What is vertebral artery?
The vertebral arteries (VA) are paired arteries, each arising from the respective subclavian artery and ascending in the neck to supply the posterior fossa and occipital lobes, as well as provide segmental vertebral and spinal column blood supply.
What causes vertebral artery blockage?
Atherosclerosis or “hardening of the arteries” is the main cause of vertebrobasilar disease. The narrowing of the vertebral or basilar arteries caused by atherosclerosis creates vertebrobasilar insufficiency (VBI), or an insufficient delivery of blood flow to the posterior structures of the brain.
What happens if the vertebral artery is damaged?
After the tear, blood enters the arterial wall and forms a blood clot, thickening the artery wall and often impeding blood flow. The symptoms of vertebral artery dissection include head and neck pain and intermittent or permanent stroke symptoms such as difficulty speaking, impaired coordination and visual loss.
What are the symptoms of vertebral artery occlusion?
Vertigo, dizziness, nausea, vomiting and head or neck pain are the most common initial symptoms reported. Other common signs and symptoms include weakness, hemiparesis, ataxia, diplopia, pupillary abnormalities, speech difficulties and altered mental status.
What does left vertebral artery do?
The vertebral artery delivers blood to the neck’s vertebrae, upper spinal column, the space around the outside of the skull. It also supplies blood to two very important regions of the brain: the posterior fossa and the occipital lobes.
How do you check vertebral artery?
Technique

- Perform passive rotation of the neck to the same side and hold for approximately 30 seconds.
- Repeat test with head movement to the opposite side.
Why is the vertebral artery important?
Can you live with an occluded vertebral artery?
Conclusions—Patients with symptomatic intracranial vertebral artery or basilar stenosis are at high risk of stroke, MI, or sudden death. Further studies are needed to clarify optimal therapy for these patients. Atherosclerotic stenosis of the major intracranial arteries is an important cause of ischemic stroke.

Where does the vertebral artery end?
It terminates by bifurcating into two posterior cerebral arteries. Each of these gives off the posterior communicating artery, which anastomoses with the middle cerebral artery, a branch of the internal carotid artery. This is how the communication between vertebral and internal carotid arteries is established.
