Stenting involves placing a small metal coil (stent) in the clogged artery. The stent helps prop the artery open and decreases the chance of it narrowing again. Carotid angioplasty and stenting may be used when traditional carotid surgery (carotid endarterectomy)
isn’t possible
, or it’s too risky.

How long does a stent last in a carotid artery?
Once a stent is placed in a carotid artery, the stent
permanently stays inside the artery
. Once placed, the stent permanently stays inside the artery. There is a 2-3% risk of repeat narrowing if the stent also gets blocked in the future. This usually happens within the first 6-9 months.
What percentage of carotid artery blockage requires surgery?
If a carotid artery is narrowed from 50% to 69%, you may need more aggressive treatment, especially if you have symptoms. Surgery is usually advised for carotid
narrowing of more than 70%
.
Can carotid arteries be unclogged?
It involves making a tiny incision at the base of the neck and, from there, inserting a stent into the carotid artery. While the stent is being placed, blood flow through the carotid artery
is reversed temporarily
.
What is the success rate of carotid artery surgery?
What are the benefits? A carotid procedure may reduce the long-term risk of stroke from 2% per year to 1% per year. A procedure is most likely to benefit people who have
60% to 70% or more narrowing of the carotid arteries
.
Are you awake during carotid artery surgery?
Carotid endarterectomy is performed with local anesthesia, so
you are awake during the procedure
. It is easier for the doctor to monitor blood flow to the brain when you are awake, which helps him or her determine whether a tube called a shunt is needed.
How many years does a stent last?
How long will a stent last?
It is permanent
. There is just a 2–3 per cent risk of narrowing coming back, and if that happens it is usually within 6–9 months. If it does, it can potentially be treated with another stent.
Does having a stent shorten your life?
While the placement of stents in newly reopened coronary arteries has been shown to reduce the need for repeat angioplasty procedures, researchers from the Duke Clinical Research Institute have found that
stents have no impact on mortality over the long term
.
Do and don’ts after stent?
Don’t lift heavy objects
. Avoid strenuous exercise. Avoid sexual activity for a week. Wait at least a week before swimming or bathing.
What happens if you press too hard on the carotid artery?
Do not press on the carotid artery on both sides of your neck at the same time. This may cause
you to feel lightheaded or dizzy, or possibly faint
. Apply just enough pressure so you can feel each beat. Do not push too hard or you will obstruct the blood flow.
What dissolves artery plaque?
HDL
is like a vacuum cleaner for cholesterol in the body. When it’s at healthy levels in your blood, it removes extra cholesterol and plaque buildup in your arteries and then sends it to your liver. Your liver expels it from your body. Ultimately, this helps reduce your risk of heart disease, heart attack, and stroke.
Is 50 blockage of carotid artery bad?
With a low surgical risk, carotid endarterectomy provides modest benefit in symptomatic patients with carotid artery stenosis of 50 to
69 percent
. Platelet anti-aggregants and risk factor modification are recommended in symptomatic patients with less than 50 percent stenosis.
Does aspirin reduce plaque in arteries?
Now, a team led by a University of Florida Health researcher has found that
aspirin may provide little or no benefit for certain patients
who have plaque buildup in their arteries. Aspirin is effective in treating strokes and heart attacks by reducing blood clots.
Can you live with only one carotid artery?
Many people function normally with one
completely blocked carotid artery
, provided they haven’t had a disabling stroke. If narrowing hasn’t caused complete blockage, then a revascularization procedure may be warranted.
Does your neck hurt when your carotid artery is blocked?
It is linked with physical changes that can happen in a carotid artery in your neck. Your
neck may feel tender in
the area of the artery. The pain often goes up the neck to the jaw, ear, or forehead.
