Objective: Endovascular stent-graft repair holds promise for treating traumatic injuries of the descending thoracic aorta. The durability of this approach, however, remains unknown. The objective is to evaluate the mid-term results of stent-graft repair of chronic traumatic aneurysms of the descending thoracic aorta. Methods: Between 1993 and 2000, endovascular repair of the descending thoracic aorta with first (custom-fabricated) and second-generation (commercial) stent-grafts was performed in 15 patients (mean age 54±13 years) at an average of 18±14 years after the injury. Because of comorbidities, 4 patients (27%) were judged not to be reasonable surgical candidates for conventional open surgical approach. Follow-up was 100% complete and averaged 55±29 months. Results: Stent-graft deployment was successful in all without need for surgical conversion. One patient died early postoperatively. No neurologic complications occurred. Two patients had a primary endoleak, one of them was successfully treated before discharge. Actuarial survival estimates at 1 and 6 years were 93±6% and 85±10%. Actuarial freedom from reintervention on the descending thoracic aorta was 93±6% and 70±15% at 1 and 6 years, respectively. Actuarial freedom from treatment failure (a conservative, all-encompassing performance indicator including endoleak, device mechanical fault, reintervention, late aortic-related death, or sudden, unexplained late death) at 1 and 6 years was 87±8% and 51±15%. Conclusions: Stent-grafting is safe in selected patients with chronic traumatic aneurysms and associated with satisfactory - but not optimal - mid-term durability. Serial follow-up surveillance imaging is mandatory to detect late stent-graft complications. Younger, good risk patients should be offered conventional open operation, reserving stent-grafting for those who are at prohibitive operative risk or who have limited life expectancy.
