Abstract
Bare-metal stents have been utilized as an alternative therapy for aorto–iliac occlusive disease. Although, these stents perform well in TransAtlantic Inter-Society Consensus (TASC) A and B lesions, their patency remains inferior to surgical bypass in TASC C and D lesions, requiring reinterventions or surgical bypass in the future. Covered stents (balloon-expandable and self-expanding) are introduced with the intention to achieve better long-term patency and reduce reintervention, especially in complex aorto–iliac lesions. Multiple recent studies have demonstrated improved long-term patencies in a covered stent group in comparison with bare-metal stents in simple, as well as complex, lesions. Based on current data, the use of covered stents will definitely be beneficial, especially in TASC C and D lesions.
