Microsurgical ressection for parasagittal meningiomas with preservation of the parasagittal sinus and excelent neurovascular control

Objective:It was to observe whether a microsurgical gross total removal (GTR) of a parasagittal meningioma (PSM) outside the sinus is a safe and efficient procedure.Method:We identify 58 parasagittal meningiomas patients. Medical charts, operative reports, imaging studies and clinical follow-up evaluations were reviewed.Results:GTR of the mass was achieved in 45 (77.7%) instances. The surgical mortality rate was 1.7%. The median follow-up time was 63 months.Conclusion:The surgical approach used in this group of patients afford that the great majority of tumors could be totally removed with low mortality, proving to be safe and effective.
