Traumatic Dissection of the Ascending Aorta Complicated by Multiple Injuries Following a Traffic Accident.

Trauma to the ascending aorta may progress to a cardiac tamponade, which is often life-threatening. Here, we report on a case of traumatic dissection of the ascending aorta, complicated by multiple injuries. A 24-hour follow-up period was provided to evaluate the traumatic bleeding, and a large tear that extended over three-quarters of the circumference of the aortic intima was identified. An ascending aorta and partial arch replacement were successfully performed. The timing of cardiopulmonary bypass surgery in cases of multiple traumas must be sufficiently flexible to accommodate the condition of each patient, considering the risk of sudden hemodynamic collapse.
