Abstract

This study was designed to study the microvascular anatomy of the basilar artery between the superior cerebellar artery and the vertebrobasilar junction (i.e. the lower basilar artery). Twenty unfixed brains were injected with silicone rubber solution and studied with a Zeiss OPMI microscope. The length of this segment of the basilar artery was 28.1 + 1.35 mm and its course was straight in 9 (45%) brains, curved in 7 (35%) and tortuous in 4 (20%). The total number of perforators found in 20 brains was 340 with an average of 17 per brain. Of these, 118 (34.7%) were median and 222 (65.2%) were lateral. Median branches had a mean length of 5.8 + 1.25 mm, whereas left and right lateral branches had a mean length of 16 + 1.25 mm and 16 + 1.58 mm respectively.

摘要

本研究旨在研究基底动脉在小脑上动脉与椎基底动脉交界处（即基底动脉下段）之间的微血管解剖结构。对20个未固定的大脑注入硅橡胶溶液，并使用蔡司OPMI显微镜进行研究。基底动脉这一段的长度为28.1 + 1.35毫米，其走行在9个（45%）大脑中是直的，在7个（35%）大脑中是弯曲的，在4个（20%）大脑中是迂曲的。在20个大脑中发现的穿支总数为340个，平均每个大脑17个。其中，118个（34.7%）为正中穿支，222个（65.2%）为外侧穿支。正中分支的平均长度为5.8 + 1.25毫米，而左侧和右侧外侧分支的平均长度分别为16 + 1.25毫米和16 + 1.58毫米。
