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.
Vertebrobasilar disease describes a broad spectrum of vascular abnormalities in the arterial supply to the brain stem. The vertebrobasilar circulation (VC, also called the posterior circulation) consists of the arterial supply to the brain stem, cerebellum , and occipital cortex. The vertebral arteries arise from the subclavian arteries in the neck.
