目的 探讨显微切除延髓实体性血管母细胞瘤术中电生理监测的意义。 方法 2007年7月-2009年8月，在电生理监测下显微切除13例延髓实体性血管母细胞瘤，观察切除程度、死亡率及术后脑干功能，并对电生理监测下的手术技巧进行讨论总结。 结果 完全切除13例延髓实体性血管母细胞瘤，术后因呼吸功能衰竭死亡1例，6个月脑干机能状态较术前保持或改进10例。 结论 延髓实体性血管母细胞瘤切除术中行神经电生理监测有助于提高手术效果，改善预后。
Visual evoked potential (VEP) is a commonly used technique in neurology and ophthalmology in the process of disease diagnosis and treatment, which refers to the electrical signal transmitted by the visual pathway and recorded in the skull or cortex after stimulating the retina. The effect of monitoring and protection of vision in surgery near the visual pathway has attracted more and more attention recently. This article summarizes the experience and problems of intraoperative monitoring of VEP in terms of anesthesiology and instrument development, monitoring technology, and application innovation, and proposes future research directions. The purpose is to provide a reference for clinical application and research of intraoperative VEP monitoring.
