Carotid Artery Stenosis

Quick answer

Your carotid arteries run up either side of your neck and carry blood to your face, head and brain. In carotid artery stenosis, plaque builds up inside them and narrows the channel. It can close off completely. This happens slowly, and the first sign is often a stroke or a TIA. Sudden numbness, trouble speaking or seeing, dizziness or a severe headache means call 911.

Carotid artery stenosis, also known as carotid artery disease, is a narrowing or constriction of the carotid arteries on either side of the neck that carry blood to the head, face and brain. It is usually caused by the build-up of plaque within the arteries, a condition called atherosclerosis. Stenosis can worsen over time to completely block the artery, which may lead to stroke.

What is carotid artery stenosis?

Carotid artery stenosis occurs when fatty deposits (plaques) clog the blood vessels that deliver blood to your brain and head (carotid arteries). The blockage increases your risk of stroke, a medical emergency that occurs when the blood supply to the brain is interrupted or seriously reduced, depriving the brain of essential oxygen.

What are the symptoms of carotid artery stenosis?

Carotid artery stenosis develops slowly, and the first sign may be a stroke or transient ischemic attack (TIA). A TIA is a temporary shortage of blood flow to your brain. Signs and symptoms of a stroke or TIA include:

  • Sudden numbness or weakness in the face or limbs, often on only one side of the body
  • Sudden trouble speaking and understanding
  • Sudden trouble seeing in one or both eyes
  • Sudden dizziness or loss of balance
  • Sudden, severe headache with no known cause

Frequently Asked Questions

Do you still have questions about varicose veins? We answered some of the most common questions to address your concerns.

Do I Need to See a Doctor for Varicose Veins?

Yes, you should, especially if you’re experiencing leg pain, swelling, or skin discoloration. These symptoms may be signs of a more serious condition, like chronic venous insufficiency or even blood clots. A specially trained vein specialist can evaluate your veins and create a treatment plan to restore proper blood flow.

How to Treat Varicose Veins in Kids?

Though rare in children, they can develop varicose veins if there’s a family history of the condition. Most cases only require monitoring and healthy lifestyle changes. However, a specialist may suggest noninvasive treatments to prevent larger varicose veins from developing as the child grows.

What Is the Newest Procedure for Varicose Veins?

The latest treatments include laser ablation, radiofrequency therapy, and VenaSeal. These minimally invasive procedures close off faulty veins, allowing blood to flow more efficiently through healthier ones. They’re safer, faster, and more comfortable than traditional surgery, with quicker recovery times.

Does Insurance Cover Varicose Vein Treatment?

Your insurance will cover your vein treatment if it is deemed medically necessary. Varicose vein removal for cosmetic purposes is usually not covered. Always confirm with your provider before starting a treatment plan.

Can You Get Rid of Varicose Veins Without Surgery?

Yes, you can, especially if your varicose veins are mild to moderate. Non-surgical options like laser or radiofrequency treatments can close off damaged veins without the need for surgery. Combined with healthy habits, these can greatly reduce visible veins and prevent new ones from forming.
