Abdominal aortic injury caused by blunt trauma is rare. We examined a 69-year-old-male with acute abdominal aortic occlusion due to a steering wheel injury in an automobile accident. At the time of the emergency operation, the infra-renal abdominal aorta was occluded with a complete transection of the intima and media, resulting in a flap formation and thrombosis. Aortoiliac arterial replacement was performed with a bifurcated Dacron graft. The postoperative course was complicated and included acute cardiac failure, respiratory distress, and myonephropathic metabolic syndrome. The patient gradually recovered, and to date remains well, 6 months after surgery.

A 74-year-old male was admitted to our hospital with a complaint of high fever, abdominal pain, and increasing anemia. Abdominal CT and angiography revealed a ruptured abdominal aneurysm. In an emergency operation the aneurysm was located between the superior mesentemic artery and the renal amtery. Aneurysmectomy and graft interposition were done. Bacteriological examinations of the exudate in retroperitoneal space confirmed the positive diagnosis of aneurysm due to Salmonella choleraesuis infection. The patient continues to remain well 10 months after the operation.
