科学领域:

神经外科神经外科
发病学 (Epileptology) 是一个专业的学科.
神经生理学神经生理学

背景情况:

标准手术使用低密度 (LD) 电极网,皮质覆盖范围有限.
高密度 (HD) 网格在研究中表现有希望,但需要对手术进行临床评估.

研究的目的:

评估HD网格在手术内外皮电图 (ioECoG) 中的临床实用性.
为了确定HD-ioECoG是否通过检测局部活动和改善尖端发作的局部化来改变手术计划.

主要方法:

分析了接受手术的HD-ioECoG (64个电极,5mm间距) 的患者.
间点尖峰和高频振荡 (HFO),包括波纹和快波纹 (FR),在视觉上是显著的.
使用格兰杰因果关系来评估尖端发病局部.

主要成果:

在20名患者中,HD-ioECoG在6名患者中可能改变了手术计划.
在切除区域检测到更多的FR,与发作自由度相关 (p < .001).
有很大比例的焦点事件 (尖峰,波纹,FR) 发生在一个或两个通道上,可能会被LD网错过.

结论:

HD-ioECoG在临床上可用于指导手术.
HD-ioECoG提供了增强的细节来识别焦点事件,特别是FRs.
通过HD-ioECoG更好地检测焦点事件和尖端发作,可以完善手术决策.
