Unfortunately, tumors or abnormal collections/ configurations of blood vessels (vascular malformations) can occur in or around these areas and cause significant symptoms.
Surgery can be performed to improve the symptoms and remove the tumor or vascular malformation.If a tumor or vascular malformation is present in, or compressing, an “eloquent” area, surgery can be performed to improve the symptoms and remove the tumor or vascular malformation.
Usually, brain surgery is performed with a patient asleep. Even though the brain tissue itself does not feel pain and does not hurt, patients often are more comfortable and less anxious having brain surgery performed while asleep.
When an “eloquent” area of the brain requires surgery, it is safer to perform the surgery awake. This allows us to have the patient speak or move their arms and legs during surgery while we work around the important structures to make sure they are not injured. Surprisingly, patients usually tolerate this procedure very well and we can still limit the patient’s anxiety with little discomfort.
