• Endarterectomy


    Atherosclerosis is hardening of a blood vessel from a buildup of plaque. Plaque is made of fatty deposits, cholesterol, and calcium. It builds on the inside lining of arteries. This causes the artery to narrow and harden. As plaque builds up, it can slow and even stop blood flow.
    Endarterectomy is a surgery to remove this build-up and improve blood flow. Surgery is most often performed on:
    • Carotid arteries in the neck that supply blood to the brain (most common)
    • The aorta (the body's largest artery)—delivers blood from the heart and circulates it throughout the body
    • Iliac and femoral arteries of the legs
    • Renal arteries that supply the kidneys with blood

    Reasons for Procedure

    This surgery is done to remove the build-up of deposits and improve blood flow. After the surgery, the symptoms of reduced blood flow, such as stroke, digestive problems, and leg cramps should improve.

    Possible Complications

    If you are planning to have endarterectomy, your doctor will review a list of possible complications, which may include:
    • Bleeding
    • Stroke, particularly if the carotid arteries are involved
    • Blood clots
    • Adverse reaction to the anesthesia
    • Infection
    Before your procedure, talk to your doctor about ways to manage factors that may increase your risk of complications such as:
    Your risk of complications may also be increased if you have plaque build-up in other vessels.

    What to Expect

    Prior to Procedure

    Before the surgery, your doctor will:
    • Give you an exam to make sure that you are healthy enough for the surgery
    • Take images of your arteries
    Talk to your doctor about your medications. You may be asked to stop taking some medications up to one week before the procedure.
    In addition, you may be instructed to:
    • Avoid eating or drinking after midnight the night before the surgery.
    • Arrange for a ride home from the hospital.


    You may have:
    • General anesthesia—blocks any pain and keeps you asleep through the surgery; given through an IV
    • Local anesthesia—numbs an area of your body so that you stay awake through the surgery

    Description of the Procedure

    Incisions will be made over the diseased part of the artery. The location will depend on the artery that is being unblocked.
    In the abdomen and legs, the artery above the obstruction will be clamped during the repair. The lower half of the body can go without blood supply during the time it takes to do the surgery. If surgery is done on the neck, the blood around the surgical site may first be rerouted. This will keep blood going to the brain.
    The inside of the artery will be cleaned out. Care will be taken not to have small fragments of the deposits break off and flow downstream, causing stroke or arterial occlusion. After the artery is cleaned out, the artery and the skin will be closed with sutures or staples.

    How Long Will It Take?

    Several hours, depending on the severity of the disease

    How Much Will It Hurt?

    After surgery, there will be pain from the incisions. Ask your doctor about medication to help reduce discomfort.

    Average Hospital Stay

    This procedure is done in a hospital setting. The usual length of stay is one day to one week. You may need to stay longer if complications occur.

    Post-procedure Care

    At the Hospital
    While you are recovering at the hospital, you may receive the following care:
    • You will be monitored to make sure that you are not bleeding, clotting, or developing an infection.
    • You will also be monitored to make sure that your wound is healing properly and that your pain is managed.
    During your stay, the hospital staff will take steps to reduce your chance of infection such as:
    • Washing their hands
    • Wearing gloves or masks
    • Keeping your incisions covered
    There are also steps you can take to reduce your chances of infection such as:
    • Washing your hands often and reminding visitors and healthcare providers to do the same
    • Reminding your healthcare providers to wear gloves or masks
    • Not allowing others to touch your incisions
    At Home
    When you return home, you may need to:
    • Take blood thinners
    • Make dietary changes or work with a dietitian
    • Take care of the wound to prevent infection

    Call Your Doctor

    After you leave the hospital, contact your doctor if any of the following occurs:
    • Signs of infection, including fever and chills
    • Redness, swelling, increasing pain, excessive bleeding, or any discharge from the incision site
    • Persistent nausea or vomiting
    • Pain that you cannot control with the medications you have been given
    • Constipation or diarrhea
    • Inability to urinate
    • Lightheadedness
    • Severe headaches
    • Problems with speech or vision
    • Cough, shortness of breath, or chest pain
