Should the Cell Saver Autotransfusion System Be Routinely Used in Elective Aortic Surgery?

The objective of this study is to identify the aortic surgery procedures in which the use of the Cell Saver autotransfusion system is beneficial in terms of the amount of autologous blood recovered and the reduction in blood bank demands. An evaluation of the cost-effectiveness of the system is also presented. Four hundred and thirty-four elective aortic interventions were retrospectively reviewed to examine the use of intraoperative autotransfusion (IAT). Evaluation was made of risk factors, preoperative hematological variables, the volume of IAT-processed reinfused blood, and homologous transfusion requirements over the period of hospitalization. The routine use of the IAT system was cost-effective in the interventions for AAA and TAA. In patients subjected to aortobifemoral bypass for aortoiliac occlusive disease, IAT served to alleviate demands on blood bank inventories, although in our center its use led to a slight increase in net cost. The routine use of IAT during unilateral revascularization due to occlusive disease offered no benefits in terms of reduced homologous transfusion requirements or cost-effectiveness.
