<b>Intentional Occlusion of the Left Subclavian Artery During Stent-Graft Implantation in the Thoracic Aorta:</b>Risk and Relevance

Abstract

Stent-graft-induced occlusion of the ostial LSA was tolerated by all patients without chronic functional deficit. In the absence of stenotic vertebral and/or carotid arteries and with a documented intact vertebrobasilar system, prophylactic transposition of the LSA is not required prior to intentional stent-graft occlusion of the LSA.
