Having Carotid Angioplasty and Stenting

Angioplasty and stenting is a type of procedure to improve the blood flow in an artery or vein. The carotid artery is a large artery in your neck. During the procedure, healthcare providers use a thin tube with a balloon at its tip to open up the artery. A tiny mesh tube called a stent is put into the artery. It is left in place to help keep the artery open. It is a minimally invasive procedure. This means it’s done with a small cut (incision).

What to tell your healthcare provider

Before the procedure, make sure to tell the medical team if you:

  • Have had any recent changes in your health, such as a fever

  • Are pregnant or might be pregnant

  • Are allergic to shellfish or iodine

  • Have ever had a bad reaction to contrast dye

  • Have ever had a problem with medicine that helps you relax (sedation)

Tests before your procedure

You may need some tests before the procedure, such as:

  • Blood tests, to check for anemia and infection

  • An electrocardiogram, to check your heart rhythm

  • A chest X-ray, to look at your heart and lungs

  • Ultrasound of your neck, to look at the carotid artery

  • CT angiogram of the blood vessels of your neck and head

Getting ready for your procedure

Talk with your healthcare provider about how to get ready for your procedure. Tell your healthcare provider about all the medicines you take. This includes over-the-counter medicines such as aspirin. You may need to stop taking some medicines ahead of time, such as blood thinners. If you smoke, you’ll need to stop before your procedure. Talk with your healthcare provider if you need help to stop smoking.

Do not eat or drink after midnight the night before your procedure. Your healthcare provider may give you more instructions about how to get ready.

On the day of your procedure

Talk with your healthcare provider about what to expect during your procedure. The procedure will likely be done by a doctor trained in vascular medicine and a team of specialized nurses. A typical procedure may go like this:

  • An IV will be put in your arm or hand before the procedure starts. You’ll be given sedation through the IV line. This will make you relaxed and sleepy during procedure.

  • Hair in the area of your procedure may be removed. The area may be numbed with a local anesthesia.

  • The doctor will make a small incision in a blood vessel in your groin. He or she will then put a long, thin wire into this cut. The wire acts as a guide during the procedure.

  • The doctor will then insert a thin, flexible tube (catheter) over the wire. It has a tiny deflated balloon on the end. The catheter will be threaded through the blood vessel all the way into the carotid artery in your neck. Continuous X-ray images may be used to show exactly where the catheter is.

  • The doctor will inflate the balloon inside the narrow part of the carotid artery. This will stretch the area open.

  • A mesh tube called a stent may be left in place in the area. This will help keep the area open.

  • The doctor will deflate the balloon. He or she will remove the catheter.

  • The doctor will close and bandage the incision site in the groin.

After your procedure

After the procedure, you will spend several hours in a recovery room. You may be sleepy and confused when you wake up. Your healthcare team will watch your vital signs, such as your heart rate and breathing. You’ll be given pain medicine if you need it.

You may need to lie flat without bending your legs for several hours after the procedure. This is to help prevent bleeding from the incision site. You may be able to go home the same day. Or you may need to stay in the hospital overnight. Your doctor will tell you more about what to expect. When you’re ready to go home, you’ll need to have a family member or friend drive you.

Recovering at home

Your doctor may prescribe medicines to help prevent blood clots or spasm of your blood vessels. Follow all of your healthcare provider’s instructions. This includes any advice about medicines, exercise, and wound care. You may have some pain after the procedure. You may notice a bruise where the catheter was inserted. You can take over-the-counter pain medicines if you need to. Get some rest and avoid strenuous exercise for at least 24 hours.

Follow-up care

If you had symptoms from your carotid stenosis, these should go away after the procedure. In follow-up appointments, your healthcare provider will talk with you about your continued care. This includes ways to lower your risk for atherosclerosis. You also may need follow-up blood tests or imaging of your neck.

When to call your healthcare provider

Call your healthcare provider right away if you have any of these:

  • Fever of 100.4°F (38.0°C) or higher

  • Swelling or pain at the incision site that gets worse

  • Fluid or blood leaking from the incision site

  • Redness or warmth at the incision site

  • Fever

  • Chest pain
