Abstract: Objective To investigate the efficacy and safety of microneurosurgery associated with gamma knife on venous sinuses meningiomas.
MethodsFrom June 2008 to July 2013， 34 patients with venous sinus meningiomas were underwent microneurosurgery. All the patients accepted MRI examination in 1-3 months after operation. Cases of Simpson Ⅱand Ⅲ grade resection received gamma knife therapy to decrease recurrence.Results Among the 34 patients， Simpson I， Ⅱand Ⅲ grade resection was achieved in 9， 20 and 5. Nine cases suffered muscle weakness， and no brain swelling, serious disablity and death occurred. Twenty-five cases of Simpson Ⅱand Ⅲ grade received gamma knife treatment in 1-3 month after operation with total dose of 8.20Gy. The follow-up ranged 3-36 months.
