颅底脑膜瘤是一种技术上具有挑战性的肿瘤，因为其深部血管供应可能会妨碍切除过程中的早期断流术。术前栓塞这些供血动脉被认为可以减少失血并促进切除;然而，鉴于这些颅底病变的复杂和多样的解剖结构，术前栓塞并非没有风险。血管内和颅底神经外科医生必须根据潜在受益了解这些风险。作者回顾了颅底脑膜瘤的血管解剖、术前血管离断术的适应证、血管内技术和已发表的关于这些病变栓塞的结果。
Skull base meningiomas are technically challenging tumors to treat because of their deep vascular supply that can preclude early devascularization during resection. Preoperative embolization of these arterial feeders is thought to decrease blood loss and facilitate resection; however, given the complex and varied anatomy of these skull base lesions, preoperative embolization is not without risk. It is essential for both endovascular and skull base neurosurgeons to understand these risks in light of the potential benefits. The authors review the vascular anatomy of skull base meningiomas, indications for preoperative devascularization, endovascular techniques, and published results regarding embolization of these lesions.
