烟雾病主要是由于颈内动脉(ICA)分叉部或大脑中动脉(MCA)、大脑前动脉近端(ACA)狭窄或闭塞引起,在脑基底部出现异网状血管,常发生在双侧,偶可见于单侧。 作者对76个烟雾病并动脉瘤(Aa)患者进行了研究,包括年龄、性别、民族、发作类型、Aa的数量、大小、位置等因素。根据Aa发生的位置分为主干动脉瘤(MAA)和周围动脉瘤(PAA),根据体积分为小Aa(φ1～9mm)、大Aa(φ10～25mm)和巨大Aa Moyamoya disease is mainly caused by stenosis or occlusion of the bifurcation of the internal carotid artery (ICA) or the middle cerebral artery (MCA), the proximal cerebral artery (ACA) and the presence of isovascular blood vessels at the base of the brain, often occurring on both sides , Even seen in one side. The authors studied 76 patients with moyamoya disease and aneurysm (Aa), including age, gender, ethnicity, type of attack, number, size and location of Aa. According to the location of Aa is divided into main artery aneurysm (MAA) and peripheral aneurysms (PAA), according to the volume is divided into small Aa (φ1 ~ 9mm), large Aa (φ10 ~ 25mm) and huge Aa
