Microdissection of 100 hemispheres from human cadavers were performed in order to study the anatomic characteristics of the anterior choroidal artery (AChA). One AChA per hemisphere was found. In 98% of hemispheres the AChA arose from the internal carotid artery (ACI) 2.4mm distal to the origin of the posterior communicating artery (ACoP) and 4.7mm proximal to the carotid bifurcation. One or more perforating branches arose from communicating segment of ACI in 29% of hemispheres. The average calibre of the cisternal portion was 0.9mm and the plexal portion 0.7mm. The most frequent branches of the cisternal portion pass to the optic tract, cerebral peduncle, uncus and lateral geniculate body. Anastomosis were found between branches of the AChA and posterior cerebral artery, ACoP, middle cerebral artery and ACI. The results are discussed.
为研究脉络膜前动脉（AChA）的解剖学特征，对100个取自人类尸体的大脑半球进行了显微解剖。每个半球发现一条AChA。在98%的半球中，AChA发自颈内动脉（ACI），位于后交通动脉（ACoP）起点远端2.4mm处，颈动脉分叉近端4.7mm处。29%的半球中，一条或多条穿支发自ACI的交通段。脑池段的平均管径为0.9mm，丛状段为0.7mm。脑池段最常见的分支通向视束、大脑脚、钩和外侧膝状体。发现AChA的分支与大脑后动脉、ACoP、大脑中动脉和ACI之间存在吻合。对结果进行了讨论。
