Abstract
Female sex has been associated with decreased mortality following blunt trauma, but whether sex influences outcomes of thoracic endovascular aortic repair (TEVAR) for traumatic blunt thoracic aortic injury (BTAI) is unknown.In this retrospective study of a prospectively maintained database, the Vascular Quality Initiative (VQI) registry was queried from 2013-2020 for patients undergoing TEVAR for BTAI. Univariate Student's t-tests and chi-squared tests were performed, followed by multivariate logistic regression for variables associated with inpatient mortality.211 (26.2%) of 806 patients were female. Female patients were older (47.9 vs. 41.8 years, p<0.0001) and less likely to smoke (38.3% vs. 48.2%, p=0.044). Most patients presented with grade III BTAI (54.5% female, 53.6% male,), followed by grade IV (19.0% female, 19.5% male). Mean Injury Severity Scores (30.9 + 20.3 female, 30.5 + 18.8 male) and regional Abbreviated Injury Score did not vary by sex. Postoperatively, female patients were less likely to die as inpatients (3.8% vs 7.9% , p=0.042) and to be discharged home (41.4% vs. 52.2%, p=0.008). On multivariate logistic regression, female sex (OR 0.05, p=0.002) was associated with reduced inpatient mortality. Advanced age (OR 1.06, p< 0.001), postoperative transfusion (OR 1.05, p=0.043), increased Injury Severity Score (OR 1.03, p=0.039), postoperative stroke (OR 9.09, p= 0.016), postoperative myocardial infarction (OR 9.9, p=0.017), and left subclavian coverage (OR 2.7, p= 0.029) were associated with inpatient death.Female sex is associated with lower odds of inpatient mortality following TEVAR for BTAI, independent of age, injury severity, BTAI grade, and postoperative complications. Further study of the influence of sex on post-discharge outcomes is needed.
