The authors studied two cases of persistent axial artery of the lower limb, a classic but exceptional variation (42 cases in the literature). It is well explained by embryology and is a recapitulation of anatomy in the animal series. By the systematic study of the literature, we can isolate four distinct types: Type I: Complete axial artery, normal femoral artery. Type II: Id., but incomplete femoral artery, with two subdivisions: II a: Femoral artery is present but incomplete. II b: Femoral artery is absent. Type III: Axial artery only in the proximal zone. Type IV: Axial artery only in the distal zone. In these two last types, the femoral artery is complete. The I, III and IV types correspond to organogenetic perturbation at the stage 21 of Streeter. The type II implies a more early disturbance, prior to stage 18.
作者研究了两例下肢持续性轴动脉病例，这是一种典型但罕见的变异（文献中有42例）。胚胎学对此有很好的解释，并且是动物系列解剖结构的重演。通过对文献的系统研究，我们可以区分出四种不同类型：I型：完整的轴动脉，正常股动脉。II型：同样情况，但股动脉不完整，有两个亚类：II a：股动脉存在但不完整。II b：股动脉缺如。III型：仅在近端区域有轴动脉。IV型：仅在远端区域有轴动脉。在这最后两种类型中，股动脉是完整的。I、III和IV型对应于斯特里特第21阶段的器官发生扰动。II型意味着在第18阶段之前有更早的干扰。
