Microsurgical Treatment Of Parasagittal Meningiomas In Central Area

Objective To evaluate the surgery methods and treatment effect of the parasagittalmeningiomas in central area. To introduce the treatment experience of the parasagittalmeningiomas in central area. This article expounded the importance of intraoperativeimportant structure for protection.In order to improve the next to the sagittal sinusmeningioma surgery success rate and reduce postoperative complications and tumorrecurrence.Methods A total of36with parasagittal meningiomas in the central area weretreated with microsurgery. Imaging data of36patients, the surgical approach, methods andstrategies of microsurgical resection of the tumor were analyzed retrospectively. ResultsSimpson I,Ⅱ,and Ⅳgrades resection was achieved in4(11.1％)，15(41.7％)，and17(47.2％)of the36patients respectively.None of the patients died．Two patients developedcerebral edema and infarction and were cured by surgical decompression．3months aftercarried out skull suture line, all return to work life good. Five cases after limb musclestrength improved; Hemiparalysis was deteriorated in10patients，7of them recoveredspontaneously in1to8weeks，and the other3developed hemiparesis．17cases (IVgrades resection) underwent the radiotherapy within one month. Among the patients，25patients were followed up for3months to3years．3patients had recurrent meningiomasin1to3years after the operation, All underwent surgery again. Conclusions Sufficientpreoperative evaluation, choosing appropriate surgical approach, avoid brain cortex injury,central sulcus vein and venous drainage protection and superior sagittal sinus reasonabletreatment all can ensure and improve the curative effect of the operation. We can not beforced the pursuit of full cut when tumor surrounding edema, obvious function and braintissue adhesion closely and tumor and central sulcus vein and around tumor venousdrainage adhesion closely and the tumor invasion superior sagittal sinus.
