Carotid stenosis is diagnosed using a carotid ultrasound, also known as a duplex Doppler scan. An ultrasound uses sound waves to determine whether an artery has a blockage or reduced blood flow.
A stroke from carotid stenosis is caused by narrowing of one or more of the arteries supplying the brain with oxygen-rich blood. The narrowing is caused by the buildup of plaque on the inner walls of arteries supplying the brain.
Alternate Names : Carotid stenosis, Stenosis - carotid
Definition
The carotid arteries provide the main blood supply to the brain. There carotid arteries are located on each side of your neck under the jawline.
Carotid stenosis: Abnormal narrowing of the carotid artery, often a preamble to a stroke.
Carotid stenosis; Stenosis - carotid
Causes
Carotid artery disease occurs when sticky, fatty substances called plaque build up in the inner lining of the arteries. See: Atherosclerosis (hardening of the arteries) ...
Extracranial carotid stenosis due to atherosclerosis
Veins
Peripheral veins: The peripheral veins are observed for varicosities, arteriovenous malformations (AVMs) and shunts, and overlying inflammation and tenderness due to thrombophlebitis.
Most people with carotid stenosis aren't aware of the condition until they have a transient ischaemic attack (TIA). A TIA is a powerful warning that a full stroke is pending, possibly within hours, days, weeks or months.
If you have carotid stenosis then you have an increased risk of having a stroke. Carotid stenosis means a narrowing of one of your carotid arteries due to atheroma.

For patients who have already had transient or mild stroke symptoms due to moderate carotid stenosis (50 to 69 percent), surgery reduces the 5-year risk of stroke or death by 6.5 percent.
In asymptomatic patients with documented high-grade carotid stenosis by duplex scan, most often a confirmatory test such as carotid MRA or cerebral angiography should be obtained.
The term carotid artery disease refers to the narrowing of the carotid arteries and can also be called carotid stenosis. Fatty substance buildup and cholesterol deposits, called plaque are the cause of the narrowing arteries.

Carotid endarterectomy is the standard treatment for carotid stenosis. It can reduce the risk of future strokes.
