Hemodynamic improvement of anterior cerebral artery territory perfusion induced by bifrontal encephalo(periosteal)synangiosis in pediatric patients with moyamoya disease: a study with brain perfusion SPECT

Objective The reinforcement of the anterior cerebral artery (ACA) territory perfusion is important for the future intellectual functioning of pediatric moyamoya disease (MMD) patients. To evaluate the hemodynamic improvement of the ACA territory, bifrontal encephalogaleo-(periosteal)synangiosis [EG(P)S] combined with encephaloduroarteriosynangiosis (EDAS) was compared with EDAS alone in pediatric MMD patients using brain perfusion SPECT.
