Abstract:
Prior studies evaluating observation versus angioembolization (AE) for blunt liver injuries (BLT) with contrast extravasation (CE) on computed tomography imaging have yielded inconsistent conclusions, primarily due to limitations in single-center and/or retrospective study design. Therefore, this multicenter study aims to compare an observation versus AE-first approach for BLT, hypothesizing decreased liver-related complications (LRCs) with observation. METHODS We conducted a post hoc analysis of a multicenter, prospective observational study (2019–2021) across 23 centers. Adult patients with BLT + CE undergoing observation or AE within 8 hours of arrival were included. The primary outcome was LRCs, defined as perihepatic fluid collection, bile leak/biloma, pseudoaneurysm, hepatic necrosis, and/or hepatic abscess. A multivariable logistic regression analysis was used to evaluate risk factors associated with LRCs. RESULTS From 128 patients presenting with BLT + CE on imaging, 71 (55.5%) underwent observation-first and 57 (45.5%) AE-first management. Both groups were comparable in age, vitals, mechanism of injury, and shock index (all p 〉 0.05), however the AE group had increased frequency of American Association for the Surgery of Trauma Grade IV injuries (51.0% vs. 22.0%, p = 0.002). The AE cohort demonstrated increased rates of in-hospital LRCs (36.8% vs. 12.7%, p = 0.038), emergency department representation (25.0% vs. 10.0%, p = 0.025), and hospital readmission for LRCs (12.3% vs. 1.4%, p = 0.012). However, the two cohorts had similar mortality rates (5.7% vs. 5.3%, p = 0.912). After adjusting for age, ISS, and grade of liver injury, an AE-first approach had a similar associated risk of LRCs compared with observation-first management (odds ratio, 1.949; 95% confidence interval, 0.673–5.643; p = 0.219). CONCLUSION Patients with blunt liver injury and CE undergoing an observation-first approach were associated with a similar adjusted risk of LRCs and rate of mortality compared with AE-first approach. Overall, this calls for reevaluation of the role of routine AE in blunt liver trauma patients with CE. Future prospective randomized trials are needed to confirm these findings.
