Area of Science:

  • Neurosurgery
  • Epileptology
  • Medical Devices

Background:

  • Epilepsy surgery requires precise identification of epileptogenic zones.
  • Existing methods may have limitations in cost, portability, or real-time application.

Purpose of the Study:

  • To evaluate a novel digital, real-time, portable electrocorticography (ECoG) system for epilepsy surgery.
  • To assess the utility and safety of this new ECoG method.

Main Methods:

  • A cohort of 16 patients undergoing epilepsy surgery were evaluated using the new digital, real-time, portable ECoG system.
  • The system was utilized over a 28-month period.

Main Results:

  • No complications were reported during the procedures.

  • The ECoG examination was found to be useful in 13 out of 16 patients (81.25%).
  • The method demonstrated reliability and simplicity.

    • Conclusions:

    • The digital, real-time, portable ECoG method is a safe and effective tool for defining epileptogenic regions during epilepsy surgery.
    • Its low cost and ease of use suggest broad applicability, including in surgeries for tumors, vascular malformations, and other cortical lesions causing seizures.
