OBJECTIVE: The Vascular Study Group of New England (VSGNE) requires documentation of follow-up for >80% of patients at least 9 months post-procedure. However, many participating groups fall short of this goal. We sought to identify factors independently associated with loss to long-term follow-up (LTF). METHODS: The VSGNE was queried from 2008-2012, for all carotid endarterectomy (CEA), endovascular aneurysm repair (EVAR), open abdominal aortic aneurysm repair (OPEN), infrainguinal bypass (INFRA), and suprainguinal bypass (SUPRA) procedures in patients who survived greater than 9 months post-procedure...

INTRODUCTION: Duplex Ultrasound (DU) based graft surveillance remains controversial. The aim of this study was to assess the ability of a recently proposed decision tree in identifying high-risk grafts which would benefit from DU based surveillance. MATERIALS AND METHODS: Consecutive patients undergoing infrainguinal vein graft bypass from January 2008 to December 2015 were identified from the National Vascular registry and enrolled in a duplex surveillance program...

OBJECTIVES: An occluded lower limb arterial bypass is associated with poor prognosis for the limb. Currently, no risk assessment method to estimate the risk of early graft failure exists. Aim of this study was to investigate the effect of various potential factors on early graft failure of infrainguinal bypass surgery and to develop a risk-scoring model to predict it. DESIGN AND METHODS: A prospective observational clinical study was performed. One hundred infrainguinal bypass procedures (60 autologous and 40 synthetic grafts), throughout a 3-year period were included...

OBJECTIVE: The development of acute kidney injury (AKI) and its effect on prognosis after lower extremity bypass (LEB) surgery have not been well described. We determined risk factors associated with AKI in patients undergoing infrainguinal LEB surgery and whether individuals with AKI are at increased risk for cardiovascular events and mortality. METHODS: Data for 12,907 operations entered in the Vascular Quality Initiative (VQI) registry from January 2012 through April 2015 were retrospectively reviewed...

OBJECTIVE: Postoperative respiratory adverse events (RAEs) are associated with high rates of morbidity and mortality in general surgery, however, little is known about these complications in the vascular surgery population, a frail subset with multiple comorbidities. The objective of this study was to describe the contemporary incidence of RAEs in vascular surgery patients, the risk factors for this complication, and the overall impact of RAEs on patient outcomes. METHODS: The Vascular Quality Initiative was queried (2003-2014) for patients who underwent endovascular abdominal aortic repair, open abdominal aortic aneurysm repair, thoracic endovascular aortic repair, suprainguinal bypass, or infrainguinal bypass...

OBJECTIVES: The aim of this study was to assess actual procedural costs and outcomes comparing wire-catheter and dedicated chronic total occlusion (CTO) device strategies to cross peripheral artery CTOs. BACKGROUND: Peripheral artery CTO interventions are frequently performed, but there are limited data on actual procedural costs and outcomes comparing wire-catheter and dedicated CTO devices. METHODS: The XLPAD (Excellence in Peripheral Artery Disease Intervention) registry (NCT01904851) was accessed to retrospectively compare cost and 30-day and 12-month outcomes of wire-catheter and crossing device strategies for treatment of infrainguinal peripheral artery CTO...

INTRODUCTION: Popliteal artery aneurysms (PAA) are the most prevalent form of peripheral arterial aneurysms. Greater saphenous vein grafts and endoaneurysmorrhaphy remains the mainstay therapy for open repair of PAA. True aneurysmal degeneration of lower extremity infrainguinal autologous vein grafts are relatively rare and its etiology is not completely understood. CASE PRESENTATION: We present a case of a 57-year-old man with recurrent autologous venous graft aneurysmal dilatations following a surgical popliteal artery aneurysm repair...

Importance: Intermittent claudication (IC) is the most common presentation of infrainguinal peripheral artery disease. Both medical and revascularization interventions for IC aim to increase walking comfort and distance, but there is inconclusive evidence of the comparative benefit of revascularization given the possible risk of limb loss. Objective: To compare the effectiveness of a medical (walking program, smoking cessation counseling, and medications) vs revascularization (endovascular or surgical) intervention for IC in the community, focusing on outcomes of greatest importance to patients...

AIM: The treatment strategy for hemodialysis (HD) patients with critical limb ischemia (CLI) has been clinically debatable. Here we compared clinical outcomes after bypass surgery (BSX) and after endovascular therapy (EVT) using propensity score matching. METHODS: A retrospective multicenter database of 246 (68 BSX and 178 EVT) consecutive HD patients with CLI (79% with tissue loss) who underwent infrainguinal revascularization from 2007 to 2009 was used to compare clinical outcomes, including overall survival (OS), major amputation (MA), major adverse limb event (MALE: repeat EVT, surgical reconstruction, or MA), and MALE-free survival after BSX vs...

OBJECTIVE: Prior studies on the cause and effect of surgical variation have been limited by utilization of administrative data. The Vascular Quality Initiative (VQI), a robust national clinical registry, provides anatomic and perioperative details allowing a more robust analysis of variation in surgical practice. METHODS: The VQI was used to identify all patients undergoing infrainguinal open bypass or endovascular intervention from 2009 to 2014. Asymptomatic patients were excluded...

Endovascular techniques have improved markedly over the past several decades. Plain old balloon angioplasty can only reach patencies around 40% after 1 year. Scaffolding stents have resulted in improved short-term results but encountered limitations for longer-term durability. With the introduction of drug-eluting technologies the process of intimal hyperplasia might be slowed, resulting in improved long-term patency results. At first, limus-eluting technologies were not able to transfer the enthusiasm from the coronaries to the infrainguinal vascular bed...

OBJECTIVE: Supervised exercise is currently recommended for the first-line treatment of intermittent claudication based on improvement in walking capacity. However, the promotion of skeletal muscle atrophy by repetitive ischemia-reperfusion caused by treadmill-based programs remains a concern. Because preservation of skeletal muscle mass (SMM) and lean mass (LM) is integral to functional capacity and longevity, this study measured the effect of standard treadmill-based supervised exercise on SMM and regional lower limb LM in patients with intermittent claudication...

BACKGROUND: Isolated common femoral endarterectomy was recently reported to have a 30-day mortality of 3.4%. The effect of adjunctive femoral endarterectomy at the time of lower extremity bypass is not well described, and therefore, the purpose of this study was to determine its associated perioperative and long-term risk. METHODS: Vascular Study Group of New England registry data were used to identify patients undergoing initial lower extremity bypass from 2003 to 2015...

OBJECTIVES: Thrombolysis has been reported to be suboptimal in occluded vein grafts and cryopreserved allografts, and there are no data on the efficacy of thrombolysis in occluded cold stored venous allografts. The aim was to evaluate early outcomes, secondary patency and limb salvage rates of thrombolysed cold stored venous allograft bypasses and to compare the outcomes with thrombolysis of autologous bypasses. METHODS: This was a single center study of consecutive patients with acute and non-acute limb ischemia between September 1, 2000, and January 1, 2014, with occlusion of cold stored venous allografts, and between January 1, 2012, and January 1, 2014, with occlusion of autologous bypass who received intra-arterial thrombolytic therapy...
