[Thoracic Endovascular Aortic Repair for Residual Aneurysm after Operation of Acute Stanford type B Aortic Dissection;Report of Two Cases].

Abstract We performed thoracic endovascular aortic repair (TEVAR) for residual aortic aneurysm after operation of acute Stanford type B aortic dissection in 2 cases. In case 1, a 53-year-old male who had undergone operation for acute type III a aortic dissection in 2005, underwent TEVAR for ulcer-like projection at distal re-entry site. In case 2, a 55-year-old male who had undergone graft replacement for acute type III b aortic dissection in 2007, underwent TEVAR because the size of the anastomotic aneurysm was increased to 7 cm. Their postoperative courses were satisfactory. We think TEVAR is useful for residual aneurysm after type B aortic dissection surgery because it is less invasive and brings better results.
