Translational view: Ablative methods in in vivo epilepsy models

Area of Science:

• Neurology
• Neurosurgery
• Biomedical Engineering

Background:

• Novel epilepsy treatments, including neurostimulation and drugs, are initially evaluated in animal models.
• Radiofrequency thermoablation and laser interstitial thermal therapy represent emerging approaches for epilepsy management.

Purpose of the Study:

• To review and synthesize findings from in vivo experimental studies on radiofrequency thermoablation and laser interstitial thermal therapy for epilepsy.
• To assess the current state of research regarding the feasibility, efficacy, and safety of these thermal ablation techniques in preclinical models.

Main Methods:

• Systematic literature search for in vivo studies on radiofrequency ablation and laser interstitial thermal therapy in epilepsy models.
• Analysis of studies focusing on the application of these techniques for seizure focus ablation and technical parameters.

Main Results:

• Only two in vivo studies directly investigated radiofrequency ablation for acute seizure focus treatment, utilizing transcranial and transvenous approaches.
• The majority of reviewed studies concentrated on technical aspects of functional brain ablation, including temperature, duration, and device parameters.
• Limited research exists on the direct in vivo application of laser interstitial thermal therapy for epilepsy.

Conclusions:

• The fundamental concept of functional ablation for epilepsy is established through open resective surgery.
• Further in vivo research is needed to fully elucidate the efficacy and safety of radiofrequency thermoablation and laser interstitial thermal therapy for epilepsy.
• Preclinical studies should move beyond basic proof of concept to address specific technical challenges and clinical translation.
