Stereoelectroencephalography to localize epileptic foci in children

Abstract

Stereoelectroencephalography (SEEG) is a technique for invasive localization of the epileptogenic zone that involves percutaneous placement of stereotactically targeted depth electrodes for simultaneous recording from neocortical and subcortical brain structures. Although SEEG has been utilized in Europe and Canada for many years, it is beginning to gain traction throughout the Americas as it allows simultaneous recording from both superficial and deep brain structures through a percutaneous approach. The purpose of this manuscript is to review the use of SEEG as it relates specifically to localization of the epileptogenic zone in pediatric epilepsy surgery. We review the literature to describe the history, indications, surgical technique, outcomes, and complications of SEEG.
