概括

立体电脑学导向的射频热凝血 (SEEG导向的RF-TC) 提供了对抗药性的治疗方法. 使用SEEG指导的SOZA切除发作区域显示出比部分切除更好的结果,这表明网络参与是关键.

科学领域:

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

背景情况:

焦点抗药性是一种重大的临床挑战.
立体电脑学导向的射频热凝 (SEEG导向的RF-TC) 是一种成熟的治疗选择.
了解在发性网络中的除位置对结果的影响至关重要.

研究的目的:

调查SEEG引导的RF-TC切除在发性网络中的确切位置与临床结局之间的关系.
为了比较切除整个发作发作区与部分发作发作区的疗效.

主要方法:

在接受SEEG指导RF-TC的18名患者中,追溯分析了发作结果.
基于废除目标的子组分析:SEEG引导的发作区域废除 (SOZA) 与SEEG引导的部分发作区域废除 (P-SOZA).
评估结果,包括发作自由度和6个月后的响应率.

主要成果:

整体队列的发作自由率在22%-50%之间,响应率在67%-85%之间.
与SEEG指导的P-SOZA相比,SEEG指导的SOZA在6个月后显示出更高的发作自由度 (p=0.294) 和响应率 (p=0.014).
与SOZA一起消除早期发病的传播并没有改善发病的自由度,但维持了响应率,这表明网络中断.

结论:

切除在发性网络中的位置显著影响SEEG指导的RF-TC结果.
针对整个发作发作区 (SOZA) 似乎比部分切除 (P-SOZA) 更有效.
消除早期发作的扩散可能会通过破坏网络功能来促进发作控制.

关键词:

Electroconvulsive Therapy

Electroconvulsive Therapy

Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early...
