title: A case of abdominal aortic injury caused by a traffic accident.
abstract: A 30-year-old man was injured when the large motorcycle he was riding crashed into a power pole. Upon arrival at our institution, the patient complained of abdominal pain; blood pressure at admission was 160/70 mmHg, and the heart rate was 112 bpm. Abdominal ultrasonography showed a small collection of fluid in Morrison's pouch. A chest X-ray film showed a right rib fracture. Multidetector computed tomography (MD-CT) revealed pleural effusion, a hepatic lesion, and a dissection of the abdominal aorta distal to the renal artery. Because of the complicated intraluminal injuries, the insertion of a stent graft was difficult. On the 34th day after injury, elective surgery was performed. Because dissection of the lumen was observed, the vessel was replaced with an artificial graft. Medial degeneration of the aorta wall was not observed upon pathological examination, and no degenerative disorders have occurred. The postoperative progress was favorable, and the patient was discharged from hospital.
