Reinfusion of blood within aneurysm sac: a simple method of intraoperative blood conservation in elective abdominal aortic surgery.

Autologous blood conservation reduces postoperative morbidity and mortality. In elective abdominal aortic aneurysm repair, the blood within the aneurysm sac is generally neglected during surgery. We present a simple method of additional blood conservation in elective abdominal aortic surgery, which involves reinfusion of autologous blood within the aneurysm sac in the perioperative period.
