Acute normovolemic hemodilution (ANH) is a blood conservation technique that involves withdrawing blood from a patient before surgery and replacing it with a combination of crystalloid and/or colloid solutions, prior to any surgical bleeding. The withdrawn blood can be re-infused during or after the surgical procedure to reduce the need for allogeneic blood transfusions. Patients with high levels of hemoglobin (Hb) and hematocrit (Hct) are at an increased risk of thromboembolic events due to the higher whole blood viscosity (WBV). By reducing blood cell concentration and blood viscosity, ANH can decrease the thromboembolic events during and after surgery in patients with elevated Hb and Hct levels. This article specifically describes the application of ANH in a patient with critical limb ischemia who underwent lower limb thrombectomy and presented with high Hb and Hct levels. ANH presents a promising new approach to reducing the need for allogeneic blood transfusion, while also potentially decreasing the rate of thromboembolic events perioperatively. However, further research is needed to determine the optimal target Hct for patients with polycythemia undergoing ANH, which will help to establish a goal directed ANH. Additionally, the safety and efficacy of ANH should be evaluated in larger populations to ensure its effectiveness and safety. Despite these limitations, ANH remains a compelling and exciting new approach to minimizing the risk of thromboembolic events during and after surgery, and may represent an important tool for improving patient outcomes in the future.
