The recurrent artery of Heubner (RAH) is a very fascinating artery for various reasons. The first one is its early development in the embryologic and phylogenic life. The second one is the discrepancy between its diameter and its functional importance and the last but not least reason is the many variations of origin and course of this artery.
For more than a century, numerous studies furnished important information about variations in origin, course, and parenchymal territory of the RAH. The most important anomaly concerning the RAH is the accessory middle cerebral artery and well-illustrates the complexity of its embryologic development.
For these reasons, authors provide a review of anatomical variations of this artery that could be encountered with a particular attention given to the history and embryological knowledge.
Heubner 回返动脉（RAH）是一条非常有趣的动脉，原因有很多。首先是其在胚胎和系统发育过程中的早期发育。其次是其直径与其功能重要性之间的差异，最后但同样重要的原因是这条动脉的起源和走行存在许多变异。
一个多世纪以来，大量研究提供了关于 RAH 起源、走行和实质区域变异的重要信息。与 RAH 相关的最重要的异常是副大脑中动脉，很好地说明了其胚胎发育的复杂性。
基于这些原因，作者对该动脉的解剖变异进行了综述，特别关注其历史和胚胎学知识。
