Primary repair of traumatic aortic rupture: a preferred approach.

Eighty patients with traumatic rupture of the thoracic aorta were treated. Seven patients died during the initial resuscitation. Forty-three patients underwent surgical repair using the clamp-and-sew technique; 14 patients had a heparin-bonded shunt placed, and 16 patients were repaired using cardiopulmonary bypass. An interposition Dacron graft was used in only 19 patients (26%). The last 32 consecutive patients underwent primary repair of the ruptured aorta. Overall mortality was 19.2% (14 of 80); 9 of 14 patients (64%) had laparotomies along with the aortic repair, and 13 of 14 patients (92%) had three or more associated major injuries. Paraplegia occurred in four cases (5.6%). Traumatic aortic rupture remains a difficult surgical problem. Primary repair, without graft interposition, is the preferred technique and can be accomplished even when the two aortic ends have retracted several centimeters.
