Abstract

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.

摘要

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。
