BACKGROUND: Peripheral arterial disease poses a significant burden in the hemodialysis (HD)-dependent population. Race is a known modifier of outcomes after surgical treatment of peripheral arterial disease. A comprehensive evaluation of the effect of race on infrainguinal bypass surgery (IBS) outcomes in HD patients is lacking. In this study, we evaluated the effects of race on long-term IBS outcomes in a large, nationally representative cohort of HD patients. METHODS: We studied all HD patients who underwent IBS between January 2007 and December 2011 in the United States Renal Disease System-Medicare matched database...

OBJECTIVE: It is unclear whether frailty adversely affects treatment outcomes in patients with critical limb ischemia (CLI). The aim of this study was to investigate the influence of frailty on CLI patients after revascularization. METHODS: Patients undergoing infrapopliteal revascularization between 2007 and 2015 were retrospectively analyzed. The patient was defined as CLI frail when two or more of the following were present: low Geriatric Nutritional Risk Index, low skeletal muscle mass index, or nonambulatory status...

OBJECTIVE: Digital subtraction angiography (DSA) of the peripheral arterial vasculature provides lumenographic information but only a qualitative assessment of blood flow. The ability to quantify adequate tissue perfusion of the lower extremities would enable real-time perfusion assessment during DSA of patients with peripheral arterial disease (PAD). In this study, we used a novel real-time imaging software to delineate tissue perfusion parameters in the foot in PAD patients. METHODS: Between March 2015 and June 2016, patients (N = 31) underwent lower extremity angiography using a two-dimensional perfusion (2DP) imaging protocol (Philips Healthcare, Andover, Mass)...

OBJECTIVE: Venous valves are essential but are prone to injury, thrombosis, and fibrosis. We compared the behavior and gene expression of smooth muscle cells (SMCs) in the valve sinus vs nonvalve sites to elucidate biologic differences associated with vein valves. METHODS: Tissue explants of fresh human saphenous veins were prepared, and the migration of SMCs from explants of valve sinus vs nonvalve sinus areas was measured. Proliferation and death of SMCs were determined by staining for Ki67 and terminal deoxynucleotidyl transferase dUTP nick end labeling...

BACKGROUND: Peripheral artery disease (PAD) is a highly prevalent disease that impairs walking ability. Walking tests, such as the 6-minute walk test (6MWT) and 4-meter walk test, are commonly used to assess exercise endurance and ambulatory function over a short distance, respectively. The 6MWT performance is predictive of PAD severity and disease outcomes, but it is not feasible in many clinical settings because it requires a long walkway to serve as the test route and lengthens clinic visits...

OBJECTIVE: The durability of cryopreserved allograft has been previously demonstrated in the setting of infection. The objective of this study was to examine the safety, efficacy, patency, and cost per day of graft patency associated with using cryopreserved allograft (vein and artery) for hemodialysis access in patients with no autogenous tissue for native fistula creation and with arteriovenous graft infection or in patients at high risk for infection. METHODS: Patients implanted with cryopreserved allograft for hemodialysis access between January 2004 and January 2014 were reviewed using a standardized, multi-institutional database that evaluated demographic, comorbidity, procedural, and outcomes data...

OBJECTIVE: Studies have shown that language discordance between treatment teams and patients leads to worse patient outcomes, including longer hospital stays, higher rates of readmission, impaired comprehension of discharge instructions, and lower treatment adherence. Yet, there is a paucity of data evaluating the effects of language discordance on postoperative outcomes among vascular surgery patients. This study compared 30-day postoperative complications and readmissions after nonemergent infrainguinal bypass between non-English-speaking (NES) and English-speaking (ES) patients...

OBJECTIVE: An arteriovenous bridging graft is a viable option for patients with compromised arteries or veins because of advanced age or diabetes. Arteriovenous graft with graft insertion anastomosis (AVGI) is the novel technique for graft-vein anastomosis where the prosthesis is inserted into the vein, and the anastomosis is performed on the surface of the prosthesis. This study assessed the short-term and long-term results of AVGI to clarify the efficacy of this technique. METHODS: Between 2010 and 2015, AVGI was performed in graft-vein anastomosis of prosthetic forearm loop access...

OBJECTIVE: We compared the management of patients with symptomatic, unruptured abdominal aortic aneurysms (AAAs) treated at a tertiary care center between two decades. This 20-year period encapsulated a shift in surgical approach to aortic aneurysms from primarily open to primarily endovascular, and we sought to determine the effect of this shift in the evaluation, treatment, and clinical outcomes of patients with symptomatic AAA. METHODS: We reviewed 1429 consecutive patients with unruptured AAAs treated at a tertiary care hospital by six staff surgeons between 1995 and 2004 (era 1) and between 2005 and 2014 (era 2)...

OBJECTIVE: Carotid endarterectomy (CEA) has been shown to be an effective treatment for patients with asymptomatic carotid artery stenosis when perioperative stroke rates are low and patients survive long enough to benefit from the intervention. Our objective was to develop and to validate a simple risk prediction model for 30-day stroke and 1-year mortality to guide optimal selection of patients for CEA. METHODS: Asymptomatic patients undergoing first-time elective CEA within the Vascular Quality Initiative (VQI) from 2010 to 2015 were selected...

Gregory A Stanley
The GORE TAG Thoracic Endoprosthesis (TAG) device (W. L. Gore & Associates, Flagstaff, Ariz) and the GORE Conformable TAG Thoracic Endoprosthesis (CTAG) are commonly implanted and effective stent grafts for use during thoracic endovascular aortic repair. Precise placement of the endograft is paramount during thoracic endovascular aortic repair, but like all thoracic stent grafts, maldeployment with inaccurate landing has been reported. The partial distal deployment technique describes an alteration of the TAG and CTAG deployment mechanism to allow isolated deployment of the distal half of the graft, which provides stability during deployment...
