Endovascular repair of traumatic aortic transection.

The present study reports a single center experience and mid-term results of endovascular repair of acute aortic traumatic transection on an emergency basis, instead of open surgical management. From January 2005 to December 2008, 13 cases of traumatic aortic transection with serious comorbidities, which underwent repair with thoracic stent grafts at our institution, were reviewed. The mean patient age was 32.5+/-7.8 years. During the follow-up period of 25.5+/-12.8 months, 12 patients were alive and one patient died of associated injuries. There were no intraoperative deaths, no incidence of paraplegia and no procedure-related mortality. The blood loses during the procedure were minimal. The thoracic aortic grafts were larger than the thoracic aorta by 12.4+/-5.7%. Five cases required complete or partial coverage of the left subclavian artery. There were two cases of graft collapse, which were successfully treated by endovascular reintervention. Our results suggest that this approach is safe, effective and can be performed with low rates of morbidity and mortality, especially in respect of patients with multiple injuries. Although initial results are encouraging, close long-term follow-up and technical improvements of the stent grafts are required.
