Microsurgical removal of parasagittal meningiomas

Objective To improve the curative effect of microsurgery on parasagittal meningioma. Methods A retrospective analysis was performed on the clinical data of 67 parasagittal meningiomas. Results Simpson Grade Ⅰ resection was achieved in 24(35.8%), Grade Ⅱ in 37(55.2%) and Grade Ⅲ in 6(9.0%). 2 patients died after operations. In the rest of patients, 1 developed hemiparalysis and 1 paralysis of both lower extremities. 48 patients were followed up for 1 to 5 years, only with 5 recurrences. Conclusion Efficient management of operative bleeding, application of microsurgical techniques, protection of the sagittal sinus, avoidance of damages to cerebral cortex, veins of central sulcus as well as other draining vein are the important factors to improve the rate of surgical resection and overall outcomes in patients with parasagittal meningiomas.
