Carotid artery disease is also called carotid artery stenosis. The term refers to the narrowing of the carotid arteries. This narrowing is usually caused by the buildup of fatty substances and cholesterol deposits, called plaque. Carotid artery occlusion refers to complete blockage of the artery.
When the arteries become narrowed, the condition is called carotid stenosis. A blockage in your carotid artery can reduce the blood supply to your brain. A stroke can occur if your brain does not get enough blood. There are two invasive ways to treat a carotid artery that is narrowed or blocked. One is surgery called endarterectomy. The other is a procedure called carotid angioplasty with stent placement. Source(s): http://en.wikipedia.org/wiki/Cerebral_hy...
