Abstract
OBJECTIVE
To investigate the long-term reinterventions of thoracic endovascular repair (TEVAR) after blunt traumatic aortic injury.
METHODS
MEDLINE, EMBASE, and Cochrane databases were interrogated until June 2021. Inclusion criteria were blunt traumatic aortic injury treated with TEVAR and mean follow-up of more than 60 months. A systematic review was conducted and data were pooled using a random effects model of proportions applying the Freeman-Tukey transformation. Late reintervention was the primary outcome. Secondary outcomes were procedure-related complications (endoleak, in-stent thrombosis, occlusion, infolding/collapse, bird-beak, migration, and left arm claudication), overall and aortic-related mortality, and aortic diameter changes.
RESULTS
Eleven studies with a low quality assessment were included. Four hundred eight patients were collected and the 389 surviving more than 30 days were included. The mean follow-up was 8.2 years (95% confidence interval [CI], 5.7-10.8; I2 = 40.2%). Late reintervention was 2.1% (95% CI, 0.6-3.9; I2 = 0.0%; 11/389 cases) with 0.1% (95% CI, 0.0-1.2; I2 = 0.0%; 3/389) occurring after 5 years. Bird-beak was identified in 38.7% (95% CI, 16.4-63.6; I2 = 86.6%). Left arm claudication occurring after 30 days was 3.1% (95% CI, 0.1-8.6; I2 = 26.9%; 11/140 cases). In-stent thrombosis was 1.9% (95% CI, 0.1-5.2; I2 = 51.8%; 11/389 cases). Endoleak was 0.5% (95% CI, 0.0-1.9; I2 = 0.0%; 5/389 cases). Infolding, occlusion, and migration were reported in 2 of 389, 1 of 389, and 0 of 389 patients, respectively. Overall late survival was 95.6% (95% CI, 88.1-99.8; I2 = 84.7%; 358/389 patients) and only one patient accounted for aortic related mortality. The increase in proximal and distal aortic diameters was estimated at 2.7 mm (95% CI, 1.2-4.3; I2 = 0.0%) and 2.5 mm (95% CI, 1.1-3.9; I2 = 0.0%), respectively.
CONCLUSIONS
TEVAR demonstrates remarkably good long-term results and reinterventions are rarely required. Aortic reinterventions tend to occur within the first and after the fifth year.
