New techniques and developments of stenting for infrainguinal arterial occlusive disease: are the results any better than balloon angioplasty alone?

Infrainguinal occlusive disease is a complex problem necessitating the cooperation of both medical and surgical therapies to aid limb salvage and alleviate symptoms. Endovascular therapies are varied, with no treatment clearly outweighing the other in terms of efficacy and durability. Angioplasty for focal stenosis has gained ground as the treatment of choice when indicated. There has also been a rapid evolution in stent technology, from early stainless steel wall stents to today's drug eluting nitinol stents. In this article, we examine the literature on these new technologies and treatment options and make recommendations based on the best data available.
