Carotid endarterectomy (CEA) is a surgery done to remove plaque (fatty deposits) from inside your carotid artery. The carotid artery is a blood vessel found in both sides of your neck. Plaque may build up inside your carotid artery and decrease blood flow to your brain. A piece of plaque may also break free and cause a stroke.

Drugs used to treat this and similar conditions

Medicines:

You may need any of the following:

• Aspirin helps thin the blood to keep blood clots from forming. If you are told to take aspirin, do not take acetaminophen or ibuprofen instead. Do not take more or less aspirin than directed. This medicine makes it more likely for you to bleed or bruise.
• Blood thinners help prevent blood clots. Clots can cause strokes, heart attacks, and death. Many types of blood thinners are available. Your healthcare provider will give you specific instructions for the type you are given. The following are general safety guidelines to follow while you are taking a blood thinner:
  • Watch for bleeding and bruising. Watch for bleeding from your gums or nose. Watch for blood in your urine and bowel movements. Use a soft washcloth on your skin, and a soft toothbrush to brush your teeth. This can keep your skin and gums from bleeding. If you shave, use an electric shaver. Do not play contact sports.
  • Tell your dentist and other healthcare providers that you take a blood thinner. Wear a bracelet or necklace that says you take this medicine.
  • Do not start or stop any other medicines or supplements unless your healthcare provider tells you to. Many medicines and supplements cannot be used with blood thinners.
  • Take your blood thinner exactly as prescribed by your healthcare provider. Do not skip a dose or take less than prescribed. Tell your provider right away if you forget to take your blood thinner, or if you take too much.
• Blood pressure medicine helps keep your blood pressure under control. This will protect your surgery site from breaking open.
• Cholesterol medicine helps lower the amount of cholesterol in your blood. It may help decrease new plaque from forming in your carotid artery.
• Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell your provider if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Warning signs of a stroke:

The word F.A.S.T. can help you remember and recognize warning signs of a stroke.

• F = Face: One side of the face droops.
• A = Arms: One arm starts to drop when both arms are raised.
• S = Speech: Speech is slurred or sounds different than usual.
• T = Time: A person who is having a stroke needs to be seen immediately. A stroke is a medical emergency that needs immediate treatment. Some medicines and treatments work best if given within a few hours of a stroke.

Self-care:

• Carefully wash the surgery area with soap and water. Dry the area and put on new, clean bandages as directed. Change your bandages if they get wet or dirty.
• Do not lift anything heavy until your healthcare provider says it is okay. This may be for a few weeks after surgery.
• Ask when you can return to your regular daily activities. Your provider will tell you when you can go back to work, drive, or do other activities.

Manage or prevent carotid artery or heart disease:

• Manage any other health conditions. Health conditions such as diabetes or high blood pressure or cholesterol levels can increase your risk. Your healthcare providers can help you manage any health conditions you have.
• Eat a variety of healthy foods. Healthy foods include fruit, vegetables, whole-grain breads, low-fat dairy products, lean meat, and fish. Choose fish that are high in omega-3 fatty acids, such as salmon and fresh tuna. Ask your provider for more information on a heart healthy diet and the DASH eating plan.
• Limit sodium (salt). Sodium may increase your blood pressure. Add less table salt to your foods. Read food labels and choose foods that are low in sodium. Your provider may suggest you follow a low-sodium diet.
• Reach or maintain a healthy weight. Extra weight makes your heart work harder. Ask your provider what a healthy weight is for you. Your provider can help you create a safe weight-loss plan, if needed.
• Exercise as directed. Exercise helps improve heart function and can help you manage your weight. Exercise can also help lower your cholesterol and blood sugar levels. Try to be active every day. Your provider can help you create an exercise plan that works best for you.
• Limit alcohol. Alcohol can increase your blood pressure and triglyceride levels. Men should limit alcohol to 2 drinks per day. Women should limit alcohol to 1 drink per day. A drink of alcohol is 12 ounces of beer, 5 ounces of wine, or 1½ ounces of liquor.
• Do not smoke. Nicotine and other chemicals in cigarettes and cigars can cause heart and lung damage. Ask your provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your provider before you use these products.
