Now Available On-Demand Ask the Experts Webinar On-Demand | How Do We Know We Have Missed the SEEG Seizure Onset Zone?
Speaker: Philippe Kahane, MD, PhD
Moderator: Jaysingh Singh, MD During the last decade, SEEG has become the most popular technique for invasive evaluation of drug-resistant epileptic patients. Though it appears safer and seems to offers greater chance of seizure freedom than subdural evaluation, SEEG does not guarantee surgery nor seizure freedom. The fact is that SEEG needs strong hypotheses before electrode implantation, with a limited number of intracerebral electrodes that sample only a small part of the brain. One of the difficulties facing the clinicians is to understand, once the electrodes are in place, whether the seizure pattern recorded at seizure onset is relevant or not, which strongly influences the surgical decision. We will review here the main situations suggesting that we missed the seizure onset zone, and consequently that caution is required before deciding to go or not with surgery.
