Dissection of the abdominal aorta associated with traumatic aneurysms of the iliac vessels. Case report.

Dissection of the abdominal aorta without an associated thoracic dissection is uncommon. It is usually associated with blunt abdominal trauma and commonly presents early with aortic occlusion. A case is presented where abdominal aortic dissection presented two months after lower abdominal trauma. It is suggested that the initiating event in this case was injury to the iliac vessels.
