ABSTRACT
Catastrophic epileptic encephalopathies in children comprise devastating conditions that features cerebral dysfunction in association with refractory epileptic seizures. The diagnosis is based on the clinical findings, on magnetic resonance imaging (MRI) of the brain and on electroencephalographic findings. For these conditions, surgery remains essential for attaining seizure control. We report two cases of 5-year-old girls. The first one had a diagnosis of Rasmussen’s syndrome. The second one had a large porencephalic cyst secondary to perinatal cerebral ischemia. Despite trials of anticonvulsants, both patients deteriorated, and a functional hemispherectomy guided by neuronavigation was indicated and performed, with low morbidity and excellent seizure control. The neuronavigation proved to be a valuable guidance tool in performing the functional hemispherectomy, making the disconnections more accurate, and thus decreasing the surgical time and blood loss.
RESUMO
Aplicabilidade da neuronavegação em hemisferectomia funcional As encefalopatias epilépticas catastróficas da infância compreendem condições graves que associam disfunção cerebral e crises epilépticas refratárias. Seu diagnóstico é firmado com base nos dados clínicos e nos achados de ressonância magnética e eletrencefalográficos. Para algumas destas condições o tratamento cirúrgico continua sendo essencial para o controle das crises. Relatamos dois casos de pacientes de 5 anos. A primeira teve diagnóstico de síndrome de Rasmussen. A segunda tinha antecedentes de encefalopatia hipóxico-isquêmica perinatal. Ambas apresentaram epilepsia parcial refratária em associação com rápida deterioração neurológica, e foram submetidas à hemisferectomia funcional com auxílio da neuronavegação, com baixa morbidade e excelente controle das crises. A neuronavegação se mostrou como uma valiosa ferramenta na realização da hemisferectomia funcional, possibilitando desconexões mais precisas, menor tempo de cirurgia e menor perda sanguínea.
