Abstract:Objective： To investigate the method of diagnosis and treatment of patients with intestinal bleeding after aortic reconstruction. Methods：The clinical data of 6 patients who had intestinal bleeding after aortic reconstruction from 1995 to 2006, including the etiology, clinical manifestations, imaging data, diagnosis and operative findings, were analysed retrospectively. Results：All cases underwent repair of aortoenteric fistulas and partial enterectomy after aortic occlusion under general anesthesia. The cause of intestiral bleeding in all cases was abdominal aorto-enteric fistula. One case died from multiple organ system failure on the 11th day after operation. Five cured cases were followed-up for 1~10 years. The results showed that 3 cases were alive longer than 5 years and 2 cases died from acute myocardiac infaction and intracerebral hemorrhage more than 1 year after operation respectively. Conclusions：The correct diagnosis of aortoenteric bleeding may be confirmed by combining clinical manifestation with imaging data. Repair of the aortoenteric fistula is a rational and reliable method in treating this complicated illness.
