Abstract: We experienced two rare cases of acute aortic dissection with leg ischemia after Y graft repair of the abdominal aortic aneurysma. Case 1 was a 63-year-old woman who had received Y graft repair at age 55, and case 2 was a 28-year-old man with Marfan's syndrome who received a Y graft repair at age 21. Both patients sustained DeBakey type I dissections terminating at the suture line of the Y graft and had symptoms of acute arterial occlusion of bilateral lower extremities. Emergency operation was performed 8 hours after onset in case 1 and 6 hours after in case 2. Case 1 could not be weaned from cardiopulmonary bypass because of intraoperative rupture and acute heart failure, but case 2 underwent successfully aortic root replacement and total arch replacement under selective cerebral perfusion.
