Purpose: To compare the outcomes of thoracic endovascular aortic repair (TEVAR) with those of open repair for descending thoracic aortic aneurysms (DTAA). Materialsand Methods: We compared the outcomes of 114 patients with DTAA and proximal landing zones 3 or 4 after TEVAR to those of 53 patients after conventionalopen repairs. Thirty-day and late mortality were the primary endpoints, and early morbidities, aneurysm-related death, and re-intervention were the secondary endpoints. Results: The TEVAR group was older and had more incidences of dissectinganeurysm. The mean follow-up was 36±26 months (follow-up rate, 97.8%). The 30-day mortality in the TEVAR and open repair groups were 3.5% and 9.4% (p=0.11). Perioperative stroke and paraplegia incidences were similar between the groups [5.3% vs. 7.5% (p=0.56) and 7.5% vs. 3.5% (p=0.26), respectively]. Respiratoryfailure occurred more in the open repair group (1.8% vs. 26.4%, p<0.01). The incidence of acute kidney injury requiring dialysis was higher in the open repair group (1.8% vs. 9.4%, p<0.01). The cumulative survival rate was higher in the TEVARgroup at 2 to 5 years (79.6% vs. 58.3%, p=0.03). The free from re-intervention was lower in the TEVAR group (65.3% vs. 100%, p=0.02), and the free from aneurysm-related death in the TEVAR and open repair groups were 88.5% and 86.1% (p=0.45). Conclusion: TEVAR is safe and effective for treating DTAAs with improvedperioperative and long-term outcomes compared with open repair.
