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.
The vertebral artery test is used to test the vertebral artery blood flow, searching for symptoms of vertebral artery disease. A reduction of blood flow may result in a transient ischiamic attack (TIA), a critical harbinger of impending stroke.
