Identification of speech lateralization by intracarotid injection of methohexital

摘要: Speech lateralization was assessed in 25 patients with epilepsy by direct carotid injection of catheterization from a femoral approach. Hemispheric anesthesia induced intracarotid the rapidly acting barbiturate methohexital. This technique allowed same-day study both hemispheres, permitted repeated either artery without accumulation methohexital sufficient to cause systemic effects, and added little total time required for three-vessel cerebral angiography. Unilateral seizures were 4 patients. No other complication secondary observed.
