A venogram is an X-ray test that takes pictures as the blood flows through the veins in different areas of the body. Radiology dye is put into your veins so they can be seen clearly on an X-ray picture. The Radiologist looks at the condition of your veins and whether there is any clot present.

A venogram can be done to:

  1. Check the blood flow, the condition of the valves in the veins and to diagnose any strictures or clots.
  2. Find blood clots in the deep veins of your leg, arm or pelvis.
  3. Place a filter to prevent clots going to your lungs.
  4. Place a stent to widely open up the vein.
  5. Draw blood samples around an organ such as the kidney.
  6. Guide the placement of a special intravenous line used for long term medication or fluid treatment.
