Preoperative and Postoperative Evaluation of Cerebral Perfusion and Vasodilatory Capacity With ^99m Tc-HMPAO SPECT and Acetazolamide in Childhood Moyamoya Disease

Abstract

Hemodynamic compromise existed in patients with childhood moyamoya disease and was a major cause of development of ischemic symptoms. Regions in which hemodynamic compromise was present could be determined by measuring regional cerebral perfusion and vasodilatory capacity.
