Venogram

A venogram is a procedure performed to look at the veins using X-ray and contrast (dye). Contrast helps the veins show up on X-rays. A venogram evaluates vein abnormalities, identifies clots within veins and evaluates swelling in a limb.

LET YOUR CAREGIVER KNOW ABOUT:

  • All allergies, especially to medicines, shellfish, iodine and contrast.

  • All medications that you are taking, including prescription and over-the-counter medicines, dietary supplements, vitamins and herbal preparations.

  • Any previous complications from this or other procedures.

  • Any smoking history.

  • Any possibility of pregnancy.

  • Any history of bleeding problems.

  • Any other health problems, especially diabetes or kidney problems.
