Summary
Electrocorticography (ECoG) may aid in surgical planning for intractable epilepsy. This study suggests ECoG can guide lesionectomies, even when resection occurs independently of ECoG findings, showing potential utility.
Area of Science:
- Neurosurgery
- Epileptology
- Neurophysiology
Context:
- The role of electrocorticography (ECoG) in planning lesionectomies for epilepsy is debated.
- Intractable epilepsy presents significant management challenges.
Purpose:
- To evaluate the utility of ECoG in guiding surgical interventions for patients with epileptic crises.
- To assess the correlation between ECoG findings and lesion resection outcomes.
Summary:
- This study involved 5 patients with epileptic crises, including arteriovenous malformations and low-grade gliomas.
- Electrically active potentials were observed at lesion margins and sometimes over lesions.
- Lesion resection was performed based on anatomical considerations, with ECoG findings noted but not solely dictating the resection margins.
Impact:
- Preliminary findings suggest ECoG can be a valuable tool in surgical planning for intractable epilepsy.
- This technique may improve surgical outcomes by providing neurophysiological guidance during lesionectomies.
