    Intraoperative autotransfusion using a cell saver is a safe and effective method to salvage blood during major aortic aneurysm surgery. This technique helps reduce blood loss and is a valuable adjunct in vascular procedures.

    Area of Science:

    • Cardiovascular Surgery
    • Anesthesiology
    • Transfusion Medicine

    Context:

    • Major vascular surgery for large aortic aneurysms involves significant blood loss.
    • Intraoperative autotransfusion aims to mitigate this by salvaging and reinfusing the patient's own blood.
    • Cell saver technology is employed for blood salvage during these procedures.

    Purpose:

    • To evaluate the efficacy and safety of intraoperative autotransfusion using a cell saver in patients undergoing aortic aneurysm repair.
    • To quantify the volume of red blood cells retransfused and assess the quality of salvaged blood.
    • To determine the clinical utility of this technique in thoraco-abdominal and abdominal aortic aneurysm surgeries.

    Summary:

    • Sixty-five patients undergoing aortic aneurysm repair (16 TAA, 49 AAA) had their blood salvaged intraoperatively using a cell saver.

  • Mean retransfused red blood cell volumes were 1.21 L for AAA and 3.61 L for TAA.
  • Analysis of salvaged blood showed low levels of heparin and protein, with minimal hemolysis (89.5 µmol/L), and a T1/2 of 21 days for chrom51.

    • Impact:

    • Intraoperative autotransfusion is confirmed as a valuable and safe adjunct in major vascular surgery.
    • This technique can significantly reduce the need for allogeneic blood transfusions.
    • The study supports the routine use of cell saver technology in complex aortic surgeries.
