ABSTRACT

Objective:
Blunt thoracic aortic injury (BTAI) is a rare but fatal injury. BTAI has been treated surgically, but thoracic endovascular aortic repair (TEVAR) is used as a treatment option and has shown good results. The purpose of this study was to analyze the outcomes of patients with BTAI treated using TEVAR.
Method:
BTAI patients who had received TEVAR for five years were analyzed. We investigated injury severity score, aortic injury site, computed tomography findings and mortality.
Results:
We identified 17 patients, and all were diagnosed using computed tomography. Twelve patients received TEVAR as an emergency, and the remaining five patients received TEVAR delayed. The most common injury site was isthmus (82%), and the median injury severity score was 33. There were 15 cases with a BTAI grade of 3 and two cases with a BTAI grade of 4. The mortality rate was 11.8% (n=2).
Conclusion:
TEVAR is more meaningful because it is easier and faster and has fewer complications than thoracotomy in patients with traumatic aortic injury.
