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.
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.
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).
In selective TTAI patients for TEVAR, the length of proximal landing zone did not considerably influence the aorta size or needed further reintervention.
