Abstract:

Meningiomas occluding the superior sagittal sinus (SSS) present a significant surgical challenge. Given the intricate relationship between tumor tissue and venous structures, there is no consensus on the optimal surgical approach. Depending on the origin of the tumor, meningiomas associated with the SSS can be classified into two types: type Ⅰ (parasagittal meningiomas) and type Ⅱ(sagittal sinus meningiomas). Both types exhibit distinct imaging characteristics and require different surgical strategies. Preoperative evaluation of the venous collateral circulation surrounding the tumor is essential to assess venous compensatory capacity and guide intraoperative decision-making. This video focuses on maximizing tumor resection while preserving venous integrity.

Key words: Meningioma, Superior sagittal sinus, Venous collateral circulation, Surgical strategy
