Abstract
Thoracic aorta injury caused by blunt chest trauma is often fatal. A 26-year-old male with bilateral pneumohemothorax and disruption of the thoracic descending aorta due to a traffic accident was referred to our hospital. The chest X-ray film and CT scanning showed neither mediastinal widening nor periaortic hematoma. Three weeks after admission, aortography revealed flap formation at the aortic isthmus. Two months after trauma, we replaced the injured aorta with a vascular prosthesis using a centrifugal pump. Pathological examination showed separation of a medial layer of the aorta. His postoperative course was uneventful.
