Resumen

Los gliomas supratentoriales de bajo grado deben ser sometidos a exéresis completa. Cuando estas lesiones asientan en áreas elocuentes su extirpación puede resultar problemática debido a la posibilidad de inducir secuelas neurológicas. Si el procedimiento se practica bajo anestesia general la resección es frecuentemente subtotal. Intentando aumentar la radicalidad de la exéresis nuestro grupo la ha practicado bajo anestesia local, controlando intraoperatoriamente las funciones neurológicas en peligro.

Diecisiete casos de gliomas de bajo grado fueron extirpados bajo anestesia local y sedación ligera. La exéresis quirúrgica fue completa en 15/17 y subtotal en 2/17. Postoperatoriamente sólo un pacienete presentó una hemiparesia ligera y dos más una disfasia motora transitoria.

Concluimos diciendo que la craniotomía bajo anestesia local permite la extirpación, la mayor parte de las veces completa, de lesiones en áreas elocuentes del cerebro.

Summary

Low grade supratentorial gliomas should be removed radically. When they lay in eloquent areas its removal can be problematic due to the possibility of inducing neurological sequelae. If the procedure is performed under general anaesthesia the resection is often subtotal. Attempting to increase the radicality these cases were performed under local anaesthesia, controlling intraoperatively the endangered neurological functions.

Seventeen cases of low grade gliomas were removed under local anaesthesia and light sedation. Surgical removal was complete in 15/17 cases and subtotal in 2/17. Postoperatively one patient had a slight hemiparesis and two more a transient motor duysphasia.

We conclude saying that craniotomy under local anaesthesia allows the removal, most of the times complete, of lesions in eloquent brain areas.
