title: Hemodynamics before and after the total removal of a dural arteriovenous malformation of the posterior fossa. Case report.
abstract: The hemodynamic change before and after the successful total removal of a dural arteriovenous malformation was reported. Preoperative dynamic computed tomography scan showed the prolongation of the cerebral circulation time, and postoperative dynamic computed tomography scan demonstrated improvement of the cerebral hemodynamics, despite total resection of transverse sinus and sigmoid sinus. These findings suggest that, when angiography shows either retrograde venous filling or sinus occlusion, total removal could be done safely.
