Abstract

A patient with hemophilia and factor VIII inhibitors required urgent evacuation of a spinal cord hematoma. Two large doses of recombinant factorVIIa (200 µg/kg followed by 300 µg/kg) were required for hemostasis. Traditional and rotational thrombelastography were used to guide dose and timing of rFVIIa therapy. With the limitations of prothrombin and partial thromboplastin times as perioperative monitors of rFVIIa efficacy, this description of thrombelastography supports reports of in vitro use, and may be helpful when large perioperative doses of rFVIIa are required.
