Abstract
BACKGROUND: Angioembolization has become an increasingly utilized adjunct for splenic preservation after trauma. Embolization of the splenic artery may produce a transient systemic hypercoagulable state. This study was designed to determine the risk of venous thromboembolism (VTE) in blunt trauma patients managed nonoperatively with splenic angioembolization, relative to those managed without. METHOD: Retrospective review of the American College of Surgeons Trauma Quality Improvement Performance (TQIP) Database from 2013 to 2016. Adult (>16 years) patients with isolated, severe (Grades III-V) blunt splenic injuries managed nonoperatively who received pharmacological VTE prophylaxis formed the study population. Outcomes included deep venous thrombosis (DVT), pulmonary embolism (PE), or any VTE. RESULTS: A total of 2643 patients met inclusion criteria (69.1% Grade III, 26.5% Grade IV, 4.5% Grade V). The incidence of DVT was 4.5% in patients who underwent angioembolization, compared to 1.4% in patients who did not (p<0.001). Multivariable analysis showed that angioembolization was an independent risk factor for both DVT (OR 2.65, p = 0.006) and any VTE (OR 2.04, p = 0.01). Analysis according to splenic injury Grades showed that angioembolization remained an independent risk factor for DVT (p = 0.004) in the Grade IV-V injury group, and for VTE (p<0.01) in the Grade III injury group. Initiation of pharmacological VTE prophylaxis 48 h after admission was associated with increased VTE rates in comparison to early initiation (OR 1.75, p = 0.02) CONCLUSIONS: Splenic artery angioembolization may be an independent risk factor for VTE events in isolated, severe blunt splenic trauma managed nonoperatively. Early prophylaxis with LMWH after intervention should be strongly considered.
