Clinical Trial of SEEG for Drug-resistant Epilepsy (SEEG-DRE)
A Clinical Trial Evaluating the Safety and Efficacy of Stereoelectroencephalography (SEEG) Electrode Combined With Radiofrequency Lesion System for the Treatment of Drug-Resistant Epilepsy
This trial evaluates the safety and efficacy of SEEG recording and functional mapping for patients with drug-resistant epilepsy. It also assesses the safety and therapeutic effectiveness of SEEG-guided radiofrequency ablation for this patient group. The study will collect clinical evidence to support the standardized application of this combined diagnostic and treatment workflow for drug-resistant epilepsy.

Descripción detallada
Stereoelectroencephalography (SEEG) is a minimally invasive presurgical evaluation modality for epilepsy. Intracranial electrodes are implanted using stereotactic techniques to record intracranial electroencephalographic (EEG) activity and deliver direct electrical stimulation, with the aim of delineating the epileptogenic zone in patients with focal epilepsy. Based on SEEG findings, clinicians can achieve highly precise localization of the epileptogenic zone and tailored surgical planning, or directly utilize SEEG-guided radiofrequency thermocoagulation (SEEG RF-TC) as an independent therapeutic intervention.
This study adopts a single-arm target-value design with a planned enrollment of 99 patients. All enrolled participants will undergo SEEG electrode implantation, followed by continuous SEEG monitoring for EEG recording and comprehensive presurgical evaluation. Eligible patients will then receive SEEG-guided radiofrequency thermocoagulation treatment. The primary efficacy endpoints include the success rate of intracranial EEG signal recording and the therapeutic response rate of thermocoagulation.
