Carotid artery stenosis is the narrowing of carotid arteries on both sides of the neck that carry blood to the brain, face, and head. A condition called atherosclerosis builds up plaque within the arteries and decreases the blood flow, which causes carotid artery stenosis. If ignored, stenosis can lead to a stroke because it completely narrows the arteries that carry blood to the brain.
These factors increase the risk of developing carotid artery stenosis:
Some people with this condition may experience blurred vision, fainting, and dizziness, which indicate insufficient blood supply to the brain. Generally, the first sign of carotid artery stenosis is a stroke or transient ischemic attack (TIA) due to a blood clot in the blood vessel affected by atherosclerosis. When this clot gets dislodged, it can travel to the brain and plug up a smaller artery. This can be life-threatening. It can damage the section of the brain that is dependent on the blood vessel.
Symptoms of both a stroke and a TIA include:
Sudden numbness or paralysis (often on one side of the body)
TIA is a temporary occlusion of a small artery that lasts a few minutes without causing any lasting damage. However, it is considered a warning sign of carotid artery stenosis. A stroke causes permanent injury to the part of the brain due to a lack of blood supply, resulting in severe disability or death.
