REBOA in trauma and the risk of venous thromboembolic complications: A matched-cohort study

Abstract

BackgroundResuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) has been used as a damage control procedure in trauma patients. We hypothesized that REBOA increases risk of venous thromboembolic (VTE) complications. MethodsThis was an American College of Surgeons Trauma Quality Improvement Program (ACS-TQIP) database study. Excluded were transfers, deaths within 24 h, and severe head injuries. Included were trauma patients receiving REBOA within 4 h from arrival. Outcomes in the two groups were compared after using propensity score matching (PSM) for demographic and clinical characteristics, body area abbreviated injury scale, injury severity score, pelvis and lower extremity fractures, angiographic intervention, preperitoneal pelvic packing, pharmacological VTE prophylaxis, laparotomy, laparotomy and specific orthopedic procedures. ResultsAfter PSM, 339 REBOA patients were matched with 663 patients with No REBOA. REBOA patients were significantly more likely to develop pulmonary embolism (PE) (5.3% vs. 2.7%, p = .037) and VTE (14.7% vs. 10.0%, p = .025). ConclusionREBOA is associated with an increased risk of PE and VTE complications. Patients managed with REBOA should receive adequate thromboprophylaxis and be monitored closely for VTE complications.
