ICD-Code I65.8: Occlusion and stenosis of other precerebral artery
One of the arteries that supply blood to your brain has narrowed or become blocked.
Arteries are blood vessels that transport blood away from the heart. They supply all the tissue in the body with oxygen-rich blood. For example, the neck has several arteries that supply the brain. On the right side of the body, the artery at the neck comes from a vessel that also supplies the right arm. Smaller arteries in turn branch off from the large arteries in the neck. All these arteries can be affected by a narrowing or occlusion.
There are various reasons for an artery getting blocked. The artery can be narrowed by deposits of calcium and fats in the blood vessel wall. Then not enough blood can flow through. Or the artery can be blocked by a blood clot. Blood clots occur when components of the blood clump together. The blood clot can form in the heart or somewhere else in the body. The blood clot can then be swept towards the brain along with the blood.
Various risk factors can favor the blocking of an artery. These include, for example, smoking, obesity, and high blood pressure.
