Bilateral Superficial Temporal-Middle Cerebral Artery Anastomosis and Encephalo-Myo Synangiosis for Moyamoya Disease

Abstract

Although the etiology of moyamoya disease (MMD) is not known, treatments have been performed. The first was cervical carotid sympathectomy and superior cevical ganglio-nectomy(CCS and SCG)by SUZUKI et al. and the second was superficial temporal-middle cere-bral artery anastomosis (STA-MCA)and encephalo-myo synangiosis (EMS) by KRAYENBÜHL et al. We are presenting two cases of MMD (a 6-years-old girl of twins and 22-years-old women), who developed syndrome of cerebral ischemia, treated by bilateral STA-MCA and EMS, with good results.
