Meningiomas invading the superior sagittal sinus in 36 cases

Objective To improve the curative effect of microsurgery for meningiomas invading the superior sagittal sinus. Methods A retrospective analysis was performed in 36 patients with meningiomas invading the superior sagittal sinus who were treated in our department from January 2004 to June 2009, includingthe clinical presentations, the diagnostic methods and the effect of microsurgery treatment. Results According to Simpson classification of glioma resection, among the 36 patients, Grade Ⅰ resection was performed in 26 cases(72.2 %),Grade Ⅱ in 7 cases(19.4%),11 patients with meningiomas totally occluding the SSS had complete resection of the encased portion of the sinus. No patient died from the surgery, all the patients recovered well after the treatment. Following-up ranged from 0.5 to 4.6 years(mean 2.3year) in 36 patients showed that only one patient suffered a recurrence 3.8 years after the surgery. With total sinus occlusion when received reoperation. Conclusions If the sinus is partially invaded, it can be opened to obtain as complete a resection as possible and to reconstruct the sinus and preserve the patency of the sinus. If the sinus is obstructed, the portion of the sinus involved can be resected completely. Application of microsurgical techniques and restoration are important factors in increasing the success rate of surgical resection, reducing post-operative complications and improving the quality of life.
