Posterior Circulation Atherosclerosis

Posterior circulation atherosclerosis refers to the buildup of plaque (a fatty substance) in the arteries that supply blood to the back part of the brain. This condition can lead to serious health problems, including strokes. Understanding its types, causes, symptoms, diagnostic tests, treatments, and prevention is crucial for managing and preventing complications.

Types of Posterior Circulation Atherosclerosis

1. Vertebral Artery Stenosis: Narrowing of the arteries that run along the spine to the brain.
2. Basilar Artery Stenosis: Narrowing of the main artery at the base of the brain.
3. Posterior Cerebral Artery Stenosis: Narrowing of arteries that supply the back part of the brain.
4. Intracranial Atherosclerosis: Plaque buildup inside the arteries within the brain.
5. Subclavian Steal Syndrome: A condition where blood is diverted away from the brain due to narrowed subclavian artery.
6. Cerebral Small Vessel Disease: Affects the small arteries within the brain.
7. Diffuse Atherosclerosis: Plaque buildup in multiple arteries of the posterior circulation.
8. Acute Posterior Circulation Stroke: A sudden blockage in the arteries of the posterior circulation.
9. Chronic Ischemic Posterior Circulation Disease: Long-term reduction of blood flow to the back of the brain.
10. Atheromatous Plaque with Calcification: Hardening of the plaque in the arteries.

Causes of Posterior Circulation Atherosclerosis
