Unruptured sinus of Valsalva aneurysm is a rare anomaly which may be acquired or congenital. We describe a case of a 64 year old man with aneurysms (left : 31 mm, non : 21 mm) of the coronary sinus. The Bentall operation was successfully performed and his postoperative course was uneventful. The histopathology of the aortic wall showed Takayasu's arteritis. Bentall surgery is a good choice for multiple aneurysms of the Valsalva sinus with aortitis.

A 37-year-old man who had received graft replacement of right iliac artery 20 years ago was admitted to our hospital because of massive intestinal hemorrhage. CT scan and angiogram showed a pseudoaneurysm originating from a graft anastomosis and the case was diagnosed as aorto-enteric fistula. Emergency operation was performed. Following aneurysmectomy and direct closure of split anastomosed portions, colostomy was performed in descending colon. Femorofemoral artery bypass was made as an extra-anatomical bypass. Fortunately, he has been successfully treated and is doing well now. The most important point for the rescue of cases of aneurysm-enteric fistula is to consider such cases of intestinal hemorrhage after the arterial graft replacement in the abdomen.
