Surgical treatment of traumatic thoracic aorta rupture: a 7-year experience.
OBJECTIVE
Traumatic aortic rupture is highly lethal and an ongoing therapeutic challenge. We review our 7-year experience with traumatic aortic disruption.


METHODS
We treated 12 cases of traumatic rupture of the thoracic aorta (TRTA) from December 1994 to June 2001 at our institution. Of these, 9 were male, and the average age 26 years. Injuries were caused by traffic accidents in 9 cases and falls in 3. Contrast-enhanced helical computed tomography was used to diagnose10 cases and digital subtraction angiography to diagnose 2 at other hospitals. Six of 12 (50%) disruptions were located in the aortic isthms. All surgery was conducted under cardiopulmonary bypass. A percutaneous cardiopulmonary support system (heparin-bonded artificial lung and centrifugal pump) was used in 6 cases since 1998.


RESULTS
Among the 12 patients, 6 had early surgical repair within 2 days after the accident, and all survived free of neurological problems. Six other had repair delayed more than 2 days and all were doing well.


CONCLUSIONS
Immediate repair of aortic lesions should be the rule because the majority of deaths from TRTA occur within 24 hours. We believe, however, that immediate surgery may not be necessary for some patients with severe, multiple associated lesions who survive initial traumatic aortic disruption of the aorta.
