Calcarine Artery Disorders

The calcarine artery is a crucial blood vessel in the brain, responsible for supplying blood to the primary visual cortex, a part of the brain essential for processing visual information. Disorders related to this artery can have significant impacts on vision and overall brain function.

Types of Calcarine Artery Disorders

1. Calcarine Artery Occlusion: A blockage in the artery that can lead to visual disturbances or loss.
2. Aneurysm: A bulge in the artery wall that can burst, leading to a stroke.
3. Arteritis: Inflammation of the artery, which can reduce blood flow and damage tissues.
4. Arteriovenous Malformation (AVM): An abnormal connection between arteries and veins in the brain, which can affect blood flow.
5. Thrombosis: Formation of a blood clot within the artery, impeding blood flow.
6. Stenosis: Narrowing of the artery, which can restrict blood supply.
7. Dissection: A tear in the artery wall, leading to blood leakage and possible clot formation.
8. Hemorrhage: Bleeding from the artery, potentially causing a stroke.
9. Ischemia: Reduced blood flow leading to tissue damage.
10. Embolism: A clot or debris traveling to and blocking the artery.
11. Vasculitis: Inflammation of the blood vessels affecting the calcarine artery.
12. Moyamoya Disease: Progressive narrowing of the arteries in the brain, including the calcarine artery.

14. Fibromuscular Dysplasia: Abnormal growth of cells in the artery walls, causing narrowing or aneurysms.
15. Atherosclerosis: Buildup of plaques in the artery, leading to reduced blood flow.
16. Cerebral Amyloid Angiopathy: Accumulation of amyloid proteins in the artery walls, increasing the risk of hemorrhage.
17. Hypertensive Encephalopathy: Brain dysfunction due to high blood pressure affecting cerebral arteries.
