Objective: To compare long-term patency after endovascular therapy (EVT) for superficial femoral artery (SFA) occlusive disease between patients with hemodialysis (HD; HD+) and those without HD (HD−).
Background: Drug-coated balloon angioplasty (DCBA) was shown to be superior to standard balloon angioplasty (POBA) in terms of restenosis prevention for de novo superficial femoral artery disease. For in-stent restenosis, the benefit of DCBA over POBA remains uncertain.
Background: There are limited data on femoropopliteal artery stent thrombosis (ST), which is a serious adverse outcome of peripheral artery interventions.
Objectives: The aim of this study was to assess factors influencing the clinical outcome and morphological changes of acute and chronic type B aortic dissection after thoracic endovascular aortic repair (TEVAR).
Background: Evidence from large, randomized, controlled peripheral artery disease trials reporting long-term outcomes using drug-coated balloons (DCBs) is limited. Previously, the DCB showed favorable 1-year outcomes compared with conventional percutaneous transluminal angioplasty (PTA), yet durability of the treatment effect with DCBs remains unknown.
Background: Multiple randomized clinical trials comparing renal artery stent placement plus medical therapy with medical therapy alone have not shown any benefit of stent placement. However, debate continues whether patients with extreme pressure gradients, stenosis severity, or baseline blood pressure benefit from stent revascularization.
Background: Use of blood oxygenation level-dependent cardiovascular magnetic resonance (BOLD-CMR) to assess perfusion in the lower limb has been hampered by poor reproducibility and a failure to reliably detect post-revascularization improvements in patients with critical limb ischemia (CLI).
Background: Evidence is lacking about the effectiveness of risk reduction interventions in patients with asymptomatic peripheral arterial disease.
Background: Genetic aortopathy (GA) underlies thoracic aortic aneurysms (TAA) in younger adults. Comparative survival and predictors of outcomes in nonsyndromic TAA (NS-TAA) are incompletely defined compared to Marfan syndrome (MFS) and bicuspid aortic valve (BAV).
Objective: To assess the rate of Vascular complications in steroid treated patients undergoing transfemoral aortic valve implantation (TAVI).
Background: Laser-assisted balloon angioplasty (LABA) has been shown to be more effective in achieving angiographic success for treatment for below knee peripheral artery disease (PAD) compared with balloon angioplasty alone(BA). However, long-term outcomes of LABA compared with BA for popliteal and infrapopliteal PAD are unknown.
We present a case of a patient with left lower extremity ischemic rest pain who initially underwent surgical profundaplasty requiring ligation of his superficial femoral artery (SFA). The patient developed continued rest pain due to diffuse disease of his profunda and inadequate collaterals. Endovascular intervention was therefore performed to the oversewn SFA. Retrograde left SFA access was obtained and the origin of the SFA was recanalized with true lumen re-entry using an ultrasound guided re-entry catheter. Angioplasty was performed at the origin of the SFA and self-expanding stents were deployed in the proximal and mid left SFA. Hemostasis at the distal left SFA access site was obtained by balloon inflation at the access site and manual compression. This case illustrates the feasibility of endovascular repair of a ligated SFA. © 2015 Wiley Periodicals, Inc.
Background: Current practice guidelines recommend surgical repair of large thoracic aortic aneurysms to prevent fatal aortic dissection or rupture, but limited natural history data exist to support clinical criteria for timely intervention.
Background: The AVERTTM Contrast Modulation System (AVERT) (Osprey Medical, MN) is designed to reduce contrast volume administration during angiography. The AVERT provides an adjustable resistance circuit which decreases the pressure head delivering contrast towards the patient. The AVERT has not been previously studied in patients undergoing peripheral digital subtraction angiography (DSA). The purpose of this study was (1) to evaluate contrast savings with the AVERT and (2) to evaluate the ability to generate clinically acceptable DSA images in the process. To better define the mechanism of action in the peripheral circulation, we also developed a bench model to study the effects of the AVERT on the hydrodynamics of contrast delivery.
Background: Endovenous recanalization of iliofemoral stenosis or occlusion with angioplasty and stent placement has been increasingly used to maintain long-term venous patency in patients with iliofemoral venous outflow obstruction. The purpose of this systematic review and meta-analysis was to determine safety and effectiveness of venous stent placement in patients with iliofemoral venous outflow obstruction.
