Vertebral Artery: What Is It, Location, Anatomy and Function

Cleveland Clinic

A note from Cleveland Clinic

The vertebral arteries provide blood to the brain and spine, keeping the nervous system healthy. Vertebral artery stenosis, or vertebrobasilar insufficiency, is the result of plaque collecting in the arteries. The plaque makes the arteries narrow, slowing blood flow. This increases your risk for strokes, including TIAs. If you’re at risk for vertebral artery stenosis, you can make lifestyle changes to lower your stroke risk.
