PC122 Causes and Treatment of Recurrent Symptoms After First Rib Resection for Thoracic Outlet Syndrome

June 1, 2017 - 00:00
Thoracic outlet syndrome (TOS) is a complex disease process with continued controversy regarding treatment and surgical approach. Understanding causes of treatment failure improves preoperative risk counseling and development of postoperative treatment pathways. We aimed to classify causes for recurrent symptoms in all patients undergoing first rib resection and anterior scalenectomy for TOS.

PC120 The Natural History of Carotid Occlusion

June 1, 2017 - 00:00
Carotid stenosis is an important risk factor for ischemic stroke. The management of asymptomatic carotid stenosis is controversial, with various approaches recommending revascularization with carotid endarterectomy or carotid stent for stenosis of 60% to 99%, revascularization for stenosis >75%, revascularization for high-risk patients only, or intensive modern medical treatment. Few studies have noted the incidence of neurologic events in medically treated patients who progress to carotid occlusion.

PC118 Carotid Endarterectomy vs Carotid Stenting: 10-Year Comparative Analysis

June 1, 2017 - 00:00
Carotid artery stenting (CAS) remains an effective alternative to carotid endarterectomy (CEA) for stroke prevention; however, the long-term durability of CAS remains poorly defined. We performed a 10-year comparative analysis of CEA and CAS to help better evaluate the durability of these procedures.

PC116 Predisposing Factors to Postoperative Hypotension Following Carotid Artery Stenting

June 1, 2017 - 00:00
This study determined factors associated with hypotension following carotid artery stenting (CAS). In particular, this study evaluated whether involvement of the carotid bifurcation/bulb and degree of calcification can predict postoperative hypotension.

PC114 Predictors of Poor Outcome After Carotid Intervention

June 1, 2017 - 00:00
A variety of patient factors are known to adversely impact outcomes after carotid endarterectomy (CEA) or carotid artery stenting (CAS). However, their specific impact on complications and mortality and how they differ between CEA and CAS is unknown. The purpose of this study was to identify patient and hospital factors that adversely impact outcomes.

PC112 Statins Reduce Mortality and Failure to Rescue Following Carotid Artery Stenting

June 1, 2017 - 00:00
The benefit of statins has been well-established following lower extremity revascularization and carotid endarterectomy. However, the potential advantage of statin use in patients undergoing carotid artery stenting (CAS) remains largely unknown. The purpose of this study was to evaluate the effect of statins on postoperative outcomes following CAS.

PC110 Carotid Access to Deliver Large Endovascular Devices in Patients With Inadequate Iliofemoral Access

June 1, 2017 - 00:00
Safe delivery of large endovascular devices can be problematic in patients with inadequate iliofemoral access. We describe the technique and outcomes using carotid access for endovascular device delivery in patients with inadequate iliofemoral access.

PC108 Evaluation of an ePTFE Endograft Placed at the Time of Arteriovenous Fistula Creation to Prevent Juxta-anastomotic Stenosis and Improve Maturation and Long-Term Patency Rates

June 1, 2017 - 00:00
We evaluated the feasibility, safety and therapeutic advantage of an expanded polytetrafluoroethylene (ePTFE) endograft placement within the juxta-anastomotic segment of an arteriovenous fistula (AVF) at the time of fistula creation: The JuxtaBahn Procedure. This novel technique is an attempt to prevent juxta-anastomotic stenosis, which is a major contributing factor (40%-60%) leading to AVF failure. We are reporting the adverse effect profile and time-stamped outcome measures in terms of maturation, patency, reintervention frequency, stenosis patterns, and their effect on fistula viability.

PC106 Point-of-Care Ultrasound (POCUS) Use as Adjunct to Physical Examination and Its Impact on Arteriovenous Fistula Maturation

June 1, 2017 - 00:00
Duplex ultrasound imaging as a preoperative assessment tool in clinic may help identify anatomical factors predictive of fistula maturation. Point-of-care ultrasound (POCUS) may decrease costs to the health care system and decrease time to access creation as compared to formal vein mapping. We sought to determine the impact of POCUS as an adjunct to physical examination on arteriovenous fistula maturation.

PC104 The Role of Duplex Ultrasound in Assessing AVF Maturation

June 1, 2017 - 00:00
Arteriovenous fistulas (AVF) are favored for hemodialysis (HD) access due to their superior long-term patency and lower risk of infectious complications. However, in many instances, AVFs fail to mature. The goal of this study was to examine the utility of postoperative color duplex ultrasound (CDUS) imaging in assessing AVF primary maturation and determining the need for balloon-assisted maturation (BAM).

PC102 Hybrid Vascular Graft for Vascular Access Creation: A Single-Center Experience

June 1, 2017 - 00:00
Arteriovenous grafts (AVG) present a feasible solution for creating a vascular access in patients who are unsuitable for autogenous fistulas (AVF). The quite poor outcomes associated with AVG are largely due to neointimal hyperplasia in the venous anastomosis. The aim of this study was to assess the patency rate of GORE Hybrid Vascular Grafts (HG) in vascular access for hemodialysis.

PC098 Repeated Endovascular Interventions Is Worthwhile to Maintain Long-Term Patency of Autogenous Dialysis Fistulas

June 1, 2017 - 00:00
It is well established that autogenous arteriovenous fistulas (aAVF) are the preferred conduit for hemodialysis access. There is no consensus, however, on whether multiple interventions on aAVF, particularly following thrombosis, are worthwhile in order to extend functional fistula patency (FFP) and minimize the use of alternative conduits and catheters. We wanted to evaluate whether our policy of repeated interventions for failing or failed aAVF was effective in prolonging their FFP.

PC096 Recent Trends in Publications of U.S. Vascular Surgery Program Directors

June 1, 2017 - 00:00
In order to examine academic productivity of United States vascular surgery program directors, the number of vascular publications listed in PubMed from 2001 to 2015 for United States vascular surgery program directors was reviewed. We suggest that this can be used as a benchmark for academic productivity. Furthermore, trends in these publications were noted.

PC094 Increasing the Number of Integrated Vascular Surgery Residency Positions Is Necessary to Address the Impending Shortage of Vascular Surgeons in the United States

June 1, 2017 - 00:00
The demand for vascular surgeons in the next two decades is expected to far exceed the current supply. While the number of fellowship programs is stable, the numbers of vascular residency programs and positions have expanded dramatically. We sought to evaluate the qualifications and characteristics of this new workforce in terms of its ability to meet the future needs.

PC092 Prospective Validation of High-Fidelity Simulation of Endovascular Aortic Aneurysm Repair Using 3D Printed Aortic Model and Fluid Pump

June 1, 2017 - 00:00
This study investigated the feasibility of endovascular aortic aneurysm repair (EVAR) training using high-fidelity simulation with a three-dimensional (3D) printed aortic model connected to hemodynamic pump.

PC090 Use of Google Glass in Education of Vascular Surgery

June 1, 2017 - 00:00
The aim of this pilot study was to describe the role of Google Glass (GG) in teaching remote surgeons sitting out of hospital.

PC088 The Impact of Psychological Comorbidities on Patient-Reported Outcomes in Adults With MALS

June 1, 2017 - 00:00
Median arcuate ligament syndrome (MALS) remains a challenging vascular problem to treat, in part because the symptoms overlap with many other gastrointestinal (GI) diagnoses as well as chronic abdominal pain. In our previous work, we have demonstrated that children (aged <17 years) with MALS have similar psychosocial profiles to children with other GI disorders resulting in chronic abdominal pain. The goal of this study was to outline the psychosocial profile of adults presenting with MALS, to define the patient-reported outcomes of surgery, and to determine whether psychologic comorbidities impact these outcomes.

PC086 Endovascular Interventions in the Management of Postpartum Hemorrhage due to Placenta Accreta

June 1, 2017 - 00:00
Placenta accreta, an abnormal placental adherence to the myometrium, is a major risk factor for massive postpartum hemorrhage (PPH). Placenta accreta-induced PPH can be life-threatening, requiring multiple transfusions and emergency hysterectomy. There are reports describing favorable outcomes using endovascular techniques to limit PPH, although this has not been widely reported in the vascular surgical literature. Most interventions are directed at the internal iliac or uterine artery, with the goal of reducing flow in the peripartum and postpartum period and mitigating placental hemorrhage and the need for hysterectomy.

PC084 Natural History and Management of Splanchnic Artery Aneurysms in a Single Tertiary Referral Center

June 1, 2017 - 00:00
Splanchnic artery aneurysms (SAA) are rare, and little is known about their natural history and management. We reviewed our single-center experience managing this patient population.

PC082 Effect of Stent Design on Branch Vessel Outcomes in Fenestrated Endografting of Complex Aortic Aneurysms

June 1, 2017 - 00:00
The ideal mating stent for target vessel revascularization in fenestrated/branched endograft (F/B-EVAR) repair of juxtarenal aortic aneurysm (JRAA) and thoracoabdominal aortic aneurysms (TAAA) remains unknown. The objective of this study was to assess the impact and complications associated with use of different stent types and configurations mated with reinforced fenestrations during F/B-EVAR.
