A 50-year-old man had undergone an initial original Bentall operation 19 years previously and replacement of the descending thoracic aorta 3 years previously. Computed tomography and an angiogram revealed a distal arch aneurysm and an ascending aortic aneurysm, neither of which had been detected 3 years previously. Detached anastomosis of the distal site and both coronary ostia were confirmed in the operation. Redo aortic root replacement and total arch replacement were performed successfully. His postoperative course was excellent.
