OBJECTIVE: Therapeutic anticoagulation (AC) is used clinically for prolongation of infrainguinal bypass patency, but evidence for the efficacy of this practice is conflicting. The objective of our study was to determine the association of AC with bypass graft primary patency. METHODS: Clinical and comorbid data of patients undergoing infrainguinal bypass grafts to a below-knee target with at least 1 year of follow-up performed from 2003 to 2015 were obtained from the Society for Vascular Surgery Vascular Quality Initiative...

BACKGROUND: A long period is generally required for ischemic ulcer to heal after revascularization. The strategy of postoperative wound care can affect wound healing. This study was conducted to investigate the degree to which aggressive wound care (AWC) by a team of multidisciplinary specialists actually shortens the time to wound healing and increases the rate of wound healing in limbs undergoing surgical bypass for ischemic tissue loss in a real clinical setting. METHODS: A total of consecutive 126 patients undergoing infrainguinal bypass for tissue loss from April 2011 to March 2015 were reviewed...

Critical limb ischemia (CLI) represents the terminal stage of peripheral arterial disease (PAD) and is characterized by multilevel and multivessel disease. Amongst patients with infrainguinal disease, approximately one third have predominantly isolated infrapopliteal disease and the remaining two thirds, a combination of femoropopliteal and infrapopliteal disease. Isolated infrapopliteal disease is mainly seen in the elderly, diabetic, or dialysis-dependent patients. These patients have higher risk of amputation and shorter amputation-free survival...

OBJECTIVE: Patients undergoing lower extremity bypass (LEB) are at high risk of perioperative complications that can lead to a cascade of secondary complications. Our goal was to understand the association of index complications with secondary complications after LEB. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database from 2005 to 2012 was used to analyze secondary complications after five index complications after LEB: deep/organ space surgical site infection, urinary tract infection (UTI), myocardial infarction (MI), pneumonia, and acute renal failure (ARF)...

In recent years, the retrograde tibiopedal approach is increasingly being used for revascularization of complex chronic total occlusions of infrainguinal arteries to bailout those cases where a guidewire was not possible to pass through the lesion from antegrade and therefore the treatment would have failed. The present popularity of this technique is in contrast to the paucity of data published so far. Nevertheless, from the reports that are available and from the authors' experience we conclude that it is not only a successful but also a safe technique...

OBJECTIVE: Unplanned hospital readmissions following surgical interventions are associated with adverse events and contribute to increasing health care costs. Despite numerous studies defining risk factors following lower extremity bypass surgery, evidence regarding readmission after endovascular interventions is limited. This study aimed to identify predictors of 30-day unplanned readmission following infrainguinal endovascular interventions. METHODS: We identified all patients undergoing an infrainguinal endovascular intervention in the targeted vascular module of the American College of Surgeons National Surgical Quality Improvement Program between 2012 and 2014...

OBJECTIVES: This study aimed to assess the optimal angiographic endpoint of endovascular therapy (EVT) for wound healing. BACKGROUND: Several reports have demonstrated acceptable patency and limb salvage rates following infrapopliteal interventions for the treatment of critical limb ischemia (CLI). However, the optimal angiographic endpoint of EVT remains unclear. METHODS: We conducted a subanalysis of the prospective multicenter OLIVE (Endovascular Treatment for Infrainguinal Vessels in Patients with Critical Limb Ischemia) registry investigation assessing patients who received infrainguinal EVT for CLI...

Orbital atherectomy has been developed as a method to modify calcified plaque in the peripheral vasculature, with extensive experience and data supporting its use in infrainguinal peripheral arterial disease. However, calcific atherosclerotic disease occurs in other vascular beds and may benefit from the application of this technology. In this case report, we describe the first reported use of orbital atherectomy in a renal artery. A 55-year-old male with severe drug-refractory hypertension was found to have renal artery stenosis, with severe calcification of the right renal artery...

BACKGROUND: There are only a few options to replace infected infrainguinal synthetic vascular grafts in the absence of suitable autologous veins. To use a biosynthetic vascular graft (Omniflow(®)II) might be a valuable alternative. METHODS: We retrospectively analyzed the clinical course of 29 patients who underwent replacement of an infected infrainguinal vascular prosthesis (Szilagyi 3) by an Omniflow(®)II graft. RESULTS: Because of the lack of suitable autologous veins, 15 above-knee femoro-popliteal, 5 below-knee femoro-popliteal, and 9 femoro-tibial bypasses were replaced with biosynthetic grafts...

REVIEW
Olivia M McBRIDE, Roderick T Chalmers
Despite advances in endovascular strategies, surgical infrainguinal lower limb revascularization remains the gold standard treatment for critical lower limb ischemia and disabling claudication. Maintaining patency of infrainguinal vein bypass grafts has been a challenging task for vascular surgeons as they are prone to developing stenoses which may precipitate failure of the bypass. Duplex ultrasound scanning has evolved as the investigation of choice to identify vein graft lesions but graft surveillance programs using this technique remain controversial...

BACKGROUND: The Vascular Study Group of New England (VSGNE) requires documentation of follow-up for >80% of patients at least 9 months postprocedure. 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 to 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 postprocedure...
