Abstract:
Objective To improve the operative outcome of parasagittal meningiomas in central area. Methods Twenty patients with parasagittal meningiomas were treated with microsurgery. Of them, 16 cases were taken DSA exzamination before operation to evaluate the blood supplies of the tumor, compensation of venus return around the tumor after obstruction of the sagittal sinus. During the operation, the parasagittal blood supplies were blocked first, the tumors were resected piece by piece. Rolandic veins, other compensative venous pathways and normal brains around the tumors were protected, and the involved sagittal sinuses were appropriately treated. Results Total removal of the tumor was reached in 17 cases, nearly total removal in 3 cases, no death. Postoperatively, 1 patient developed hemiparesis, 2 had paresis of both lower extremities. No tumor recurrence was found in 13 patients during the follow-up of 3～7 years. Conclusion Using microsurgical techniques in the resection of parasagittal meningioma in central area may improve the percentage of total tumor resection, decrease the injuries of important functional area of the brain, reduce complications and improve survival outcome.
