In this article, we present 5 cases of uncommon anomalous vertebral arteries and discuss the possible embryologic etiologies. These cases include a left vertebral artery as the 2nd branch off the left subclavian, a left vertebral artery with 2 origins, a right vertebral artery arising as the last branch off the aorta, a right vertebral artery arising as the 2nd branch off the right subclavian artery, and right vertebral artery with proximal duplication as the 2nd branch off the right subclavian artery.
在本文中，我们展示了5例不常见的椎动脉异常病例，并讨论了可能的胚胎学病因。这些病例包括作为左锁骨下动脉第二分支的左椎动脉、有两个起源的左椎动脉、作为主动脉最后分支发出的右椎动脉、作为右锁骨下动脉第二分支发出的右椎动脉，以及作为右锁骨下动脉第二分支且近端重复的右椎动脉。
