PURPOSE: Thoracic endovascular aortic repair (TEVAR) for traumatic thoracic aortic injury (TTAI) reports short-term benefits. However, long-term durability and the need of reintervention remain unclear. Here, we determined mid-term outcome of TEVAR for TTAI and investigated the influence of the length of proximal landing zone on aorta. METHODS: Between October 2009 and February 2018, 69 patients diagnosed TTAI and 42 included patients underwent TEVAR. patients were divided into two groups by the length of proximal landing zone; ≤ 20 mm and > 20 mm. The primary endpoint was success and survival rate, and the secondary endpoint was the increase of aorta size and the need of reintervention. RESULTS: The mean follow-up period was 47.9 ± 29.6 months and 100% success rate. No endoleaks or additional reinterventions during the follow-up period. The cumulative survival of all-cause death was 90.5 ± 2.3%, 85.7 ± 4.1% and 61.7 ± 8.4% at 1, 5 and 7 years, respectively. There was no statistically significant difference in the increase of aorta size due to the length of the proximal landing zone (p = 0.65). CONCLUSION: In selective TTAIpatients for TEVAR, the length of proximal landing zone did not considerably influence the aorta size or needed further reintervention.
