The Emergency Operation for Ruptured Dissecting Limited Abdominal Aortic Aneurysm

The diagnosis of ruptured dissecting limited abdominal aortic aneurysm was made in four cases. The sex ratio (M/F) was 1/3, and mean age was 63.5 years (from 53 to 78yr). Only one of these cases die due to intraoperative bleeding. Other three cases were discharged from our hospital. Intraluminal proximal anastomosis after fixed dissected aortic wall due to mattress suture and end to end anastomosis with reinforcement by Teflon felt were good results. The one case who was anastomosed simple intraluminal method has pseudoaneurysm in the proximal portion. It is important to diagnose preoperatively dissection and to make end to end anastomosis with Teflon felt.
