Clinical improvement after extracranial venoplasty in multiple sclerosis.

Purpose: This study proposed to prospectively evaluate safety and clinical changes in outpatient endovascular treatment in patients with multiple sclerosis (MS) and chronic cerebrospinal venous insufficiency (CCSVI).

Materials And Methods: Two hundred fifty-nine patients with MS were followed with the Multiple Sclerosis Impact Scale (MSIS-29) before and for 1 and 6 months after treatment of extracranial internal jugular vein and azygos vein stenoses and occlusions using venous angioplasty, as well as stent placement in 2.5% of patients.

Long-term patency and clinical outcome of the Viabahn stent-graft for femoropopliteal artery obstructions.

Purpose: To assess the long-term patency of the Viabahn stent-graft after placement for the treatment of occlusive disease of the femoropopliteal artery (FPA).

Materials And Methods: Viabahn stent-grafts were placed into 87 limbs in 76 patients for the treatment of atherosclerotic occlusive disease of the FPA. Mean lesion length was 14.

The Nitinol SMART stent vs Wallstent for suboptimal iliac artery angioplasty: CRISP-US trial results.

Purpose: The Cordis Randomized Iliac Stent Project-US (CRISP-US) trial evaluated, with an equivalence design, the performance of the shape memory alloy recoverable technology (SMART) nitinol self-expanding stent and the stainless steel Wallstent for treating iliac artery disease after suboptimal percutaneous transluminal angioplasty (PTA).

Materials And Methods: This multicenter, prospective, randomized trial comprised 203 patients with chronic limb ischemia who received either the SMART stent (n = 102) or the Wallstent (n = 101) after suboptimal PTA. The primary equivalence end point was a composite of 9-month restenosis, 30-day death, and 9-month target vessel revascularization.

Endograft use in the femoral and popliteal arteries.

The results of infra-inguinal intervention for atherosclerotic occlusive disease have not changed dramatically in the last 15 years despite the advent of many different designs of uncovered stents. "Plain old balloon angioplasty" remains the treatment of choice for short lesions (<3 cm) with good morphologic characteristics. Stents have improved suboptimal angioplasty results somewhat, but results in longer lesions >5 cm have remained poor in most series.

Long-term results of ePTFE stent-graft versus angioplasty in the femoropopliteal artery: single center experience from a prospective, randomized trial.

Purpose: To describe a single-center experience as part of a U.S. multicenter prospective randomized trial of PTA versus percutaneous transluminal angioplasty (PTA)- and ePTFE (expanded polytetrafluoroethylene)-covered endoprosthesis placement for the treatment of superficial femoral artery (SFA) and proximal popliteal artery stenoses and occlusions.
