[A case of acute dissecting aneurysm associated with AAE (annuloaortic ectasia) necessitating coronary bypass surgery].

We report a successful surgical treatment of acute dissecting aneurysm of the ascending aorta associated with annuloaortic ectasia. The patient was a 29-year-old male, who was admitted to the hospital 5 hours after the onset of anterior chest pain. Aortography revealed acute dissection of the ascending aorta (DeBakery type I) with AAE. The intimal tear surrounding the right coronary ostium was found. The procedure between the right coronary artery and aorta (replaced artificial graft) using saphenous vein graft was also required in addition to Bentall's operation. Postoperative studies revealed disappearance of the dissection, patency of the bypass graft. The postoperative course was uneventful and the patient is in active life two years after operation.
