摘要: Resume La resection des gliomes de bas grade en condition eveillee est une intervention d’actualite. Elle permet au neurochirurgien la realisation d’un geste le plus large possible tout respectant les regions dites fonctionnelles (par exemple, motricite, langage). Le reperage anatomique ces base principalement sur donnees stimulation corticale. stimulation, induisant « desorganisation transitoire » dite positive si tâche realisee par patient perturbee lors celle-ci. region stimulee alors consideree comme participant a fonction testee. Il existe dans certaines circonstances questions quant fiabilite reponses obtenues. En effet seuil d’excitabilite corticale peut varier, selon topographie Comment connaitre l’intensite optimale appliquer ? entrainer, egalement, desorganisation distance raison l’existence d’importantes connexions cortico-corticales presentes notre systeme. etre certain du caractere focal conditions ? L’enregistrement conjoint l’activite electrique (electrocorticographie-ECoG) repondre questions. ainsi d’augmenter specificite (desorganisation locale/fonction) et sensibilite (stimulation d’intensite trop faible) cette technique. offre ailleurs d’interessantes perspectives.
