Background: The objective of the RANGER II SFA long lesion cohort analysis was to evaluate the safety and effectiveness of the Ranger drug-coated balloon (DCB) in patients with lesion lengths greater than 100 mm.
Methods: Patients from the RANGER II SFA randomized controlled trial and long balloon sub-study were included in the long lesion cohort if their baseline lesion measurement was > 100 mm and if they had been treated with a RANGER DCB. Patients had symptomatic lower limb peripheral artery disease and Rutherford classification 2-4 symptomatology.
Objectives: This study sought to evaluate the safety and effectiveness of the Ranger drug-coated balloon (DCB) (paclitaxel dose density 2 μg/mm) for treating superficial femoral artery or proximal popliteal artery lesions.
Background: Paclitaxel-coated balloon treatment prevents reinterventions, but dose and coating characteristics differ among balloons and necessitate discrete confirmation of safety and effectiveness.
Methods: Patients with symptomatic lower limb ischemia (Rutherford classification 2 to 4) were randomized 3:1 to treatment with the Ranger DCB or standard percutaneous transluminal angioplasty (PTA).
Background: This clinical trial aims to evaluate the outcome (up to 24-months) of the treatment of in-stent restenotic or reoccluded lesions in the femoropopliteal arteries, by comparing the treatment of the GORE VIABAHN Endoprosthesis with PROPATEN Bioactive Surface (W. L. Gore & Associates, Flagstaff, AZ, USA) with a standard PTA treatment.

The presence of accessory veins may play an important role in the non-maturing fistula. Several surgical and endovascular techniques are described to deal with this problem.
View Article and Find Full Text PDFEndovascular options are increasingly recognized as primary treatments for lower extremity peripheral arterial disease inadequately responsive to noninvasive therapy. Options include balloon angioplasty and stent implantation, and newer technologies incorporate drug coatings to prevent restenosis and reduce the need for reintervention. The Eluvia drug-eluting vascular stent system (Boston Scientific, MA, USA) was designed with a biocompatible fluoropolymer coating to allow for drug elution over time.

Background: DCB coatings differ in excipients, paclitaxel dose, and coating morphologies. Due to these differences, a class effect with DCBs has not been demonstrated.
Purpose: To report the 3-year results of the MAJESTIC first-in-human study of the Eluvia Drug-Eluting Vascular Stent System for treating femoropopliteal artery lesions.
Methods: The prospective, single-arm, multicenter clinical trial enrolled 57 patients with symptomatic lower limb ischemia (Rutherford category 2, 3, or 4) and lesions in the superficial femoral artery or proximal popliteal artery. Mean lesion length was 70.
Objectives: The SuperNOVA trial was designed to evaluate performance of the Innova Vascular Self-Expanding Stent System (Boston Scientific, Marlborough, MA) for treating lesions in the femoropopliteal arteries.
Methods: Patients with chronic lower limb peripheral artery disease (Rutherford category 2, 3, or 4) and atherosclerotic lesions in the native superficial femoral and/or proximal popliteal artery (lengths 30-190 mm) were enrolled in this single-arm, multinational study. Major adverse events (MAEs) were defined as all-cause death through 1 month, target limb major amputation, and target lesion revascularization (TLR).
Objective: Bioresorbable stents are an emerging technology in the endovascular treatment of femoropopliteal lesions. They address the issue of leaving permanent stents in the treated arterial segment that are only temporarily needed to treat dissection or recoil. The REMEDY stent (Kyoto Medical Planning Co, Kyoto, Japan) was the first commercially available biodegradable scaffold for peripheral use.

Methods: The prospective, single-arm, multicenter trial (clinicaltrials.gov identifier NCT01820637) enrolled 57 patients (mean age 69±9 years; 47 men) with chronic lower limb ischemia referable to de novo or restenotic lesions in the native superficial femoral and/or proximal popliteal arteries.
Purpose: To evaluate the short- and midterm outcomes of the Viabahn endoprosthesis with Propaten Bioactive Surface vs. standard balloon angioplasty for treatment of in-stent restenosis in the superficial femoral artery.
Methods: Between June 2010 and February 2012, 83 patients with superficial femoral artery in-stent and Rutherford category 2 to 5 ischemia were enrolled at 7 sites participating in this prospective randomized controlled study (RELINE; ClinicalTrials.
Background: A novel self-expanding drug-eluting stent was designed to release everolimus 225 μg/cm(2) to prevent restenosis following peripheral arterial intervention. The purpose of this study was to measure the pharmacokinetic profile of everolimus following stent implantation.
Methods: One hundred four patients with symptomatic peripheral arterial disease underwent implantation of everolimus-eluting stents in the femoropopliteal arteries.
Purpose: To report the 2-year results of the MELODIE trial, which evaluated the safety and effectiveness of the balloon-expandable Express LD Vascular stent for the treatment of atherosclerotic iliac artery disease.
Methods: This prospective, multicenter, single-arm trial enrolled 151 patients (113 men; mean age 60.1±8.
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 novo, restenotic, or reoccluded SFA lesions between August 11, 2006, and June 26, 2007.
Objective: Several prosthetic materials have been used for femoropopliteal bypass grafting in patients with peripheral vascular disease in whom a venous bypass is not possible. Expanded polytetrafluoroethylene (ePTFE) is the most commonly used, but patency results have not always equaled those achieved with vein, especially in below-knee reconstructions. This study assessed the performance of a new heparin-bonded ePTFE vascular graft that was designed to provide resistance to thrombosis and thereby decrease early graft failures and possibly prolong patency.

Methods: In the period from October 2001 to May 2002, 100 patients (60 men; mean age 72 years, range 48-90), 69 symptomatic with >or=50% internal carotid artery (ICA) stenosis and 31 asymptomatic with >or=70% stenosis were scheduled for carotid stenting with cerebral protection provided by the FilterWire EX system. Satisfactory performance of the filter was defined as effectiveness in preventing intraprocedural embolic events shown by visible debris in the filter and unchanged neurological status assessed by an independent neurologist.
