[Surgical treatment for recrudescent Stanford type A early closing dissection].

Two cases of recrudescent Stanford type A dissection were reported. They had non-opacified false channel on their initial CT and aortography. The first case was 65-year-old woman having a stable blood pressure and no chest pain after admission. However, recrudescent opacified false lumen was found at the mid-ascending aorta about three weeks later. She received ascending aortic replacement on 26th day after onset. The second case was 66-year-old woman having a unstable blood pressure and having periodic chest pain and back pain after admission. CT and angiography performed on the 41th day after onset revealed recrudescent descending aortic dissection and ulcer like projection at mid-ascending aorta. The ulcer like projection increased in size gradually. Ascending aorta replacement was performed on 110th day after onset. Two cases had a good post operative days. Some cases of Stanford type A early closing aortic dissection had recrudescent dissection later, even if they had a stable course after onset. Thus, careful follow up for long term is essential in these cases
