Abstract
This work is based on a study of 62 circles of Willis (circulus arteriosus cerebri) from patients dead from diverse causes. We have described the wide diversity of variations found to be present in the arterial vessels that form the circle, we presented the frequency of the different variations, and finally we discuss the possible ontogenic cause of these variations.
摘要
这项工作基于对62个来自因各种原因死亡患者的Willis环（脑动脉环）的研究。我们描述了构成该环的动脉血管中存在的广泛变异，给出了不同变异的频率，最后讨论了这些变异可能的个体发生原因。
