Anterior Corpus Callosotomy Using Laser Interstitial Thermal Therapy for Refractory Epilepsy

Corpus callosotomy is a viable treatment for patients with refractory generalized or multifocal epilepsy, particularly those who have drop attacks. Laser interstitial thermal therapy (LITT) is a minimally invasive surgical option for various intracranial lesions. In this report, we present a 2-trajectory thermal ablation using the NeuroBlate® system (Monteris Medical, MN, USA) for an anterior two-thirds callosotomy in a patient with refractory epilepsy and frequent drop attacks. Adequate ablation of the corpus callosum was confirmed by MRI during the procedure. At the 1-month follow-up, the frequency had decreased from multiple seizures per day to only 3 over the course of 1 month. In addition, he had not suffered any drop attacks or tonic-clonic movements since the procedure. Five months after surgery, seizures had decreased to 1 per month with no drop attacks or loss of consciousness, consistent with an Engel class II outcome. In conclusion, LITT ablation of the corpus callosum is a safe, feasible, and minimally invasive treatment option for patients with refractory epilepsy, and it may be an attractive alternative for patients unwilling or unable to undergo open surgery.
