title: Drug eluting stents in the treatment of below the knee arterial occlusive disease.
abstract: The use of endovascular techniques for the treatment of occlusive arterial disease below the knee has gained widespread acceptance and is considered by many as the first line treatment for patients with critical limb ischaemia. Tibial angioplasty and stenting have a high rate of technical success and are relatively low risk procedures, which has widened their applicability to include treatment for the elderly and those with comorbidities unsuitable for open bypass surgery. Despite these advantages the durability of the percutaneous revascularisation remains inferior to that of open surgery for diffusely diseased arteries. In the search to improve their long term performance we have sought to investigate the role of coronary drug eluting stents (DES) in the tibial vasculature in the hope that they may reduce recurrent stenosis, the leading threat to interventional patency. Ample data now exists in the form of registries and randomised trials designed to evaluate the use of DES in the crural arteries below the knee. This article reviews this body of research, explores the use of these devices in more complex lesions, speculates on their future development and examines their cost-effectiveness.
