Nielsen AW, et al. - Researchers sought to assess the association between perioperative bleeding and postoperative venous thromboembolism (VTE) in bariatric surgery. They observed a significantly increased risk for VTE among bariatric surgery patients who receive postoperative blood transfusion. The etiology of VTE in those who are transfused seemed multifactorial and was possibly related to withholding chemoprophylaxis and the potential of a hypercoagulable state induced by the transfusion. In those who bleed, they recommended considering reinitiating chemoprophylaxis when safe, extending treatment after discharge, and screening ultrasound.
