The following steps will precede a venogram:

  • 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 your permission to do the test. Read the form carefully and ask questions if something is not clear.
  • Notify your physician if you have ever had a reaction to any contrast dye, or if you are allergic to iodine.
  • Notify your physician if you are sensitive to or are allergic to any medications, latex, tape, and anesthetic agents (local and general).
  • You may be asked to stop eating and/or drinking for at least four hours before the procedure.
  • Notify your physician if you are pregnant or suspect you may be pregnant.
  • 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 a sedative is given before or during the procedure, you may need to have someone drive you home afterwards.
  • Based upon your medical condition, your physician may request other specific preparation.
