BackgroundCommon and external iliac artery injuries (IAI) portend significant morbidity and mortality. The goal of this study was to examine the impact of mechanism of injury and type of repair on outcomes and identify the optimal repair for patients with traumatic IAI using a large, national dataset.Study DesignPatients undergoing operative repair for IAI were identified from the Trauma Quality Improvement Program database during a 5-year timespan, ending in 2019. Age, sex, race, severity of injury, severity of shock, type of iliac repair (open or endovascular), mechanism, morbidity and mortality were recorded. Patients with IAI were stratified by both type of repair and mechanism and compared. Multivariable logistic regression analysis was used to identify independent predictors of mortality.ResultsOperative IAI was identified in 507 patients. Of these injuries, 309 (61%) were penetrating and 346 (68.2%) involved the external iliac artery. The majority of patients were male (82%) with a median age and ISS of 31 and 20, respectively. Endovascular repair was performed in 31% of cases. For patients with penetrating injuries, the type of repair impacted neither morbidity nor mortality. For blunt-injured patients, endovascular repair was associated with lower morbidity (29.3% vs 41.3%; p = 0.082) and significantly reduced mortality (14.6% vs 26.7%; p = 0.037) compared with the open-repair approach. Multivariable logistic regression identified endovascular repair as the only modifiable risk factor associated with decreased mortality (odds ratio 0.34; 95% CI 0.15 to 0.79; p = 0.0116).ConclusionsTraumatic IAI causes significant morbidity and mortality. Endovascular repair was identified as the only modifiable predictor of decreased mortality in blunt-injured patients with traumatic IAI. Therefore, for select patients with blunt IAIs, an endovascular repair should be the preferred approach.Copyright © 2023 by the American College of Surgeons. Published by Wolters Kluwer Health, Inc.
