[A case of complete circumferential aortic rupture due to blunt chest trauma].

A case of complete circumferential rupture of the thoracic aorta due to blunt chest trauma is presented. A 30-year-old man was admitted after a traffic accident. The admission chest X-ray film demonstrated mediastinal widening. About 6 hours after the traffic accident, chest CT scanning demonstrated mediastinal hematoma, left pleural effusion and partial aortic dissection. Diagnoses of aortic rupture and liver injury were made, and surgery for the thoracic aorta was performed immediately. The aorta was found to be completely disrupted for the length of 2 cm, and a vascular prosthesis was interposed between the two ends of the aorta under partial cardiopulmonary bypass. We conclude that the enhanced chest CT scanning is helpful for diagnosis, and that if other organ injuries are not severe, the emergency operation should be performed.
