A 62-year-old woman was referred to our hospital for treatment of hemolytic anemia 10 years after total arch replacement for acute aortic dissection. The cause of hemolysis was confirmed to be mechanical damage of red blood cells at the kinked graft. Because aortic valve regurgitation and occlusion of the left subclavian artery were also found, resection of the kinked graft, aortic valve replacement and reconstruction of the left subclavian artery were carried out concomitantly at reoperation. Her postoperative course was uneventful, and hemolysis resolved soon after the operation.
