Background
The insular cortex is not routinely removed in modified functional hemispherectomy due to the risk of injury to the main arteries and to deep structures. Our study evaluates the safety and usefulness of applying intraoperative electrocorticography (ECoG) on the insular during the hemispherectomy.
Methods
We included all patients who underwent insular ECoG during a modified functional hemispherectomy from 2012 to 2015. After the surgery, the decision for further resection of the insular cortex was made based on the presence of electrographic seizures on ECoG.
Results
The study included 19 patients (age, 6.4 ± 4.7 years, mean ± standard deviation). Electrographic seizures were identified in 5 patients (26.3%). Sixteen of the 19 patients (84.2%) became seizure-free with a follow-up duration of 3.1 ± 0.6 years and no vascular complication occurred.
Conclusions
Intraoperative insular ECoG monitoring can be performed safely while providing a tailored approach for insular resection during modified hemispherectomy.
