摘　　要：大脑中动脉(MCA)是颈内动脉(ICA)的最大、最复杂的末端分支,具有较大范围的供血分布区。MCA的先天变异相对少见,相应的类别也有部分存在不同的亚型。关于MCA变异的文献在国内外报道较少,且大多缺乏系统的论述和大样本量的研究。本文主要论述MCA常见变异及相关亚型的CTA的表现,以提高大家对该疾病的认识。Middle cerebral artery(MCA)is the largest and most complex terminal branch of internal carotid artery(ICA),which has a wide range of blood supply distribution.The congenital variation of MCA is relatively rare.A few reports about MCA variation are reported all around the world,and most of them are lack of systematic discussion and large sample size research.This article mainly discusses the common variants of MCA and the performance of CTA of related subtypes,which aims at raising everyone's awareness of the disease.
