Intentional coverage of the left subclavian artery during endovascular repair of traumatic descending thoracic aortic transection

Coverage of the LSA during TEVAR for traumatic aortic injuries appears to be a feasible, safe method for extending the endograft landing zone without increasing the risk of paraplegia, stroke, or left arm ischemia. Left vertebral artery diameter can be used to identify patients at risk for postoperative left arm ischemia.
