Percutaneous transluminal angioplasty and stenting for iliac artery occlusive disease.
Atherosclerotic iliac artery stenoses respond well to simple balloon angioplasty and have the best results of all of the peripheral vessels. Nonetheless, initial technical failures occur in as many as 20% of patients, most of which can be salvaged with intravascular stenting, as can many of the potential complications; however, even though the initial technical success rates for stenting approach 100%, stenotic recurrences within stents are not infrequent. Whether promising new concepts, such as brachytherapy, gene therapy, and endoluminal grafting, will have a durable impact on the results of iliac angioplasty is yet to be seen. Meanwhile, the excellent results of endoluminal treatment of patients with iliac artery occlusive disease, combined with the relatively low risk for complications compared with surgical revascularization, ensure an enduring role for this modality of treatment and a diminution in the fraction of patients requiring surgery to correct their iliac artery occlusive disease.
