On this page you will find everything you are looking for regarding carotid artery stenosis.
What is carotid artery stenosis?
The carotid arteries are the main blood vessels that carry blood and oxygen to the brain. When these arteries become narrowed, it is called carotid artery stenosis. The narrowing occurs due to atherosclerosis, which is the buildup of fatty substances, calcium, and other waste materials inside the lining of the artery.
Carotid artery stenosis is similar to coronary artery disease, where buildup occurs in the arteries of the heart and can cause a heart attack.
What are the symptoms of carotid artery stenosis?
Sometimes, the first sign of the disease is a transient ischemic attack (TIA) or a stroke.
It is a sudden and temporary loss of blood flow to an area of the brain. It usually lasts from a few minutes to an hour. Symptoms disappear completely within 24 hours, with full recovery.
When symptoms persist, it is a stroke. Symptoms of a transient ischemic attack or stroke may include the following:
● Sudden weakness or numbness in the arm or leg on one side of the body.
● Sudden paralysis of the arm or leg on one side of the body.
● Loss of coordination or movement.
● Confusion, decreased ability to concentrate, dizziness, fainting, or headache.
● Numbness or loss of sensation in the face or in the arm or leg.
● Temporary loss of vision or blurred vision.
● Inability to speak clearly or slurred speech.
What are the causes of carotid artery stenosis?
Atherosclerosis causes most cases of carotid artery stenosis. Fatty deposits accumulate along the inner layer of the arteries, forming plaques. Thickening leads to narrowing of the arteries and reduces blood flow or completely blocks blood flow to the brain.
In addition, there are risk factors that increase the likelihood of carotid artery stenosis, including:
● Older age.
● It is more common in males than in females.
● Family history.
● Genetic factors.
● High blood cholesterol.
● High blood pressure.
● Smoking.
● Diabetes.
● Overweight.
● Following a diet high in saturated fats.
● Lack of physical activity.
What are the diagnostic methods?
The doctor takes a medical history and performs a physical examination and may request additional procedures as needed, such as:
● Ultrasound imaging.
● Computed tomography angiography (CTA).
● Magnetic resonance angiography (MRA).
What are the treatment methods for carotid artery stenosis?
Treatment is carried out through several measures or as required and may include the following:
● Lifestyle changes to maintain blood sugar, blood pressure, and cholesterol levels within normal limits.
● Medications, such as:
○ Aspirin to help prevent blood clotting.
○ Medications to treat high harmful fats and cholesterol for prevention.
● Surgical or interventional treatment, including carotid stent placement and carotid endarterectomy.
What are the methods of preventing carotid artery stenosis?
Carotid artery stenosis can be prevented in the same way that heart disease is prevented. This includes:
● Following a healthy diet that includes plenty of fresh fruits and vegetables, lean meats such as poultry and fish, and low-fat or fat-free dairy products.
● Reducing salt, sugar, processed foods, saturated fats, and alcohol intake.
● Exercising, aiming for at least 40 minutes of moderate to vigorous physical activity 3 to 4 days per week.
● Controlling weight. If you are overweight, take steps to lose weight.
● Quitting smoking.
● Controlling stress. Learn how to manage stress at home and work.
What are the complications of carotid artery stenosis?
Stroke is one of the main complications of carotid artery disease. Stroke can cause serious disability and may be fatal.
When should you see a doctor?
If you feel or notice symptoms of a stroke, contact emergency services immediately or go to the nearest healthcare facility.
Frequently Asked Questions:
I have been diagnosed with carotid artery disease. Is it a chronic disease that cannot be treated?
Carotid artery disease is a chronic disease that cannot be cured permanently, but the carotid artery cannot be cured permanently, but the condition can be managed and complications prevented by adhering to preventive guidelines and medications under the supervision of the treating physician.
