Background: Approximately 20% of patients undergoing ankle brachial index testing for critical limb ischemia have noncompressible vessels because of tibial artery calcification. This represents a clinical challenge in determining tibial artery patency. We sought to identify the prevalence of tibial artery and pedal arch patency by angiography in these patients.
Background: A polymer-free peripheral paclitaxel-eluting stent (PES, Zilver PTX, Cook, IN) has shown to improve vessel patency after superficial femoral angioplasty. A new-generation fluoropolymer-based PES (FP-PES; Eluvia, Boston Scientific, MA) displaying more controlled and sustained paclitaxel delivery promise to improve the clinical outcomes of first-generation PES. We sought to compare the biological effect of paclitaxel delivered by 2 different stent-coating technologies (fluoropolymer-based versus polymer-free) on neointimal proliferation and healing response in the familial hypercholesterolemic swine model of femoral restenosis.
Objectives: The aim of this study was to investigate the clinical outcomes of pedal artery angioplasty (PAA) for patients with critical limb ischemia.
Objectives: The authors performed a meta-analysis of randomized controlled trials to compare the efficacy of initial endovascular treatment with or without supervised exercise training (SET) versus SET alone in patients with intermittent claudication.
Objectives: The aim of this study was to examine the frequency and clinical impact of different cessation patterns of dual-antiplatelet therapy (DAPT) after percutaneous coronary intervention with drug-eluting stents among patients with and those without diabetes mellitus (DM).
Objective: To assess the feasibility, safety, and clinical utility of a fast-track endovascular aneurysm repair (EVAR) protocol.
Purpose: Our aim was to evaluate the acute success and complication rates of the transradial and transulnar access for iliac artery stenting using sheathless guiding systems.
Given the marked increase in the number of patients with atrial fibrillation (AF) (1), more than 80% of acute limb ischemia (ALI) cases are now due to cardiac embolism associated with AF (2). Fogarty thrombectomy is the gold standard treatment of ALI.
Objectives: This study aimed to assess the optimal angiographic endpoint of endovascular therapy (EVT) for wound healing.
Abstract: Transcaval access has been used successfully for over 200 transcatheter aortic valve replacements, large-bore percutaneous left ventricular assist devices, and thoracic endovascular aortic aneurysm repairs. This review teaches how to plan transcaval access and closure based on computed tomography. The main planning goals are to: 1) identify calcium-free crossing targets in the abdominal aorta along with optimal fluoroscopic projection angles and level with respect to lumbar vertebrae; 2) identify obstacles such as interposed bowel or pedunculated aortic atheroma; 3) plan covered stent bailout; and 4) identify jeopardized vascular branches such as renal arteries that might be obstructed by bailout covered stents if employed. The aorta and inferior vena cava are segmented (sculpted) using an image reconstruction workstation and crossing targets are highlighted. Important measurements such as aortic lumen diameter and target distance from renal arteries, aortoiliac bifurcation, and right femoral vein puncture site are reported to assist the operator.
Objectives: The aim of this study was to investigate the clinical outcomes of pedal artery angioplasty (PAA) for patients with critical limb ischemia.
Objectives: The most effective first-line treatment between endovascular therapy and bypass surgery for patients with critical limb ischemia (CLI) is still not well defined. The primary aim of the interim analysis of CRITISCH (Registry of First-Line Treatments in Patients With Critical Limb Ischemia) was to compare both treatment options in a prospective confirmatory manner.
Objectives: The aim of this study was to assess the effectiveness of inferior vena cava (IVC) filter use among patients who develop recurrent symptomatic venous thromboembolism (VTE) on anticoagulant therapy.
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).
Drug-eluting stents (DES) are the default strategy for superficial femoral artery (SFA) intervention in 2015 because they have been evaluated in a large number of patients over a long follow-up period with outcomes superior to other treatment options. No other therapy can make that claim.
