Brain mapping with direct electrical stimulation is usefull when the tumor is located near or has infiltrated the central lobe.To analyze the surgical findings with direct electrical stimulation of the cortex and white matter under general anesthesia during surgery for brain tumors related to the central lobe.We studied 42 patients operated on from June 2000 to June 2003. We analyzed surgical findings and details of brain mapping.The mean value of the intensity of the stimulus was greater among those who presented motor deficit prior to surgery (p = 0.0425) and edema on MRI (p = 0.0468) or during anesthesia with continuous propofol (p = 0.001).The functional mapping of the central lobe may be influenced by severe motor deficit, edema on MRI and propofol's anesthesia. |
