Abstract:
The vertebral artery arises from the first part of subclavian artery and courses within the bony canals of the cervical vertebrae, and then it lies on the upper surface of the posterior arch of the atlas before piercing the dura to enter the cranium. The intracranial part of the vertebral arteries unites at the caudal border of the pons to form the basilar artery. Vertebral artery contributes in supplying posterior part of the brain. In the present case, both the vertebral arteries had normal origin from the first part of subclavian artery. However, the cervical part of the right vertebral artery ascended through the transverse foramina of seventh cervical vertebrae and the left vertebral artery ascended through foramina of fifth cervical vertebrae. Incomplete knowledge of variations of the vertebral artery may lead to serious implications during surgical procedures such as transpedicular fixation technique which is safely performed at the seventh cervical vertebra, in which the vertebral artery is not usually present at the transverse foramen.
Key words: Vertebral artery, Transpedicular fixation technique, cervical vertebrae, foramen transversarium.
