Nonpenetrating trauma of the abdominal aorta with partial vessel occlusion: report of two cases.
Two cases of blunt trauma of the abdominal aorta are reported. In both there was lacreation of the intima and development of intimal flaps with only partial occlusion of the aorta. Immediate recognition in one allowed prompt repair of injured tissue. Delayed recognition in the other, while not life-threatening, did prolong disability  and did necessitate vascular tissue replacement with prosthetic graft. Audible bruit and palpable thrill are diagnostic signs that, if sought for in the emergency room and operating room examinations of the traumatized abdomen, will yield early recognition of this lesion.
