Introduction Although reports on angioembolization (AE) show favorable results for severe hepatic trauma, information is lacking on its benefit in the management and mechanisms of injury (MOI). This study examined patient outcomes with severe hepatic injuries to determine the association of in-hospital mortality with AE. The hypothesis is that AE is associated with increased survival in severe hepatic injuries. Methods Demographics, age, sex, MOI, shock index (SI), ≥6 units packed red blood cells (PRBCs) per hospital length of stay (LOS), intensive care unit LOS, injury severity score (ISS), and AE were collected. The primary outcome was in-hospital mortality. Patients were stratified into groups according to MOI, AE, and operative vs non-operative management. Multivariable logistic regression determined the independent association of mortality with AE vs no AE and operative vs nonoperative management and modeled the odds of mortality controlling for MOI, AE vs no AE, age and ISS groups, SI >.9, and ≥6 units PRBCs/LOS. Results From 2013 to 2018, 2462 patients (1744 blunt; 718 penetrating) were treated for severe hepatic injuries. AE was used in only 21% of patients. Mortality rates increased with higher ISS and age. AE was associated with mortality when compared to patients who did not undergo AE. The strongest associations with mortality were ISS ≥25, transfusion ≥ 6 units PRBCs/LOS, and age ≥65 years. Conclusions AE is underutilized in severe hepatic trauma. AE may be a valuable adjunct in the treatment of severe hepatic injuries especially in older patients and those needing exploratory laparotomy.
