Treating Carotid Artery Stenosis with Stents Sometimes a patient is not a candidate for carotid endarterectomy. This can help because of his or her general health. It can also happen is the narrow portion of the artery is too high up the neck to reach with surgery. In these cases, a stent can be placed in the carotid artery.
Procedures
Carotid endarterectomy: Severe cases of stenosis often require carotid endarterectomy. A surgeon makes an incision to remove plaque and any diseased portion of the artery while the patient is under general anesthesia. Carotid artery angioplasty and stenting: A less invasive option used for severe stenosis. During this procedure, the doctor threads a catheter from an incision …

For most patients, a carotid endarterectomy is the safest procedure to treat carotid artery stenosis. This is a surgical procedure during which the artery is opened in the neck and the plaque is cleaned out. The surgery is very effective at lowering your risk of stroke.
Nutrition
During the angioplasty procedure, a carotid stent (a small, metal mesh tube) is placed inside the carotid artery at the site of the blockage and provides support to keep the artery open. The stent stays in place permanently and acts as a scaffold to support the artery and keep it open. After several weeks, the artery heals around the stent.

Where are the carotid arteries located?
There are two carotid arteries (one on each side of the neck) that supply blood to the brain. The carotid arteries can be felt on each side of the lower neck, immediately below the angle of the jaw. The carotid arteries supply blood to the large, front part of the brain, where thinking, speech, personality and sensory and motor functions reside.
Which arteries supply blood to the brain?
The carotid arteries supply blood to the large, front part of the brain, where thinking, speech, personality and sensory and motor functions reside. The vertebral arteries run through the spine and supply blood to the back part of the brain (the brainstem and cerebellum).
What happens when plaque builds up in the carotid artery?
Plaque buildup can lead to narrowing or blockage in the carotid artery which, when significant, can put an individual at increased risk for stroke.

What is the most common procedure for carotid artery disease?
Carotid endarterectomy is the most commonly performed surgical treatment for carotid artery disease. During carotid endarterectomy, the surgeon reduces the risk of stroke from the operation by shunting (using a plastic tube to re-route blood flow to the brain) and monitoring the patient carefully.
What is carotid stenting?
For patients who meet certain eligibility criteria, carotid stenting offers an alternative approach to repairing the blockage in the artery. Carotid stenting is approved as a carotid artery disease surgical treatment for patients who are experiencing symptoms, have a carotid artery that is blocked 70 percent or more, and for whom surgery would be high risk. Some examples of patients who might benefit from this approach as opposed to carotid endarterectomy include patients who have had prior surgery or radiation surgery in the neck.
