Surgical management of traumatic aortic disruption.

BACKGROUND: Acute traumatic disruption of the descending thoracic aorta is a life-threatening injury that requires emergent operative intervention. From May 1988 to August 1996, 27 patients have undergone surgical repair at our institution.

METHODS: Diagnosis of aortic disruption was confirmed in all patients by aortogram prior to aortic repair. A Gott shunt was used in 24 patients (89%) and partial femoral-femoral bypass in 1 patient (4%) for distal perfusion. A clamp-and-sew technique was used in 2 patients (7%).

RESULTS: Mean aortic clamp time was 44 +/- 3 minutes (range 22 to 80 minutes) in patients with distal perfusion via a Gott shunt. One patient (4%) died within 30 days of aortic repair due to multisystem organ failure. Paraplegia occurred in 1 patient (4%).

CONCLUSIONS: With a disciplined, diagnostic and surgical approach for patients with traumatic disruption of the descending thoracic aorta, it is possible to achieve excellent outcomes. The use of a Gott shunt is a simple and effective method for distal perfusion during the repair of traumatic aortic rupture.
