Functional hemispherectomy in children.

摘要: Functional hemispherectomy, indicated for the control of pharmacologically refractory seizures, has been used at Montreal Neurological Hospital since 1974. We have this technique in 18 children suffering from intractable seizures secondary to conditions such as infantile hemiplegia, chronic encephalitis, head trauma, cerebrovascular accident, brain dysplasia and Sturge-Weber angiomatosis. None developed superficial cerebral hemosiderosis often seen following classical anatomical hemispherectomy. Eighty-two per cent (82%) patients seizure-free hospital discharge while another 11.5% had least 80% reduction their seizure frequency. Most shown an improvement intellectual capacity sociability.
