Cerebral metabolic rate for oxygen reduction was observed in \u224880% of pediatric (16\/21; 76%) and adult hemispheres (38\/48; 79%). Surgical revascularization resolved hemodynamic compromise in all operated hemispheres. Cerebral metabolic rate for oxygen significantly improved in pediatric patients without parenchymal lesions (n=8), but not those with parenchymal lesions (n=8).
