Meningiomas Invading the Superior Sagittal Sinus: Surgical Experience in 108 Cases

Abstract

On the basis of our results, we conclude that if the sinus is partially invaded, it can be opened to obtain as complete a resection as possible and to attempt to preserve the patency of the sinus. If the sinus is obstructed, the portion of the sinus involved can be resected completely. In both situations, extreme care is vital to preservation of cortical veins, which may offer important collateral drainage. With our approach, good results are achieved and it is not necessary to reconstruct the sinus.
