PURPOSE 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. METHODS 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. CONCLUSION 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复发性动脉的胚胎学和变异。

目的出于多种原因，Heubner（RAH）的复发性动脉非常引人入胜。第一个是它在胚胎和系统发育生活中的早期发展。第二个原因是其直径与功能重要性之间的差异，最后但并非最不重要的原因是该动脉的起源和走向的许多变化。方法一个多世纪以来，许多研究提供了有关RAH起源，病程和实质区域变化的重要信息。关于RAH的最重要异常是大脑中部副动脉，充分说明了其胚胎发育的复杂性。结论由于这些原因，
