniques available and specialists other

with claudication do not beneft from

In CORAL, the initial hypertension inclusion criterion of 155 mm
Hg was subsequently abandoned
during the trial, suggesting that
hypertension in many of these
patients may have been mild and/
or well controlled. Although medical therapy in CORAL was standardized, it also is notable that all
patients had their medical therapy
adjusted prior to randomization
during a roll-in phase to achieve
target blood pressure goals of
130/80 in patients with CKD and/
or diabetes or 140/90 otherwise.
I would suggest that achievement
of these blood pressure targets on

amlodipine-atorvastatin) might be
appropriately considered success of
medical therapy for patients with
hypertension in the absence of
renal dysfunction, making it challenging to defend proceeding with
revascularization in this scenario.
The study protocol, although
well designed from the perspective of attempting to isolate the
efect of renal artery angioplasty
and stenting, therefore did not
uniformly refect what would be
considered responsible utilization
of renal revascularization in a
real-world environment.
Patient enrollment in CORAL
was also very selective; only 947

The history of evolution and
evaluation of the role of renal
revascularization is remarkably
similar to that of renal denervation, initially and with considerable conviction thought to be a
cure for hypertension. However,
when properly assessed by prospective randomized comparison,
there was found to be absolutely no
beneft.
So, given the considerable objective
evidence from two major trials and
revisiting the basics of the pathophysiology of atherosclerotic renovascular disease, to expect beneft from

aside, however, CORAL does
provide some very useful observations that should inform treatment
decisions. The results demonstrate
the efcacy of contemporary medical therapy for many patients, and
show that revascularization ofers
no additional beneft when medical therapy achieves an acceptable
clinical response (defned by stable
renal function and reasonable
blood pressure control). Additional
subgroup analyses of the CORAL
data are anticipated, but will likely
be underpowered to draw conclusions in the absence of identifed
revascularization efects.
So when should revascularization be considered for patients
with atherosclerotic renal artery
stenosis? In general, medical therapy is adequate for most patients
and should be implemented prior
to any consideration of procedural
intervention. Revascularization
should be considered only for patients who have failed appropriate,
aggressive medical therapy; the
medications used in CORAL can
certainly be regarded as adequate
initial therapy for symptomatic
renal artery stenosis, but many
providers (including myself )
would argue that additional agents
should be considered before proceeding with revascularization.
When decline in renal function
is the indication for considering
revascularization, alternative
causes (such as intrinsic renal disease) should diminish enthusiasm
for proceeding with angioplasty
and stenting, particularly when
the anatomic disease distribution
does not afect the entire renal
mass (as in patients with two
kidneys and unilateral stenosis).
Appropriate candidates for revascularization include patients with
severely impaired renal function
(particularly in the setting of a
precipitous functional decline) or
severe acute blood pressure ele-
vation associated with hypertensive
emergency (such as acute congestive
heart failure, encephalopathy, acute
coronary syndrome, or other signs
and symptoms of target organ damage resulting from hypertension and/
or volume overload). Continuation
of failed medical therapy is often
unacceptable to these “no-options”
patients as well as their providers,
both of whom presumably would be
unlikely to accept randomization to
ongoing medical management.
Other populations that are not represented within these trials include
patients with renal artery restenosis
and those with nonatherosclerotic
disease; it is therefore important to
exercise caution when generalizing
these study results to these distinct
groups of patients. Enrolling pa-
tients with severe symptoms who
have failed medical therapy will
likely remain challenging for future
randomized studies in the absence
of alternative treatment options.
Although the benefts of renal angioplasty and stenting for these
“no-options” patients remain to be
proved, the uncertainty of response
to revascularization is often easier to
accept than the ongoing morbidity
and mortality associated with staying
the course when medical therapy has
failed.

but they are also struggling with increasing student loan debt and longer
training as more surgical residents
elect to enter fellowship rather than
general practice.
This growing fnancial liability
coupled with declining physician
reimbursement could rapidly shift
physician practices and thus threaten
the fscal viability of certain surgical
felds or academic surgical careers.
“The more fnancially irresponsible
you make it to become an academic
surgeon, the more we put at risk our
current mode of training,” Dr. Lopez
of Wake Forest University in Winston-Salem, N.C., said.
To account for additional factors
outside gross income, the investigators ran the numbers using a second
analysis, a net present value calculation, however, and came up with
roughly the same salary gap to contend with.
Net present value (NPV) calculations are commonly used in business
to calculate the proftability of an
investment and also have been used
in the medical feld to gauge return
on investment for various careers.
The NPV calculation accounts for
positive and negative cash fows over
the entire length of a career, using
in this case, a 5% discount rate and
adjusting for infation, Dr. Lopez
explained.
Both the lifetime gross income and
5% NPV calculation used data from
the Medical Group Management
Association’s 2012 physician salary report, the 2012 Association of American Medical Colleges physician salary
report, and the AAMC database for
residency and fellow salary.
The NPV assumed a career length
of 37-39 years, based on a retirement
age of 65 years for all specialties.
Positive cash fows included annual
salary less federal income tax. Negative cash fows included the average
principal for student loans, according
to the AAMC, and interest at 5%, the
average for the three largest student
loan lenders in 2014, he said. Student
loan repayment was calculated for
a fxed-rate loan to be paid over 25
years beginning after residency or
any required fellowship.
The average reduction in 5% NPV
across surgical specialties for an academic surgeon versus a privately
employed surgeon was 12.8% or
$246,499, Dr. Lopez said.
Once again, academic neurosurgeons had the largest reduction in 5%
NPV at 25.5% or a loss of $619,681,
followed closely by trauma surgeons
(23% or $381,179) and surgical oncologists (16.3% or $256,373). Academic
pediatric surgeons had the smallest
reduction in 5% NPV at 4.2% or
$88,827.

an academic setting.
Dr. Lopez countered that, increasingly, even private surgeons are no
longer truly private surgeons.
“More and more surgical groups
are being bought up by hospitals, and
even the private surgical groups are
being bought up by hospitals, which
does stabilize your income to some
extent,” he said.
“We all still have [relative value
unit] goals to meet and RVU incentives that make it so you can get paid
a little more, but it’s something that’s
a consideration. It is a risk-reward
to be a private surgeon. Depending
on how your contract is structured
or how your group decides to pay
the partners, it may be that if you
don’t take very much call or take
that many cases, you’ll end up on the

Dr. Lopez agreed, citing how the
increasing number of stent placements by cardiologists, for example,
has impacted the bottom line of
cardiothoracic surgeons. The NPV
calculation was specifcally used,
however, because it gets at market
forces such as infation and return on
investment, not addressed by gross

Lifestyle choice important
T
he basic fnding of the disparity
is in fact true leaving aside the
fawed methodology of too many
assumptions by including all academic ranks, practitioners of diferent durations in practice, diference
in benefts, tuition assistance, and
assuming student loans for all surgeons plus a risk free rate that is
too high.
Our analysis of both vascular
and general surgeon compensation points to a larger disparity at
junior academic ranks over the
last decade. With our own studies
showing a shortage of vascular sur-
geons, retention of practitioners is
paramount for all health systems.
Academic centers rely on faculty
giving up a percentage of their
compensation for the pleasure of
teaching, research and intellectual
stimulation. The unanswered question is: How much of a disparity
will junior academic surgeons
tolerate, and how do they value
lifestyle against additional compensation? Time will tell.

able Care Act. Quite honestly, for a
number of reasons and in large part
due to these changes, I believe the
lines of demarcation between private and academic practice are increasingly blurring. The pressures,
external threats, and challenges to
achieving a satisfying and economically viable practice are quite similar today irrespective of practice
type or location.
The increasing movement to
full-time hospital employment,
the increasing emphasis on quality
outcomes, impending changes in
reimbursement models, and the emergence of Accountable Care Organizations (ACOs) are factors afecting the
practices of all vascular surgeons. I
therefore believed that this was a most
appropriate topic to address at the
2015 Crawford Critical Issues Symposium. “How You Can Succeed Under
the Afordable Care Act” will provide
strategies that our members can follow to not only survive but thrive in
this new health care order.
VS: What takeaways do you hope
attendees will have at the end of
the session?
Dr. Perler: We will be bringing together in one forum a world class
group of nationally recognized experts and stakeholders in health care
to share their knowledge about, and
expectations for, the immediate and
mid-term future of health care economics. The panel includes individuals with diverse backgrounds and
interests including the perspectives

and economically viable
practice are quite similar.
of the employer, the payor, public
health policy-makers, and the practicing institution-employed vascular
surgeon. We believe these presentations and the opportunity for our
attendees to engage these leaders in
a question-and-answer session will
provide education about the expectations these stakeholders have of
clinicians and therefore allow our
members to develop strategies that
they might incorporate in their own
practices to continue professionally
satisfying and economically productive practices.
While all medical practitioners are
afected by these changes inherent in
the Afordable Care Act, because of
our relatively small numbers and the
increasing multispecialty completion
that vascular surgeons face, including
for many participation in multispecialty cardiovascular centers as well
as increasing hospital employment, I
believe that these issues are particularly relevant to our specialty.
VS: You have an interesting line-up
of panelists, what were your reasons for selecting each?
Dr. Perler: There are clearly multiple stakeholders or components in
our health care system with unique
backgrounds, interests, and agendas.
Each of them will bring to the Crawford Symposium a perspective from
his specifc component of the system,
the insurer, the employer, the hospital-employed surgeon, and someone
with specifc expertise in Accountable
Care Organizations and knowledge
of vascular surgical practice.
It was my expectation to bring
these experts together in one setting
to not only provide useful information for our attendees, but to allow
them to engage in a collective discourse that should provide an unparalleled educational experience for our
attendees.

VS: Where do you think their biggest
areas of agreement, and of disagreement, will be during the discussion?
Dr. Perler: That’s a great question and the short answer is I can’t
precisely predict. In general, I
would assume that there will be a
consensus that rising health care
costs must come under control and
physician reimbursement in the
future will be increasingly linked to
quality outcomes rather than pure
case volume. There also may be a
consensus on the importance of
longitudinal patient care.
Beyond the obvious, however, the
key question is whether or how the
health care system will align reimbursement to the distinctive competencies of vascular surgeons as the
only truly comprehensive vascular
specialists who provide the totality
of care including diagnosis as well as
medical, surgical, and endovascular
therapy. Will employers and insurers
recognize the value of the comprehensive care that only vascular surgeons provide? Will ACOs factor that
competency into specialty referral
patterns?
Further, will payors and hospitals
recognize the unique leadership that
vascular surgeons can provide in the
care of cardiovascular patients in the
hospital environment?

Study: Surgery offers chance
to adjust vascular medications
P
atients who are treated at sites
with longer participation in the
VQI had better medical management and this was associated with
higher survival rates, according to a
new study reported
in the April 2015
issue of The Journal
of Vascular Surgery.
Further, surgery
at a VQI site may relate to optimized
medications with the goal to improve
survival rates.
Led by Dr. Randall R. De Martino,
a team of researchers studied medical
management for vascular surgery patients at sites participating in the Vascular Quality Initiative and associated
patient survival rates.
Two key outcomes were noted: Site
participation in VQI is associated with
improved use of antiplatelets and statin medication for that site’s patients
undergoing vascular procedures; and,
treatment with AP and statins is associated with a 14 percent survival
advantage for patients at fve years
postsurgery.
“Medical therapy for patients with
vascular disease remains important
for their long-term prevention of
cardiovascular events,” noted Dr. De
Martino. “The surgical encounter
provides an excellent opportunity to
ensure that appropriate medications are
prescribed. As our
data demonstrate,
many patients remain medically undertreated and this
is associated with worse long-term
survival. Importantly, participating in
a quality improvement initiative, like
the VQI, is associated with improvements in medical management. This
highlights how we can use a quality
improvement collaborative to improve care for our patients.”
Since up to 75 percent of patients
with peripheral arterial disease will
ultimately die of cardiovascular causes,
it seems that medical management is a
strong tool to ensure patient survival.

Managing infection

rehydration. These tests are important because preoperative chronic obstructive pulmonary disease and renal
dysfunction correlate with worse
postoperative outcomes, he said.
Computed tomography angiography (CTA) is the most important
step of preoperative preparation,
with the sine qua non of infection
being air around the graft.
Unlike hand-sewn grafts where
infections can be localized, typically
there is total graft involvement in
these cases because the device is
left inside the aneurysm sac. Aneurysms or pseudoaneurysms also
have been seen above the infected
device, including at the top end of
suprarenal stents.
“This clearly has an impact on how
we approach patients, but what’s become very apparent to me is that CTA
often underestimates the amount of
periaortic infammation, especially at
the juxta- and pararenal locations.”
The Mayo group initially used
in situ antibiotic-soaked prosthetic
grafts for explanting EVAR devices,
which yielded “acceptable mortality
and reinfection rates, but primarily
outstanding patency rates.” However,
cryopreserved aortoiliac grafts have
now become their frst choice, he said.
An ABO match is not imperative, preparation takes roughly 45
minutes, branch closures done in
the lab are buttressed with sutures,
and the graft is turned over to
keep the lumbar arteries anterior,
which offers an easy fix if there is
bleeding, rather than having it on
the posterior wall. Cryopreserved
grafts, however, can dilate 40% and
lengthen 10% under pressure. “I’ve
been burned more than once where
the graft elongates more than I think,
and I end up having to cut a small
piece out to foreshorten it,” he said.
Surgeons should have several plans
for reconstruction, including routing a graft through a remote path,
remembering that CTA will underestimate the amount of periaortic
infammation. Separate bypasses of
the renal or visceral arteries are performed frst before the aortic clamp
is applied to reduce physiologic
stress. This requires knowledge of
the supraceliac and pararenal aorta
exposures, which really begins with
the correct choice of incisions, Dr.
Bower said. This is based on the aortic segment to be treated, position of
the new graft, the aortic clamp site,
and patient body habitus.
Most patients with EVAR infections
are approached with a midline ab-
dominal incision extended along the
xiphoid process, which is the linchpin for allowing upward and lateral
retraction of the abdominal wall, he
said. Choosing an incision that allows
a more vertical orientation to where
the new aortic anastomosis and
clamp site will be, rather than operating in a keyhole, is important.
The second step is to open up the
pararenal space by moving the viscera out of the way. This begins by
ligating the inferior mesenteric vein
and adjacent lymphatics, which allows incision of an avascular plane
along the base of the left transverse
colon. Retractor blades are set to
allow the upward and lateral retraction of the small bowel, the left
colon, and pancreas.
Exposure of the suprarenal or
supramesenteric aorta requires mobilization of the left renal vein after
ligation and division of its branches.
“If that vein is intensely involved
in infammation, don’t ligate the
branches in case you have to divide
that vein at the caval confuence.
Otherwise, you’ll run into some dysfunction of that left kidney.”
For a secure place for the aortic
cross clamp, the crura must be divided on either side of the diaphragm at
or above the supramesenteric aorta,
he added.
Key steps in total graft explantation
are to drain abscesses prior to surgery
to lower the bacterial burden and thus
reduce the postop infammatory response; bypass renal/visceral arteries
frst, if needed; remove the infected
graft; debride the aorta to healthy tissue; place the new graft and cover it
with omentum; and repair the bowel,
if needed. A piece of proximal aortic
wall should be sent to pathology to
ensure absence of bacteria or microabscesses. Organism-specifc antibiotics
are given intravenously for 6-8 weeks
followed by lifelong oral antibiotics.
An earlier report involving 24 patients with infected aortic endografts
showed potential contributors to
infection were endovascular reintervention in eight, aortoenteric fstula/
erosion in four, and various remote infections (J. Vasc. Surg. 2013;58:371-9).
Rifampin-soaked grafts were used in
15 patients, cryopreserved grafts in 4,
femoral vein in 2, and axillofemoral
grafts in 3. At 14 months follow-up,
patient survival, graft-related complications, and reinfection rates were
79%, 13%, and 4%, respectively.

he expert opinion from the
Northwestern Vascular Symposium regarding the management
of EVAR infections reminds us
of the importance of appropriate
patient selection, proper performance of the planned procedure,
and long-term follow-up. As EVAR
has become the treatment of
choice for more than 80% of patients with infrarenal AAAs in the
United States, the rate of patients
that return with EVAR
infections, although rare,
is increasing and their
management can be more
challenging than that of
a primary or aortic graft
infection as suggested by
Dr. Bower in this opinion.
The planning for these
cases is critical with multiple options for treatment currently
available and endorsed by a variety
of investigators. From an evaluation standpoint, CTA is critical for
diagnosis and case planning. Air
around the graft is considered the
“sine qua non” of infection but if
it presents in the frst month after
EVAR it can be due to trapped air
introduced into the sac during the
intervention.
Patients with air in the sac at the
initial postprocedure evaluation
should be considered for early follow-up to make sure this fnding
resolves. Further assessment that
will change the management of
the patient includes the type of
EVAR device, infra- or suprarenal,
since the entire removal of a suprarenal device usually requires
supraceliac cross-clamping with its
associated morbidity and mortality.
Drainage of the infected cavity, as
suggested by Dr. Bower, can help
lower the bacterial burden and
provide information regarding the
ofending organism. That information will help the vascular surgeon
decide if an in-line reconstruction
or an extra-anatomical one is more
appropriate in the patient’s situation, as more virulent organisms
tend to be associated with higher
reinfection and complication rates
when in-line reconstructions are
performed.
The diferent options for aortic
access need to be evaluated based
on the anatomy of the patient. A
transabdominal approach is best
for most patients as it allows access to the iliac arteries bilaterally
for removal of the entire graft,
debridement of the infected bed,
aortic and/or visceral reconstruc-
tion, and omental coverage of the
in-line graft or aortic stump if an
extra-anatomical reconstruction
is selected. The retroperitoneal
approach should be considered for
patients that will require extensive
perivisceral work, as may be necessary from suprarenal or fenestrated
devices, but limitations exist accessing the right iliac system and potentially intraabdominal targets for
visceral or renal reconstructions.
The best confguration to reconstruct these
patients remains largely
undetermined based on
the literature. The published experience from the
Mayo Clinic ( J. Vasc. Surg.
2013;58:371-9), in which
some of the opinions
of Dr. Bower are based,
suggested excellent results in 24
patients mostly treated with rifampin-soaked in-line reconstructions
with a periprocedural mortality of
4%. Cryopreserved aortic grafts
“have become the conduit of
choice for the group at this time,”
stated Dr. Bower, to try to further
decrease the reinfection rates in
their patient population. There are
limited data regarding the use of
cryopreserved aortoiliac segments
for aortic infections and less for
EVAR infections. The most recent
and largest series ( J. Vasc. Surg.
2014;59:669-74) included 220 patients with aortic infections with a
perioperative mortality of 9% and
cryopreserved graft complications
in another 12%-15% of patients.
In summary, aortic infections
associated with EVAR are challenging problems that should be
addressed in regional centers with
experience. Renal and visceral
reconstructions as well as supravisceral clamping are associated
with signifcantly higher periprocedural morbidity and mortality
based on the extensive experience
at the Cleveland Clinic with EVAR
explants ( J. Vasc. Surg. 2014;59:88693). The choice of the reconstruction and the material used should
be based on the ofending organism, type of EVAR device, extent
of the infectious process, and the
expertise of the treating physician.

NEWS FROM WASHINGTON
Transcarotid angioplasty
device approved
The Food and Drug Administration
has approved a minimally invasive
angioplasty system that enters the
carotid artery adjacent to a blockage, and captures embolic debris by
extracorporeal filtration of blood
near the blockage.
The ENROUTE Transcarotid Neuroprotection System (ENROUTE
TNS) is inserted into the artery near
the stenotic region. As the stent is
deployed, the system draws blood
down the tube and away from the
brain under high pressure. An extracorporeal flter traps any emboli,
and the fltered blood is returned via
the femoral vein.
ENROUTE TNS was approved
on the basis of the successful
ROADSTER trial (Safety and Efficacy Study for Reverse Flow Used
During Carotid Artery Stenting
Procedure).
In this study, there was a 3.5%
rate of stroke, heart attack, and
death among patients treated with
the device – significantly lower
than the study’s primary outcome
goal of 11%.
The rate of adverse events was
about 14%; these included excessive
bleeding or injury at the device
insertion site, hypotension, and
thrombosis.
The system’s benefits include its
minimally invasive approach and
the ability to successfully navigate
severe carotid tortuosity. It also
may be more successful than traditional arterial angioplasty for patients with difficult anatomy of the
aortic arch, according to an FDA
statement.
Manufactured by Silk Road,
Sunnyvale, Calif., the ENROUTE
TNS device was approved through
a 510(k) submission, which provides
an approval pathway for low- to
moderate-risk devices that are substantially equivalent to a legally
marketed device.
According to the FDA statement,
ENROUTE TNS is equivalent to a
currently marketed flow-reversal
system that uses similar technology and has the same intended use,
but is designed to be introduced
through the groin.

Adhesive for varicose veins
The VenaSeal closure system,
which uses an adhesive directly
injected into the vein, has been approved as a permanent treatment
for symptomatic, superficial vari-
cose veins, the Food and Drug Administration announced on
February 20.
“This new system is the first to
permanently treat varicose veins
by sealing them with an adhesive,”
Dr. William Maisel, acting director
of the Office of Device Evaluation
in the FDA’s Center for Devices
and Radiological Health, said in
the FDA’s statement. Because the
system “does not incorporate heat
application or cutting, the in-office procedure can allow patients
to quickly return to their normal
activities, with less bruising,” he
added.

The VenaSeal system differs from
other procedures used to treat varicose veins, which use drugs, lasers,
radiofrequency, or incisions, the
FDA statement points out.
The complete sterile kit includes
the adhesive (n-butyl-2-cyanoacrylate), which solidifies when injected
directly into the target vein via a
catheter, under ultrasound guidance.
The additional system compo-
MA R C H 2 0 1 5 • VA S C ULA R S P EC IA LIS T
nents include the catheter, the adhesive, a guidewire, dispenser gun,
dispenser tips, and syringes.
Approval was based
on data from three clinical trials sponsored by
the manufacturer. In the
U.S. study that compared
results in 108 patients
treated with the VenaSeal
system and 114 patients treated
with radiofrequency ablation therapy, the device was shown “to be
safe and effective for vein closure
for the treatment of symptomatic
superficial varicose veins of the
legs,” according to the
FDA.
In the study, adverse
events associated with the
VenaSeal treatment included phlebitis and paresthesias in the treated areas,
which are “generally associated with treatments of this condition,” the FDA statement noted.
The agency reviewed the VenaSeal
System as a class III medical device,
considered the highest risk type of
medical devices that are subjected
to the highest level of regulatory
control, and which must be approved
before marketing.
VenaSeal is manufactured by Covidien, which acquired Sapheon,
the company that developed VenaSeal, in 2014. The system has
already been approved in Canada,
Europe, and Hong Kong, according
to a Covidien statement issued last
year.

Forty Years of Innovation
Gore vascular devices address previously unmet
clinical challenges while maximizing patient outcomes.
Since 1975, engineers at W. L. Gore & Associates
(Gore) have worked closely alongside the world’s
leading physicians to develop and consistently improve upon a portfolio that answers the call of the
most demanding clinical challenges.
Putting patients frst, Gore’s versatile device
family elevates what is possible in therapy, now
afording minimally invasive treatment options to a
wider range of patients.
Longest Stent-Graft Available
The GORE® VIABAHN® Endoprosthesis is
the lowest profle, most fexible, self-expanding,
small-diameter endoprosthesis available. A result
of nearly two decades of continuing evolution, it
is the only stent-graft to receive approval for the
SFA (de novo, restenotic, and in-stent restenotic
disease), iliac artery, and arteriovenous access revision.
In October 2013, the GORE® VIABAHN®
Endoprosthesis became the longest stent-graft approved by the FDA, with a maximum length of 25
cm. The 25 cm endoprosthesis is designed to cover
long segment lesions in the SFA, reducing the need
for multiple devices. A multi-center European trial
supported the FDA’s approval of the 25 cm device.
Low Profle, Time-Proven Design
With more than 16 years and 190,000 devices distributed worldwide, the GORE® EXCLUDER®
AAA Endoprosthesis has elevated what is possible
in the treatment of abdominal aortic aneurysms
(AAAs), providing physicians with minimally invasive endovascular solutions for a wide range of
patient anatomies.
In 2014, Gore lowered the profle of the 23
mm and 26 mm trunk-ipsilateral leg devices and
the 23, 26, and 28.5 mm aortic extenders. The
profle reduction allows these ipsilateral legs and
aortic extenders to be used with a 16 Fr GORE®
DrySeal Sheath. No changes have been made to
the GORE® EXCLUDER® Device—instead, an
innovative process using ePTFE materials has been
used to constrain the device on the catheter. This
exemplifes Gore’s commitment to improving patient safety while maintaining ease-of-use for the
delivery of the GORE® EXCLUDER® Device.
Novel Solutions with Distinct Capabilities
Introduced in November 2013, the GORE® EXCLUDER® Iliac Branch Endoprosthesis is the frst
complete, fully engineered iliac system (iliac main
body device and internal iliac component) intended for endovascular treatment of common iliac
artery aneurysms or aortoiliac aneurysms.
The device—used in conjunction with GORE®
EXCLUDER® AAA Endoprosthesis components—
is built on Gore’s proven technology platform
and designed using the same durable, expanded
polytetrafuoroethylene (ePTFE) graft.
The GORE® EXCLUDER® Iliac Branch Endoprosthesis has CE mark and is in clinical study in the US:
Equipped for a Wider Range of Patient Anatomies
In September 2013, the Conformable GORE®
TAG® Thoracic Endoprosthesis received FDA approval for endovascular repair of acute and chronic
Type B dissections, making it the frst device to
receive FDA approval for this indication.
The Conformable GORE® TAG® Device ofers
conformability and ease of use, while accommodating tortuous and tapered anatomy. The device
resists compression and has a broad oversizing
window ranging from 6 to 33 percent. Physicians
are able to choose the appropriate oversizing for
the patient anatomy, which is particularly important in dissection patients due to the nature of the
disease.
As Gore continues to modify and add new treatment capabilities to its collection of devices, it
further demonstrates its commitment to providing
physicians with some of the most innovative devices available.

tion. The Endurant IIs Stent Graft System uses the
existing Endurant II delivery system allowing accurate placement and controlled deployment.2
The Endurant IIs Stent Graft System also
brings the unique benefit of expanding anatomical customization options.3 The system allows
physicians to utilize Medtronic’s full suite of
limb options on the patient’s ipsilateral and contralateral sides. Endurant IIs offers the ability
to have in-situ sizing on the ipsilateral side with
select limbs for adjustment during the case.3 Additionally, this new stent graft, Endurant IIs, provides up to a 20% reduction in distal diameter
compared to select Endurant II bifurs4 and may
provide simpler pre-case planning.3
Both the Endurant II and Endurant IIs systems
perform in a broad range of patients, including
those with short or angulated infrarenal aortic
necks, and those with tortuous iliacs. Physicians
can remain confdent in the clinical performance
of all of the Endurant® products, as evidenced in
