Endovascular treatment of aortic lesions involving branch vessels with multi-layer bare stents

Abstract

Aortic lesions involving branch vessels have always been a great challenge for vascular surgeons. Endovascular repair are growing to take place of traditional open repair for less invasion and lower complication rates. Despite rapid developments in endovascular instruments have been achieved in the last decade, and endovascular techniques such as fenestration stents have been applied in the treatment of aortic lesions involving branch vessels. However, endovascular repairing aortic lesions involving branch vessels remains being restricted by rigorous indication selection as well as requirements of advanced experiences and sophisticated skills. Recently, several studies about treating aortic lesion involving branch vessels with multi-layer bare stents have been reported, the primary results were encouraging and brought new visions for the management of such disease. More approving clinical evidences about the safety and efficacy of multi-layer stents are anticipated.
