Aortic dissection during cardiac operation is a rare but serious complication. Early detection and adequate repair is essential in this situation. A 69-year-old man in whom an aortic valve sparing operation for aortic root dilatation with aortic regurgitation had been begun, had an intraoperative aortic dissection 10 min after the start of right axillary artery perfusion. Intraoperative transesophageal echocardiography and direct epi-aortic echo revealed acute aortic dissection extending from the aortic root to at least the descending aorta. The dissection was successfully repaired by a Bentall operation and hemiarch replacement using hypothermic circulatory arrest, selective cerebral perfusion, and antegrade perfusion from an anastomosed graft.
