Intractable epilepsy in vascular congenital hemiparesis: clinical features and surgical options

Forty-one patients with vascular congenital hemiplegia and intractable epilepsy were reviewed. Most had severe hemiparesis, mental retardation, porencephaly, and focal epilepsy. Thirty-three were considered surgical candidates and 25 underwent surgery. Seizure freedom and significant seizure reduction were achieved in 12 of 13 patients after functional hemispherectomy, 4 of 6 after temporal lobectomy, 2 of 2 with extratemporal focal resections, 1 of 3 with corpus callosotomy, and 1 with porencephalic cyst drainage.
