Blood Transfusion for Lower Extremity Bypass Is Associated with Increased Wound Infection and Graft Thrombosis

From this observational study, it appears transfusion does not have major consequences during mid-term follow-up, but the presumed benefits of blood replacement should be weighed carefully because of the increased risk of perioperative complications with transfusion.
