Abstract
|
|
|
|
We present a rare case of an aberrant right vertebral artery originated from the distal aortic arch. This issue has been incidentally detected on a preoperative CT angiography after a stabbing injury of the cervical spinal cord. Normally, the right vertebral artery originates from the right subclavian artery. Therefore, in this case report we will review the incidence and the embryological mechanism of this aberrant course of the right vertebral artery and we will discuss as well the clinical importance of this variation.
