Abstract
Venous thromboembolism (VTE) prophylaxis in the setting of blunt traumatic visceral injury remains controversial. A total of 181 patients underwent splenic artery embolization (SAE) and began pharmacologic VTE prophylaxis at a median time of 59.5 hours (interquartile range, 46 hours). Six patients required splenectomy for rebleed. Fifty-one patients underwent SAE but did not receive anticoagulation therapy since they were considered low risk for VTE, and no splenectomies were performed (P = 1). Multivariate analysis showed no increased risk of need for splenectomy after beginning anticoagulation within 24 hours after SAE (P =.441). This study suggests that patients found to be at a high VTE risk should be considered for thromboprophylaxis within 24 hours after SAE.
