What happens before an endovascular aneurysm repair (EVAR)?

Endovascular aneurysm repair (EVAR) is a minimally invasive (without a large abdominal incision) procedure performed to repair an abdominal aortic aneurysm -- a bulging, weakened area in the wall of the aorta (the largest artery in the body). Before the procedure:
  • Your physician will explain the procedure to you and offer you the opportunity to ask any questions that you might have about the procedure.
  • You will be asked to sign a consent form that gives permission to do the procedure. Read the form carefully and ask questions if something is not clear.
  • In addition to a complete medical history, your physician may perform a physical examination to ensure you are in good health before you undergo the procedure. You may also undergo blood tests and other diagnostic tests.
  • You will be asked to fast for eight hours before the procedure, generally after midnight.
  • If you are pregnant or suspect that you are pregnant, you should notify your physician.
  • Notify your physician if you are sensitive to or are allergic to any medications, latex, iodine, tape, contrast dyes, and anesthetic agents (local or general).
  • Notify your physician of all medications (prescribed and over-the-counter) and herbal supplements that you are taking.
  • Notify your physician if you have a history of bleeding disorders or if you are taking any anticoagulant (blood-thinning) medications, aspirin, or other medications that affect blood clotting. It may be necessary for you to stop these medications prior to the procedure.
  • If you smoke, you should stop smoking as soon as possible prior to the procedure, in order to improve your chances for a successful recovery from surgery and to improve your overall health status.
  • You may receive a sedative prior to the procedure to help you relax.
  • The areas around the surgical site may be shaved.
  • Based upon your medical condition, your physician may request other specific preparation.
Here's what happens before an endovascular aneurysm repair (EVAR, also called "stent grafting") begins:
  • A nurse will prepare the patch of skin, usually in your groin, where the catheters will be inserted.
  • You will have an IV (intravenous) line for medication. Blood may be taken for lab tests.
