[Preoperative blood storage and intraoperative blood recovery in elective treatment of abdominal aorta aneurysm].
We evaluated the efficiency and costs-effectiveness of blood predonation and intraoperative salvage in elective abdominal aortic aneurysm surgery. Between January 1992 and January 1994, 66 patients (59 male and 7 female, aged 69.9 +/- 0.8 years) who underwent elective surgical repair of an AAA were selected for the study. Thirty-six (54.5%) patients (Group 1) intra- and/or postoperatively received homologous blood whereas 30 (45.5%) patients (Group 2) received autologous blood predonation and intraoperative blood aspiration and reinfusion. The two groups were similar for demographic data, aneurysmal diameter and associated diseases and/or risk factors (p = NS). Operative mortality was comparable between the two groups (p = NS). The mean intraoperative blood loss was 803.4 +/- 104.5 ml in group 1 and 812.8 +/- 44.8 ml in group 2 (p = NS). Group 2 patients received intra- or postoperatively a mean of 0.8 +/- 0.2 units of homologous blood (p < 0.001). Aneurysmal diameter did not influence the transfusion requirement between the two groups (p = NS). The cost per unit of homologous banked blood was significantly higher (p < 0.01). Cumulative costs of the procedures did not show statistical differences between the two groups (p = NS). Aortic surgery is the ideal target for predonation and intraoperative blood salvage.
