Carotid artery disease occurs when the carotid arteries become narrowed or blocked.
The carotid arteries provide part of the main blood supply to your brain. They are located on each side of your neck. You can feel their pulse under your jawline.
Carotid stenosis; Stenosis - carotid; Stroke - carotid artery; TIA - carotid artery
Carotid artery disease occurs when fatty material called plaque builds up inside the arteries. This buildup of plaque is called hardening of the arteries (atherosclerosis).
The plaque may slowly block or narrow the carotid artery. Or it may cause a clot to form suddenly. A clot that completely blocks the artery can lead to stroke.
Risk factors for blockage or narrowing of the arteries include:
At early stages, you may not have any symptoms. After plaque builds up, the first symptoms of carotid artery disease may be a stroke or a transient ischemic attack (TIA). A TIA is a small stroke that doesn't cause any lasting damage.
Symptoms of stroke and TIA include:
Treatment options include:
You may have certain procedures to treat a narrowed or blocked carotid artery:
Because there are no symptoms, you may not know you have carotid artery disease until you have a stroke or TIA.
Major complications of carotid artery disease are:
Go to the emergency room or call the local emergency number (such as 911) as soon as symptoms occur. The sooner you receive treatment, the better your chance for recovery. With a stroke, every second of delay can cause more brain injury.
