Brief summary
The purpose of this study is to determine whether autologous platelet rich plasma (APRP)is effective in reducing allogeneic blood transfusions during aortic surgery using deep hypothermic circulatory arrest.
Interventions
15 to 20 mL/kg of whole blood is collected before the administration of heparin from a large-bore central venous access,and is separated into red blood cells component and autologous platelet-rich plasma component by an autologous transfusion system(Sorin Group Electa Essential; Sorin Group Italia, Milan, Italy).
