Abstract

Transfusion with old red blood cells (RBCs) was associated with adverse clinical outcomes. The effect of perioperative transfusion of old RBCs on postoperative complications after free muscle sparing transverse rectus abdominis myocutaneous (TRAM) flap surgery was retrospectively investigated. Two hundred sixty-one patients undergoing breast reconstruction were assigned to two groups: no transfusion and transfusion groups. Transfused patients were further divided according to the RBC storage duration (fresh, ≤14 days; old, >14 days). Postoperative complications such as vascular thrombosis, hematoma, and flap congestion were noted. Patients who received old blood (n = 34), compared with those received fresh blood (n = 40) or no transfusion (n = 187), had a higher incidence of postoperative complications (44.1% vs. 20.0% or 12.8%, P < 0.05). Perioperative transfusion of old RBCs can be associated with an increase in postoperative complications after free muscle sparing TRAM flap surgery.
