Venography
Venography is a study of veins in the body. Contrast medium (x-ray dye) is injected into the veins. This helps the blood vessels show clearly on x-ray pictures. X-rays of the veins are then taken.
Before the Procedure
Follow any instructions you are given on how to prepare, including:
-
Do not eat or drink anything for
6 hours before the test. -
Tell the technologist what medications, herbs, or supplements you take; if you are, or may be, pregnant; or if you are allergic to contrast medium or other medications.
During the Procedure
-
You will change into a hospital gown and lie on an x-ray table.
-
An area of skin over the insertion site will be cleaned. Local anesthetic may be injected to numb the skin.
-
An IV (intravenous) line is put into a vein in the prepared area.
-
Contrast medium is injected through the IV into the vein.
-
You will be asked to keep still while x-rays are taken. The technologist will tell you when you can move.
-
The IV will be removed and the insertion site will be bandaged.
After the Procedure
-
Drink plenty of water to help flush the contrast medium from your body.
-
Care for the insertion site as directed.
-
Call your healthcare provider if you have fever or redness, pain, or swelling at the insertion site.
Potential Risks and Complications
-
Infection or bruising around the catheter insertion site
-
Problems due to contrast medium, including allergic reaction or kidney damage
-
Inflammation of the vein (phlebitis)
-
Worsening of clotting
-
Skin damage due to contrast fluid leaking from insertion site
