Experiencia en gliomas de bajo grado operados con craneotomía vigil y estimulación cortical directa. Serie clínica de 6 pacientes y análisis de la literatura

Abstract

Low grade gliomas (LGG) are a subtype of primary brain tumors characterized by slow grow and infiltrative nature, usually invading the eloquent areas of the brain. This makes the surgical treatment a challenge for the neurosurgeon. The evidence suggests that the early gross total resection is fundamental to change the natural history of the disease and avoid the malignant transformation. In this review we analyze the current literature regarding LGG and we present our experience and protocol. We operate 6 patients with awake craniotomy and direct cortical stimulation to delineate the margins of the resection. The mean preoperative tumor volume was 36,8 ml and the post operative was 6,1. We manage to achieve a significant tumor volume reduction of 83.4%, without post-operative neurological deficits with a safe technique.
