Objective: Document the incidence of Spreading Depolarizations inlesional epilepsy surgery.

Methods: This is a prospective study with the goal to study 80 patients. We include adult patients undergoing elective craniotomy for epileptogenic supratentorial lesions lasting >2h. Electrocorticographic recordings were obtained from time of dural opening through the time of dural closure, using a standard 1 × 8 silver electrode coupled with a full-spectrum DC amplifier (0-45Hz, Notch:60Hz). We analyzed the clinical and socio-demographic characteristics. Detection of SDs was set as slow potential changes coupled with suppression of high-frequency ECoG propagating across the electrodes.

Results: From September to November 2017 we already included 16 patients, mean age 37(19-75) years-old, 50% male, underwent 4 callosotomies and 12 temporal lesionectomies (3 cortical dysplasia, 2 cavernomas, 5 gliomas and 2 dermoid cystic). All the patients had history of symptomatic epilepsy, none had postsurgical complications and only 2 patients post-callosotomy continued with seizures at 6 months of follow-up. Until now, we have not documented cases of SDs during these operations.

Conclusion: SDs were absent in this preliminary analysis during lesional epilepsy surgery.
