Impact of Perioperative Blood Transfusion in Anemic Patients Undergoing Infra Inguinal Bypass.

Objective: Patients who present with lower extremity ischemia are frequently anemic and the optimal transfusion threshold for this cohort remains controversial. We sought to evaluate the impact of blood transfusion on postoperative major adverse cardiac events (MACE), including myocardial infarction, dysrhythmia, stroke, congestive heart failure, and 30-day mortality for these patients.

Methods: All consecutive patients who underwent infra-inguinal bypass at our institution from 2011 to 2020 were included.
