title: [Strategy for thrombosed type A acute aortic dissection].
abstract: The surgical treatment for thrombosed type A aortic dissection is controversial. We treated 15 cases (28.8%) with thrombosed type A acute aortic dissection among 52 cases of all type A acute aortic dissection during past 7 years and 8 months. Nine cases was treated conservatively and 6 cases received emergent operation due to cardiac tamponade, shock, and ulcer-like projection (ULP) in the ascending aorta (> 50 mm). In the group of conservative therapy, 2 cases in which the ascending aorta was enlarged (54, 60 mm), was converted to operation in the acute phase because of further enlargement of ascending aorta and increase of cardiac effusion. The other patients (aortic diameter: 40-46 mm) who received conservative therapy were well controlled by medical therapy in the early and late phase except 1 who died suddenly in the follow-up. There was no mortality and late death in the operated patients. From these results, we conclude that thrombosed type A aortic dissection in which the diameter of ascending aortic aorta is larger than 50 mm, have cardiac tamponade and ULP in the ascending aorta might needs operation.
