An angiogram of the lower extremity is a test used to evaluate the blood vessels of the leg for blockages or narrowing. The test is performed by injecting a contrast dye into the arteries of the leg and then taking x-rays. The contrast dye makes the arteries visible on the x-rays.
The angiogram of the lower extremity is often used to evaluate for arterial disease.
What to Expect With a Lower Extremity Angiogram
The angiogram of the lower extremity is usually performed on an outpatient basis. This means that you will be able to go home after the procedure. The procedure takes about 30 minutes to 2 hours.
You will be asked to remove all clothing and jewelry from your waist down. You will be given a gown to wear during the procedure.
An IV will be started in your arm so that you can receive sedation during the procedure.
You will be positioned on the X-ray table and a special X-ray camera will be used to take pictures of your arteries.
A small incision will be made in your groin area and a catheter (a thin tube) will be inserted into an artery.
The contrast dye will be injected through the catheter and into your arteries.
The X-ray camera will take more pictures as the contrast dye moves through your arteries.
When the pictures are done, the catheter will be removed and pressure will be applied to stop any bleeding.
In most cases, you can go home the same day after the procedure, although sometimes your doctor will require you to stay in the hospital overnight.
