The vertebral artery is a major artery of the neck that passes through the cervical vertebrae. There are two vertebral arteries, one on each side, and each branches off from the subclavian artery. They merge to form the single basilar artery at the base of the brain.
Vertebral artery stenosis is not rare. Even though it is in a rather similar location and may also result in stroke, vertebral artery stenosis is different from carotid artery stenosis. The vertebral arteries usually arise from the first portion of the subclavian artery.
