Intraoperative autologous transfusion during major aortic reconstructive procedures.

Area of Science:

• Cardiovascular Surgery
• Transfusion Medicine

Background:

• Major aortic reconstructive procedures carry significant risks, including substantial blood loss and complications from homologous blood transfusions.
• Autologous transfusion offers a potential alternative to mitigate these risks.

Purpose of the Study:

• To evaluate the benefits and drawbacks of autologous intraoperative transfusion during major aortic reconstructive procedures.
• To compare patient outcomes between those undergoing aortic surgery with and without autologous transfusion devices.

Main Methods:

• Retrospective analysis of 50 patients (group 1) without autologous transfusion devices.
• Prospective evaluation of 50 patients (group 2) using autologous transfusion devices for intraoperative blood salvage and reinfusion.
• Assessment of preoperative risk factors and postoperative complications in both cohorts.

Main Results:

• The autotransfusion group (group 2) exhibited lower morbidity and more complete replacement of blood loss.
• Autologous transfusion supplied approximately 75% of transfused blood in group 2, reducing blood bank needs.
• Significant reduction or elimination of risks linked to homologous transfusion, including hemolysis, hepatitis, transfusion-related acute lung injury, anaphylaxis, and transfusion-transmitted AIDS.

Conclusions:

• Autologous intraoperative transfusion is beneficial during major aortic reconstructive procedures.
• This technique reduces postoperative morbidity and the need for banked blood.
• It effectively mitigates the risks inherent in homologous blood transfusions.
