What happens during a venogram?

A venogram may be performed on an outpatient basis or as part of your stay in a hospital. Procedures may vary depending on your condition and your physician's practices.

Generally, the venogram follows this process:
  • You will be asked to remove your jewelry or other objects that interfere with the procedure.
  • You will be asked to remove clothing and will be given a gown to wear.
  • A pen may be used to mark various sites of pulses on the leg before the procedure. This will allow easier monitoring of the pulses after the procedure.
  • You will lie on your back on the x-ray table.
  • After cleansing the area, an intravenous (IV) line will be inserted into a vein in your foot.
  • An injection of contrast dye will be given. You may feel some effects when the dye is injected into the IV line. These effects include a flushing sensation, a brief headache, or nausea and/or vomiting. These effects usually last for a few moments. Also, let the physician know if you are having difficulty breathing, itching of the skin, or hives.
  • X-rays will be taken at timed intervals as the dye travels through the lower extremities.
  • A tourniquet may be placed on the extremity to control the speed of blood flow.
  • The intravenous site will be flushed with heparin/saline solution, and the needle will be removed from the vein.
  • A pressure dressing will be placed over the puncture site.
