[Elderly patient with acute type A aortic dissection; report of a case].

A 93-year-old woman complained of severe back pain. Computed tomography (CT) and echocardiography revealed acute type A aortic dissection with enlargement of the ascending aorta, moderate aortic regurgitation and cardiac tamponade. Despite her age, the patient was able to support herself, and she and her family desired to have a surgical treatment. Therefore she was referred to our hospital immediately and underwent an emergent ascending aortic replacement using a 28mm woven Dacron graft under deep hypothermic circulatory arrest. Postoperative course was uneventful, and the patient was discharged from our hospital on the 34 th postoperative day in good condition.
