What is Carotid Artery Stenosis

In this article, you will learn about what is carotid artery stenosis.

There are basically two carotid arteries which are traveling through the left and right of the neck are greatly deliver blood to the head.

In the upper side of the neck, the common carotid artery divides into the basically external carotid artery that supplies excessive blood to the face. In this internal carotid artery supply blood to the brain.

In this, there would be an atherosclerotic plaque that can build up in the wall of the carotid artery. In this commonly carotid artery splits into an internal and external carotid artery.

When plaque is narrow around the artery when it is called to be an artery stenosis.

Carotid artery stenosis increases the greater risk of having a stroke. The degree of stenosis or a narrow artery has greatly related the risk of having a stroke.

Stroke basically happens when there is sudden decreased blood flow around the brain and forming to be a huge plaque. Plaque is broken into smaller pieces and block the smaller brain arteries.

If you diagnosed with carotid artery stenosis then should be evaluated by a neurosurgeon and specialized for this disorder.

Risk Factors for Carotid Artery Stenosis


-Advanced Age

-High Blood Pressure of Body (Hypertension)

-High Cholesterol (Also Called to be Hypercholesterolemia)

-Symptoms of Carotid Artery Stenosis

-Weakness and Numbness in Body

-Vision Loss in One Eye

-Speech Problems in the Body

Diagnosis of Carotid Artery Stenosis


Carotid Ultrasound:

This noninvasive test basically uses the sound waves to evaluate the blood flow in our body.

CT Scan of the Neck

It is a special kind of CT scan that basically evaluates the arteries in the neck.

MRI (Magnetic Resonance Imaging)

This test uses the powerful magnet that use the magnetic resonance to visualize the neck arteries.


It is basically a catheter-based procedure in which X rays are to be taken for which dye is injected into the arteries.

Treatment For Carotid Artery Stenosis

The treatment is done to improve the restore the blood flow which may also include angioplasty, vascular stenting or in serious cases surgery.

  • Carotid Endarterectomy

It is the most common treatment for the serious carotid artery disease. When making an incision along the front of your neck then surgeons open the affected artery and then removes the plaques.

The surgeons remove the plaque or repaired with either stitches or a graft.

  • Carotid angioplasty and stenting

If the blockage is serious and too difficult to reach with carotid endarterectomy or person don’t want a surgery.

Then, in this case, surgeons give local anesthesia and a tiny balloon is threaded by catheter to the area of the affected clog.

The balloon is also inflated in the artery to widen the artery and also inserted mesh coil to keep the artery from narrowing again.

Well, this was the end of the article of effective treatment to diagnose Carotid Artery Stenosis. In carotid arterial stenosis, recent advances in technology have made angioplasty and stenting possible in these patients.

Earlier diagnosis is necessary for the effective treatment of the disease.
