摘要
Restenosis and occlusion after endovascular .intervention of lower limb arteries remain the main problem in obtaining better results for patients with critical limb ischemia （CLI） and claudication. Improved angioplasty balloons, catheters, guide-wires, and operator skill have enabled 〉90% of stenotic and 〉80% of occluded arteries to be successfully cleared. However, percutaneous transluminal angioplasty （PTA） rarely results in sustained patency with most studies showing a 〈50% patency at 12 months.
