Repair of Late Retrograde Type A Aortic Dissection After TEVAR: Causes and Management.

One of the most feared complications of thoracic endovascular aortic repair (TEVAR) and hybrid arch repair is retrograde type A aortic dissection (RTAD). More than two-thirds of RTAD occurs in the immediate postoperative period and first postoperative month. In presentations beyond that point, progression of the native aortopathy must be considered. We report a late presentation of an RTAD seven months after hybrid repair of an aortic intramural hematoma with an ulcer-like projection, and review the causes and management of this TEVAR complication.
