[Successful treatment of a huge meningeal hemangiopericytoma using Preoperative Autologous Transfusion and Hemodilutional Autologous Transfusion: case report].
We report successful operations for a meningeal hemangiopericytoma using sufficient amounts of Preoperative Autologous Transfusion (PAT) and Hemodilutional Autologous Transfusion (HAT). A 23-year-old woman with amenorrhea and bilateral visual field disturbance was found to have a huge intracranial tumor. MRI showed a well-enhanced cystic mass in the left middle fossa, suprasellar, intrasellar, sphenoidal sinus, and cavernous sinus. Preoperatively, the tumor was thought to be a cystic pituitary tumor or meningioma. Surgical removal was planned in three steps. The first operation was carried out via the transsphenoidal approach. Total blood loss was 1348 ml and 2 MAP infusion were required to control bleeding. Histopathological diagnosis was hemangiopericytoma. After preparation of PAT 400 ml and HAT 800 ml, we carried out the second partial removal operation mainly via the interhemispheric approach. Total blood loss was 1829 ml and required autologous transfusion only. After preparation of PAT 1200 ml and HAT 400 ml, the last total removal operation was carried out mainly via the pterional and subtemporal approach. Total blood loss was 1813 ml and required autologous transfusion only. We needed 2 MAP infusion in the first operation, but were able to perform total removal successfully without homologous blood transfusion because a sufficient amount of PAT and HAT had been prepared preoperatively. Hemangiopericytoma required postoperative radiation therapy to avoid local recurrence. After successful removal of the tumor surgically, postoperative radiation therapy was able to be carried out efficiently.
