What is the definition or description of: carotid artery stenosis?

Blockage of carotid: Stenosis mean blockage or tightness. So carotid artery stenosis means a blockage of the carotid artery. The treatment can involve medicines, stents, or surgery (called an endarterectomy). Which treatment is chosen depends on the degree of stenosis, symptoms, and overall health of the patient.

Stenosis: Carotid artery stenosis is the diameter of the artery is smaller than size of other position, such as rust inside if pipe. If the stenosis less than 60 % may not flow limiting to repair.

Narrowing of artery: Narrowing of the carotid( in the neck and leads to the brain). The carotid branches below the jaw to give the internal carotid flow to the brain and the external carotid and its branches to face and other tissue. The narrowing is commonly from atherosclerotic plaque buildup at the branch point.

Artery blockage: Carotid artery stenosis means that the carotid arteries have blockage, usually in the form of atherosclerosis. This can cause stroke. The more severe the blockage, the greater the risk in the absence of neurological symptoms, most cases can be handled with medicine and close periodic follow up by a vascular surgeon. However, if the blockage is more than 80%, surgery will reduce the stroke risk.
