In this study, the authors present the results of 50 dissections of the anterior choroidal a. in man. Fifty cerebral hemispheres were prepared with the classic techniques of preservation and vascular injection. An ectopic origin was observed in 4% of cases. The intracisternal segment of the anterior choroidal a. forms a neurovascular bundle with the optic tract and basal v. Most of its intraparenchymatous branches arise from the cisternal segment, while branches supplying the optic tract, lateral geniculate body and thalamus arise from the intraplexual segment. Constant anastomoses exist with the vertebrobasilar system, specially the postero-lateral choroidal and posterior cerebral aa. We discuss the importance of an adequate knowledge of the anatomy of the anterior choroidal a. and its relations in the surgical approach to arterial aneurysms and arteriovenous malformations of the region.
在本研究中，作者展示了对50例人体脉络膜前动脉进行解剖的结果。采用经典的保存和血管注射技术制备了50个脑半球。在4%的病例中观察到异位起源。脉络膜前动脉的脑池段与视束和基底静脉形成神经血管束。其大部分脑实质内分支起源于脑池段，而供应视束、外侧膝状体和丘脑的分支起源于丛内段。与椎基底系统，特别是脉络膜后外侧动脉和大脑后动脉存在恒定的吻合。我们讨论了充分了解脉络膜前动脉的解剖结构及其在该区域动脉性动脉瘤和动静脉畸形手术入路中的关系的重要性。
