Definition

Usually in elderly patients after graft repair of abdominal aortic aneurysm but retroperitoneal disease can be the setting; dramatic amount of upper GI bleeding is the hall mark of this lethal complication; often fever, malaise and retroperitoneal symptoms including pain of penetrating ulcer disease, give scant warning; Endoscopy with long scfope lets you view the duodenum where the large clot is seen; CT scan of abdomen is abnormal but endoscopic ultrasound just diagnosis the leaking graft and substrate for disaster;
