A venogram is a test that lets your doctor see the veins in your body, especially in your legs. A special dye is injected that can been seen on an X-ray. The dye lets your doctor see howyou’re your veins are and how healthy they are.
A venogram is one of the better tests use to diagnose deep vein thrombosis (DVT). This test can also help your doctor diagnose other health problems.
A venogram can be done in several ways:
X-rays use a small amount of radiation to create images of your bones and internal organs. X-rays are most often used to detect bone or joint problems, or to check the heart and lungs. A venogram is one type of X-ray.
A venogram is done with X-rays, which use a small amount of radiation. Talk with your healthcare provider about the amount of radiation used and any risks that apply to you.
Consider writing down all X-rays you get, including past scans and X-rays for other health reasons. Show this list to your provider. The risks of radiation exposure may be tied to the number of X-rays you have and the X-ray treatments you have over time.
Tell your provider if you are pregnant or think you may be pregnant. Radiation exposure during pregnancy may lead to birth defects.
Because contrast dye is used, there is a risk for allergic reaction to the dye. Tell your healthcare provider if you are allergic to or sensitive to any medicines, contrast dye, or iodine.
Tell your provider if you have:
You may not be able to have a venogram if you are allergic to the contrast dye, or have severe congestive heart failure or severe pulmonary hypertension.
You may have other risks depending on your specific health condition. Be sure to talk with your provider about any concerns you have before the procedure.
Some things may make your venogram less accurate. These include:
You may have the venogram done as an outpatient or as part of your stay in a hospital. The way the test is done may vary depending on your condition and your healthcare provider's practices.
Generally, a venogram follows this process:
After the procedure, the medical team will watch your heart rate, breathing rate, and blood pressure. They will also check the pulses in your feet, as well as the temperature, color, and sensation in your legs. They will watch the injection site for redness, warmth, swelling, and tenderness.
You can go back to your normal activities and diet as directed by your healthcare provider.
Drink plenty of fluids to keep from getting dehydrated. This will also help the contrast dye to leave your body.
Call your healthcare provider right away if you have any of these:
Your healthcare provider may give you additional instructions, depending on your situation.
