BACKGROUND: Preliminary results in small single-center studies after stenting with the GORE TIGRIS Vascular Stent (W. L. Gore & Associates, Flagstaff, Ariz) show promising short-term primary patency rates, but larger, multicenter studies are needed. This study therefore investigated the performance of the GORE TIGRIS Vascular Stent at three different centers in France in patients with symptomatic peripheral artery disease. METHODS: This retrospective, single-arm, multicenter cohort study included 215 patients with peripheral artery disease (Rutherford-Becker category 2-6) who were treated with the GORE TIGRIS Vascular Stent, a dual-component stent consisting of a nitinol wire frame combined with a fluoropolymer-interconnecting structure...

OBJECTIVE: Popliteal artery entrapment syndrome (PAES) is an uncommon anatomical anomaly, frequently described in adults. The most common symptom is claudication. Acute limb ischaemia (ALI) in children is rare, but it may evolve and lead to limb loss or lifelong complications. Clinical and surgical experience of PAES in children is reported. Data from the literature are analysed in order to assess the severity of this disease and to identify the factors characterising the diagnosis and the outcome of treatment in paediatric patients...

Background -Atherosclerotic peripheral artery disease (PAD) affects 8-12% of Americans over 65 and is associated with a major decline in functional status, increased myocardial infarction and stroke rates, and increased risk of ischemic amputation. Current treatment strategies for claudication have limitations. PACE is an NHLBI-sponsored, randomized, double-blind, placebo-controlled phase 2, exploratory clinical trial designed to assess safety and efficacy of autologous bone marrow-derived aldehyde dehydrogenase bright (ALDHbr) cells in PAD patients and to explore associated claudication physiologic mechanisms...

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...

INTRODUCTION: Infra-popliteal angioplasty continues to be widely performed with minimal evidence to guide practice. Endovascular device selection is contentious and there is even uncertainty over which artery to treat for optimum reperfusion. Direct reperfusion (DR) targets the artery supplying the ischaemic tissue. Indirect reperfusion (IR) targets an artery supplying collaterals to the ischaemic area. Our unit practice for the last eight years has been to attempt to open all tibial arteries at the time of angioplasty...

Diplopodia, being a rare congenital disorder, is infrequently discussed in published texts. Most reported cases have accounted the involvement of duplicated preaxial digits with other associated organ system and physical deformities. Here, we present an unusual case of isolated diplopodia involving postaxial toes in a child with no other organ and physical abnormalities. Radiological studies revealed a set of 10-digit-duplicated foot over the lateral aspect of the native foot, complete with phalanges and its corresponding metatarsals as well as tarsals, supplied by an anomalous posterior branch of the popliteal artery...

Oversizing of the Nitinol stents in the femoro-popliteal arterial tract is commonly performed by clinicians and further encouraged by stent manufacturers. However, in spite of the procedure's supposed benefits of strong wall apposition and increased luminal gain, its effects on the mechanical behavior of arteries with peripheral arterial disease are not fully clear. In this study, finite element (FE) analyses of endovascular revascularization of an idealized artery with 70% stenosis and three different plaque types have been performed to examine the influence of Nitinol stent oversizing on the arterial stresses and acute lumen gain...

Increased daily sitting time is associated with greater cardiovascular risk, and on average women are more sedentary than men. Recent reports have demonstrated that prolonged sitting reduces lower leg microvascular (reactive hyperemia) and macrovascular (flow-mediated dilation, FMD) vasodilator function. However, these studies have predominately included men, and the effects of sitting in young women are largely unexplored. This becomes important given known sex differences in vascular function. Thus herein, we assessed popliteal artery reactive hyperemia and FMD, before and after a 3hr sitting period, in healthy young women (n=12) and men (n=8)...

BACKGROUND: Reconstruction of the popliteal fossa using a free flap is challenging. Therefore, to facilitate easier free flap reconstruction of the popliteal fossa, we use a medial sural artery perforator (MSAP) free flap with a medial sural vessel as the recipient vessel, as it provides several advantages based on many reports. METHODS: This report describes the authors' experience and outcomes with this technique. Between October 2010 and January 2015, 10 patients with medium-sized defects in their popliteal fossa underwent MSAP free flap reconstruction using the medial sural vessel as the recipient vessel...

BACKGROUND Popliteal fossa pseudoaneurysms as a result of trauma are not uncommon. However, spontaneous pseudoaneurysms as a result of non-traumatic rupture of posterior tibial artery (PTA), anterior tibial artery (ATA), or tibioperoneal trunk (TPT) artery segment are extremely rare. We report a case of spontaneous popliteal fossa pseudoaneurysm resulting from spontaneous avulsion of the ATA and transection of the TPT. Despite a thorough workup, no underlying associated disease was found. The extreme rarity of this disease presentation prompted us to report this case...

BACKGROUND: Critical limb ischemia (CLI), despite revascularization, may result in minor or major amputations with devastating psychological effects and a negative impact on patient survival. Randomized clinical trials demonstrated that drug-eluting stents improve 1-year primary patency and decrease target lesion revascularization, compared to standard angioplasty and bare-metal stents, in patients with short occlusive below-the-knee lesions. OBJECTIVES: This prospective clinical study was designed to evaluate if one straight-line flow revascularization to the foot, using Xience-Prime Everolimus-Eluting Stent (EES), is an effective treatment of patients in Rutherford-Becker category 4 to 5 with distal popliteal and proximal tibial arteries long occlusive lesions up to 10 cm...

Microvascular and macrovascular dysfunction plays an important role in the pathogenesis of diabetic vascular disease. Twenty-nine older patients with type 2 diabetes were randomly assigned into the land-based (LB; n=14) or water-based (WB; n=15) groups. Both groups completed supervised aerobic cycling exercises 3 times per week for 12 weeks. The WB group performed cycling exercise training in warm water (36°C) immersed to the hip level. After 12 weeks, blood glucose concentration and insulin resistance did not change but hemoglobin A1c levels decreased (P<0...
