Carotid Artery Stenting
Treatment of carotid artery stenosis using modern interventional radiology techniques.
The carotid artery is one of the main arteries that supply blood to the brain. Narrowing of this artery can occur due to the accumulation of fat and cholesterol on its inner wall, leading to reduced blood flow to the brain and increased risk of stroke.
The stenting procedure is performed under local anesthesia, where a catheter is inserted through a small incision in the groin and guided to the affected carotid artery.
Before placing the stent, a special filter device is used to prevent any small clots from reaching the brain. The artery is then expanded using a small balloon, after which a metal stent is placed to expand the artery and maintain blood flow.
This procedure is less invasive than traditional surgery and is characterized by a shorter recovery period and fewer complications.

Benefits
- Minimally invasive procedure without open surgery
- Shorter recovery period compared to traditional surgery
- Reduced risk of stroke
- Improved blood flow to the brain
- Fewer complications than open surgery
- Shorter hospital stay
Frequently Asked Questions
What is the carotid artery?
It is one of the main arteries in the neck that supplies blood to the brain. There are two carotid arteries, one on each side of the neck.
What are the symptoms of carotid artery stenosis?
Symptoms may not appear in early stages. In advanced cases, symptoms may include sudden weakness on one side of the body, difficulty speaking, or temporary vision loss.
How is carotid artery stenosis diagnosed?
Diagnosis is made through clinical examination, ultrasound, CT scan, or MRI of the arteries.
Who are suitable candidates for stenting?
Patients with severe carotid artery stenosis (70% or more) who may not be candidates for traditional surgery.
How long is the recovery period?
The recovery period is usually short, and patients can return to their normal activities within a week.
Are there any risks to the procedure?
Yes, there are some risks such as bleeding, blood clotting, or stroke, but they are less than the risks of traditional surgery.
Does the patient need follow-up after the procedure?
Yes, the patient needs regular imaging follow-up to ensure the stent is functioning properly and no new narrowing has occurred.
How long does the procedure take?
The procedure typically takes one to two hours.
Can carotid artery stenosis be prevented?
Yes, by controlling risk factors such as high blood pressure, diabetes, smoking, and high cholesterol.
Can the stent be removed after placement?
No, the stent remains in place permanently. It is designed to be compatible with the body and does not cause any problems.
