Carotid artery stenosis

Average cost for this surgery is usually between USD 4050 to USD 4950.

It may vary based on the patient's condition and preferences.

Carotid artery stenosis refers to the narrowing or constriction of one or both of the carotid arteries, which are major blood vessels located in the neck. These arteries supply oxygenated blood to the brain. Stenosis occurs when there is a buildup of plaque (atherosclerosis) on the inner walls of the arteries, reducing blood flow to the brain.

Causes of carotid artery stenosis include:

Atherosclerosis: The most common cause, atherosclerosis is the buildup of fatty deposits (plaque) on the inner walls of the arteries over time. This can lead to narrowing and stiffening of the arteries.

Arterial dissection: A tear in the inner lining of the artery can lead to the formation of a blood clot, causing stenosis.

Fibromuscular dysplasia: An uncommon condition where there is abnormal growth or development of the arterial wall.

The narrowing of the carotid arteries can result in reduced blood flow to the brain, and in severe cases, it may lead to a stroke. When blood flow is significantly compromised, a piece of the plaque or a blood clot can break loose and travel to the brain, causing a blockage and subsequent stroke.

Symptoms of carotid artery stenosis may not be apparent until it reaches an advanced stage. However, some people may experience warning signs, including:

• Transient Ischemic Attacks (TIAs): Also known as mini-strokes, TIAs are brief episodes of stroke-like symptoms that resolve on their own. They can serve as a warning sign of potential stroke.
• Speech difficulties
• Visual disturbances
• Weakness or numbness on one side of the body

Diagnostic tests for carotid artery stenosis may include:

Ultrasound: Doppler ultrasound can visualize blood flow and detect the presence of plaque in the carotid arteries.

Angiography: This involves injecting a contrast dye into the blood vessels and taking X-ray images to visualize blood flow and any blockages.

CT or MRI scans: These imaging techniques can provide detailed images of the blood vessels and surrounding structures.

Treatment options for carotid artery stenosis may include:

Lifestyle changes: Managing risk factors such as high blood pressure, high cholesterol, and diabetes through lifestyle modifications.

Medications: Antiplatelet drugs (aspirin, clopidogrel) or anticoagulants may be prescribed to prevent blood clot formation.

Carotid endarterectomy: A surgical procedure to remove the plaque from the carotid artery.

Carotid angioplasty and stenting: A minimally invasive procedure where a stent is placed to open the narrowed artery.

The choice of treatment depends on factors such as the degree of stenosis, the patient's overall health, and the presence of symptoms.
