Understanding Venogram
A venogram is a type of imaging procedure. It uses X-rays and a special dye to look at veins in your body. The dye is called a contrast material. An X-ray is a picture of the inside of your body. Low levels of radiation create the image.
Why a venogram is done
A venogram is often done to find blood clots in the veins. It can help diagnose deep vein thrombosis. This is a blood clot in a deep vein, often in your legs. It's also done to find other problems related to the veins. These include varicose veins, a vein defect, or the narrowing of a vein.
How a venogram is done
This procedure is often done on an outpatient basis. That means you can go home afterward. During the procedure:
-
You will lie down on an exam table. The table may tilt to help the dye move through your body.
-
You may be given medicine, so you don’t feel any pain.
-
A healthcare provider will put a catheter, or needle, into 1 of your veins. The location depends on which body part is being X-rayed.
-
They will inject the dye into your vein.
-
X-rays are taken as the dye moves through your body.
-
You may be asked to hold your breath during the procedure.
