To evaluate the effect of autologous whole blood (AWB) collection on intraoperative/postoperative allogeneic blood transfusion rate in complex aortic surgery with hypothermic circulatory arrest.


 This retrospective study included adults who underwent aortic surgery with hypothermic circulatory arrest at a single institution between 2014 and 2019.  Pre-pump autologous blood collection may reduce the need for intraoperative transfusion of allogenic non-red-cell blood products in patients undergoing complex aortic surgery with hypothermic circulatory arrest.
