To assess the effect of a rotational thromboelastometry (ROTEM)-enhanced transfusion algorithm with hemostatic agents on allogenic blood transfusion in patients undergoing frozen elephant trunk (FET) surgery. ⋯ A ROTEM-enhanced transfusion strategy halved intraoperative transfusion in the setting of FET. Further studies are needed to confirm the magnitude of our findings on clinically relevant endpoints.
