However, the long-term outcomes of endovascular repair and the risks of left subclavian coverage remain unclear. METHODS From April 2001 to August 2018, 33 patients with blunt traumatic thoracic aortic injury underwent endovascular repair in our institution. A follow-up computed tomography and a clinical examination were performed before discharge and at 1 month, and yearly or every 2 years thereafter. RESULTS The mean age was 45 ± 19 years. The technical success rate was 100%. Complete coverage of the left subclavian artery (LSCA) was performed in 20 patients (60.6%). Among 20 patients with coverage of the LSCA, revascularization was performed in 1 patient. No in-hospital deaths occurred. The clinical follow-up rate was 97%, with a mean period of 7 years and a maximum of 18 years. The survival rates were 100% at 1 year, 95% at 5 years and 88.7% at 10 years after the event. Among the 5 patients (20%) who developed neurological complications, 1 who had undergone implantation of a 200-mm long stent graft and LSCA coverage without revascularization developed paraplegia during the long-term follow-up. CONCLUSIONS This study demonstrates that the endovascular treatment of blunt traumatic thoracic aortic injury is a safe and effective therapeutic method over a long-term follow-up period. LSCA coverage and long stent graft placement might be indications for revascularization to prevent spinal cord injury.
