Abstract:Objective:To summarize the strategies for venous protection and key techniques of falx reconstruction during the re-section of parasagittal and falcine meningiomas,thereby improving surgical safety and prognosis.Methods:The Clinical data of 56 pa-tients with parasagittal and falcine meningiomas were retrospectively reviewed.Patients'recovery was assessed via outpatient follow-up.Key technical points for venous protection and falx reconstruction were summarized and discussed alongside literature.Results:All 56 patients recovered well postoperatively,with no mortality.Among them,52 patients showed no hemorrhage or severe cerebral edema on CT scans at approximately 3 hours postoperatively,while 4 had minor hemorrhage.8 patients developed contralateral limb hemiplegia a-round postoperative day 3,and 13 experienced secondary epilepsy,all of which improved with treatment.The preoperative mean KPS score was 81.5±6.7.After 2~3 years of follow-up,the mean KPS score increased to 90.3±5.2.No tumor recurrence,severe paralys-is,or intractable epilepsy was observed.Conclusion:Parasagittal and falcine meningiomas involving the sagittal sinus and deep draining veins require preoperative imaging to clarify tumor-vascular relationships and formulate surgical plans.Intraoperatively,adequate expo-sure of the tumor and surrounding vessels,meticulous protection of draining veins,and reconstruction of the resected falx are critical.These strategies ensure favorable overall outcome.
