Atherectomy/Angioplasty of Noncoronary Vessel

Atherectomy and angioplasty are methods that can be used to open arteries without surgery. There are several different devices that can be threaded through blood vessels to the site of a narrowing or blockage. These devices remove the obstruction so that blood flow is restored.

  • Call Your Doctor

    Depending on the site of your procedure, call your doctor if you experience the following:

    • Redness, swelling, increasing pain, excessive bleeding, or discharge at the point of catheter insertion
    • Signs of infection, including fever and/or chills
    • Extreme sweating, nausea, or vomiting
    • Leg or arm feels cold, turns white or blue, or becomes numb or tingly
    • Extreme pain, including chest pain
    • Difficulty breathing

    In case of an emergency, call for medical help right away.

  • What to Expect

  • Reasons for Procedure


    Most often, these procedures are done when an artery is narrowed by
    atherosclerosis, and there is no improvement with exercise or medication treatment. Also if the artery is too narrow, blood is no longer able to pass through. The body part then suffers from
    lack of oxygen, also called ischemia. This can cause different symptoms, depending on the part of the body that is not getting enough oxygen.

  • Possible Complications

    If you are planning to have an atherectomy or angioplasty, your doctor will review a list of possible complications, which may include:

    • The artery may close again after the procedure
    • Damage to the artery
    • Bleeding
    • Infection

    Before your procedure, talk to your doctor about ways to manage factors that may increase your risk of complications such as:

    • Smoking
    • Drinking
    • Chronic disease such as diabetes or obesity

    Your risk of complications may also be increased if you have blood clotting problems.
