Endovascular interventions for the treatment of lower-extremity atherosclerotic disease have undergone a rapid course of development during the past 30 years. Balloon angioplasty is the most widely applied of these techniques and has been shown to yield excellent results, at least in the short and intermediate terms, in appropriately selected patients. The ideal candidate is one with a focal stenotic lesion of the iliac artery; this is also the type of patient in whom placement of an endoluminal stent, whether primarily or as an adjunct to balloon angioplasty, has been shown to be most effective. The initial enthusiasm for transluminal atherectomy of lower-extremity atherosclerotic lesions has met with some disappointing long-term results. It is now used mainly in conjunction with either or both of the above modalities in a select group of patients. Clearly, more controlled studies of all these techniques are needed to better define their exact indications and limitations in treatment of lower-extremity arterial disease.
