Posttraumatic infrarenal abdominal aortic pseudoaneurysm.

Posttraumatic abdominal aortic pseudoaneurysm is a rare lesion. To date, fewer than 30 cases have been reported in the literature, with most of those cases involving the suprarenal aorta. Infrarenal posttraumatic abdominal aortic pseudoaneurysm following abdominal trauma has been reported in only 6 other cases. We observed such a lesion in a 62-year-old man 15 years after blunt abdominal trauma inflicted in a car accident. Back pain was the presenting symptom. Resection and Dacron graft interposition were performed without postoperative morbidity.
