OBJECTIVE: We sought to analyze the outcomes of revascularization for aortoiliac-femoral occlusive disease by comparing hybrid repair by endovascular revascularization and open common femoral endarterectomy (ER-CFE) with open aortoiliac reconstruction and CFE (OR-CFE). METHODS: Using the national Society for Vascular Surgery Vascular Quality Initiative database from 2009 to 2015, we identified all patients receiving open or endovascular revascularization of the aortoiliac system and who additionally underwent CFE...

The present study investigated the incidence, causes, treatment and prevention of limb graft occlusion following endovascular aortic repair (EVAR). A total of 66 cases of abdominal aortic aneurysm receiving EVAR at our department from January 2005 to December 2013 were enrolled. After EVAR, patients received routine antiplatelet therapy of 75 mg PLAVIX for 6 months and then 100 mg Aspirin for another 6 months by oral administration. According to previous clinical experiences, antiplatelet therapy is able to effectively reduce the incidence of iliac occlusion after EVAR...

Bone marrow fat is a unique fat depot that may regulate bone metabolism. Marrow fat is increased in states of low bone mass, severe underweight, and diabetes. However, longitudinal effects of weight loss and improved glucose homeostasis on marrow fat are unclear, as is the relationship between marrow fat and bone mineral density (BMD) changes. We hypothesized that after Roux-en-Y gastric bypass (RYGB) surgery, marrow fat changes are associated with BMD loss. We enrolled 30 obese women, stratified by diabetes status...

Ulnar arterial access for cardiac catheterization and intervention is an alternative approach compared with radial or femoral access. Ulnar access is infrequently performed since the radial artery is readily palpable and is commonly used worldwide to minimize vascular complications from femoral access. Nevertheless, ulnar access provides a suitable access site in patients who are poor candidates for femoral access, have pre-existing radial occlusion, radial artery hypoplasia or hyperplasia from prior radial artery procedures, radial stenosis, radial loops, radial tortuosity, small radial arteries, and/or have future need for radial graft for dialysis or coronary artery bypass graft...

BACKGROUND: It is imperative to gain safe access into the occluded targeted vessel and begin treating acute extremity limb ischemia. Often the origin of the targeted native artery or bypass graft will have a flush occlusion making it difficult to cannulate. This paper looks at the novel use of portable ultrasound to evaluate the origin of the artery or bypass graft to help facilitate the start of thrombolysis. METHODS: We reviewed our last 2 years of acute limb ischemia in our patients with high risk factors and co-morbidities...

BACKGROUND: Paclitaxel-eluting balloon (PEB) angioplasty has superior efficacy compared with conventional balloon angioplasty (BA) for de novo lesions of superficial femoral artery (SFA). Studies investigating the angiographic and clinical performance of PEB angioplasty versus BA for in-stent restenosis of SFA are limited. We performed a randomized trial to investigate angiographic and clinical performance of PEB versus BA for in-stent restenosis of SFA. METHODS AND RESULTS: Patients with symptomatic in-stent restenosis of SFA were randomly assigned to either PEB or BA at 2 centers in Munich, Germany...

BACKGROUND: Popliteal artery entrapment syndrome is an uncommon condition in which anatomic or functional popliteal artery compression causes arterial insufficiency. We present a case of popliteal entrapment with runoff thrombosis treated with suprageniculate release of entrapment without distal bypass. RESULTS: A 15-year old boy with Klinefelter syndrome presented with right leg claudication severely limiting his activity. He had a palpable femoral pulse, but no palpable popliteal or foot pulses on the right...

BACKGROUND: Severe aorto-iliac occlusive disease (AIOD) is traditionally treated with aorto-bifemoral (ABF) or aorto-unifemoral (AUF) bypass. However, cross-femoral bypass (CFB) and hybrid femoral endarterectomy and patch angioplasty with iliac stenting (EPS) have gained popularity as less invasive options. We sought to compare 1-year survival, primary patency, and major amputation rates between open surgical (ABF and AUF) and two less invasive reconstruction techniques (CFB and EPS) using a large, multicenter cohort...

A 94-year-old woman with rupture of a thoracic aortic aneurysm (rTAA) was referred to us. She previously underwent thoracic endovascular aortic repair and was considered to be at high risk for a conventional open operation. Therefore an endovascular procedure was planned. The proximal landing zone needed to be placed at the ascending aorta to seal a type 1a endoleak. A hybrid operation consisting of supraaortic total debranching on the common femoral artery and endovascular repair was performed. All debranched bypasses were patent and the aneurysm was excluded...

This work is a thorough nonsystematic critical review (PubMed/MEDLINE 1950-September 2016) of "disruption in nonanastomotic section of an axillofemoral bypass." Fourteen cases were selected (including that provided by the authors of this publication) dating from 1963 to 2016 (53 years). This type of disruption is a very unusual complication in the axillofemoral bypass. The cases described reveal that this disorder is more frequent in unifemoral bypass (9 cases), in ringed polytetrafluorethylene, in blunt trauma, and at costal level especially on the left side...

BACKGROUND: Hemodialysis dependence confers unique physiologic conditions. Prior reports of outcomes after infrainguinal open bypass operations in patients on hemodialysis have been based on relatively small sample institutional series. In this study, we evaluate long-term outcomes after open bypass operations in a large contemporary population-based cohort of hemodialysis patients. We studied all hemodialysis patients who underwent infrainguinal open operation using autogenous versus prosthetic conduits in the United States Renal Data System between January 2007 and December 2011...

OBJECTIVE: The objective of this study was to describe our experience with endovascular aneurysm repair (EVAR) with the use of chimney grafts for branch vessel preservation. METHODS: Patients treated with a chimney graft procedure between October 2009 and May 2015 were included for analysis. Patients who were not considered eligible for open surgical repair or for conventional, branched, or fenestrated endovascular repair were selected. A standardized operating procedure with left brachial or axillary artery cutdown access for the chimney grafts and bilateral femoral artery cutdown access for the aortic main device was used...

Arterial reconstruction, whether angioplasty or bypass surgery, involves iatrogenic trauma causing endothelial disruption and vascular smooth muscle cell (VSMC) proliferation. Common murine models study small vessels such as the carotid and femoral arteries. Herein we describe an in vivo system in which both VSMC proliferation and endothelial barrier function can be simultaneously assessed in a large vessel. We studied the infrarenal aortic response to injury in C57BL/6 mice. The aorta was injured from the left renal vein to the aortic bifurcation by 30 transmural crushes of 5-seconds duration with a cotton-tipped applicator...
