OBJECTIVES The hypothesis that endovascular treatment with covered stents has equal risks but higher efficacy than bare-metal stents (BMS) in long femoropopliteal artery disease was tested. BACKGROUND Although endovascular treatment of short superficial femoral artery lesions revealed excellent results, efficacy in long lesions remains unsatisfactory. (More)
PURPOSE To report a prospective study to evaluate safety, effectiveness, and midterm patency of self-expanding stent-grafts in patients with femoropopliteal occlusive disease. MATERIALS AND METHODS Sixty-three Hemobahn stent-grafts were used in 52 patients for treatment of medium- or long-segment (>3 cm) occlusions (82.7%) and stenoses (17.3%) of the(More)
PURPOSE To determine the safety and efficacy of total percutaneous access closure for endovascular aortic aneurysm repair with a suture-mediated preclosing technique. MATERIALS AND METHODS One hundred thirty-two femoral access sites in 70 patients who underwent endovascular aortic aneurysm repair were closed percutaneously with off-label use of two F-6(More)
PURPOSE To evaluate the long-term efficacy and integrity of the PROTEGE EverFlex stent in superficial femoral artery (SFA) lesions in symptomatic patients with peripheral artery disease (PAD). METHODS A prospective, multicenter, nonrandomized study enrolled 151 subjects (111 men; mean age 67.8 years, range 42-93) undergoing percutaneous treatment of de(More)
PURPOSE To develop a method for generating realistic pulmonary nodules that equal small pulmonary metastases and granulomas. MATERIALS AND METHODS A total of 70 artificial lesions were introduced into 5 inflated porcine lungs inside a dedicated chest phantom by high pressure injection of a fat-wax-Lipiodol mixture and scanned with 16-slice computed(More)
PURPOSE To assess the effectiveness, technical aspects, handling, and safety of the micromesh Roadsaver Carotid Artery Stent in the treatment of atherosclerotic carotid artery stenosis and tandem lesions in ischemic stroke patients. METHODS Seven patients (5 men; mean age 75±11.4 years, range 53-86) suffering from symptomatic internal carotid artery (ICA)(More)
AIMS The aim of this study was to evaluate the 30-day clinical outcome of treatment using the Roadsaver carotid stent in non-consecutive subjects at high risk for carotid endarterectomy requiring revascularisation. METHODS AND RESULTS The CLEAR-ROAD study is a prospective, multinational, single-arm, physician-initiated study planned to include 100(More)
Interventional Radiology (IR) is an essential part of modern medicine, delivering minimally invasive patient-focused care, which has been proven to be safe and effective in both elective and emergency settings. The aim of this document is to outline the core requirements and standards for the provision of Interventional Radiological services, including(More)
PURPOSE To investigate the 2-year technical and clinical results of primary nitinol stent placement in comparison with percutaneous transluminal angioplasty (PTA) in the treatment of de novo lesions of the popliteal artery. METHODS The ETAP study (Endovascular Treatment of Atherosclerotic Popliteal Artery Lesions: balloon angioplasty vs. primary stenting;(More)
We (1) evaluated the effectiveness of different media on the detachment of endothelial cells (ECs) from a catheter brush (Cragg thrombolytic catheter system) that was previously used for endothelial cell abrasion in 10 cm human umbilical vein (HUV) segments; (2) tested the practicability of endovascular catheter brush abrasion followed by EC detachment from(More)
