Venography

A venography is an X-ray imaging technique that uses contrast dye in order to see the veins in the body. Being able to monitor blood flow within the veins allows interventional radiologists to find blood clots, as well as get clear images of your veins before performing a procedure.

How to Prepare for a Venography

  • Plan to arrive one hour before your procedure. Blood test may be performed.
  • Do not eat or drink the morning of the procedure, as your stomach will need to be empty.
  • Inform the interventional radiology team of any allergies you have.
  • You may be asked to remove jewelry and other metal accessories.

What to Expect

  • You will lie on the X-ray table for a variable period of time, depending on the complexity. A small IV will be started to assess the problem area.
  • Contrast dye will be injected through the IV. This may feel warm throughout your body, but should not hurt.
  • If a local anesthetic is required, this will be injected through an IV in the arm.
  • Your interventional radiologist and a technologist will monitor the images generated as the venogram is performed.

What to Expect after a Venography

  • Images will be ready in minutes, and your interventional radiologist will discuss the results with your primary care or referring physician, who will contact you about next steps.
  • You will be able to leave the hospital after the procedure. Drinking fluids helps to flush out the contrast dye in your system.
