OBJECTIVE: To evaluate the optimal timing of thromboprophylaxis (TPX) initiation after hepatic angioembolization in trauma patients.
BACKGROUND: TPX after hepatic trauma is complicated by the risk of bleeding, but the relative risk after hepatic angioembolization is unknown.
METHODS: Patients who underwent hepatic angioembolization within 24 hours were retrospectively identified from the 2017 to 2019 American College of Surgeons Trauma Quality Improvement Project data sets. Cases with <24-hour length of stay and other serious injuries were excluded. Venous thromboembolism (VTE) included deep venous thrombosis and PE. Bleeding complications included hepatic surgery, additional angioembolization, or blood transfusion after TPX initiation. Differences were tested with univariate and multivariate analyses.
RESULTS: Of 1550 patients, 1370 had initial angioembolization. Bleeding complications were higher in those with TPX initiation within 24 hours (20.0% vs 8.9%, P <0.001) and 48 hours (13.2% vs 8.4%, P =0.013). However, VTE was higher in those with TPX initiation after 48 hours (6.3% vs 3.3%, P =0.025). In the 180 patients with hepatic surgery before angioembolization, bleeding complications were higher in those with TPX initiation within 24 hours (72% vs 20%, P <0.001), 48 hours (50% vs 17%, P <0.001), and 72 hours (37% vs 14%, P =0.001). Moreover, deep venous thrombosis was higher in those with TPX initiation after 96 hours (14.3% vs 3.1%, P =0.023).
CONCLUSIONS: This is the first study to address the timing of TPX after hepatic angioembolization in a national sample of trauma patients. For these patients, initiation of TPX at 48 to 72 hours achieves the safest balance in minimizing bleeding while reducing the risk of VTE.
LEVEL OF EVIDENCE: Level III-retrospective cohort study.
