Extremity angiography

Definition

Extremity angiography is a test used to see the arteries in the hands, arms, feet, or legs. It is also called peripheral angiography.

Angiography uses x-rays and a special dye to see inside the arteries. Arteries are blood vessels that carry blood away from the heart.

How the Test is Performed

This test is done in a hospital. You will lie on an x-ray table. You may ask for some medicine to make you sleep and relax (sedative).

Certain treatments can be done during this procedure. These treatments include:

The health care team will check your pulse (heart rate), blood pressure, and breathing during the procedure.

The catheter is removed when the test is done. Pressure is placed on the area for 10 to 15 minutes to stop any bleeding. A bandage is then put on the wound.

The arm or leg where the needle was placed should be kept straight for 6 hours after the procedure. You should avoid strenuous activity, such as heavy lifting, for 24 to 48 hours.

How to Prepare for the Test

You should not eat or drink anything for 6 to 8 hours before the test.

You may be told to stop taking certain medicines, such as aspirin or other blood thinners for a short while before the test. Never stop taking any medicines unless told to do so by your provider.

You may have tenderness and bruising at the site of the catheter insertion after the test. Seek immediate medical help if you have:

What Abnormal Results Mean

Risks

Complications may include:

There is low-level radiation exposure. However, most experts feel that the risk for most x-rays is low compared with benefits. Pregnant women and children are more sensitive to the risks for the x-ray.
