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.

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 relaxed (sedative) if you are anxious about the test.
The health care provider will shave and clean an area, usually in the groin.
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 - 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 - 48 hours.
You should not eat or drink anything for 6 - 8 hours before the test.
You may be told to stop taking certain medications 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 health care provider.
Make sure your health care provider knows about all the medicines you take, including those bought without a prescription. This includes herbs and supplements.
Tell your health care provider if you:
The x-ray table is hard and cold. You may want to ask for a blanket or pillow. You may feel some stinging when the numbing medicine is injected. You may also feel some pressure as the catheter is moved.
The dye can cause a feeling of warmth and flushing. This is normal and usually goes away in a few seconds.
You may have tenderness and bruising at the site of the catheter insertion after the test. Seek immediate medical help if you have:
Your doctor may order this test if you have symptoms of a narrowed or blocked blood vessel in the arms, hands, legs, or feet.
The test may also be done to diagnose:
The x-ray shows normal structures for the age of the patient.
An abnormal result is common due to narrowing and hardening of the arteries in the arms or legs due to plaque build-up (hardening of the arteries) in the artery walls.
The x-ray may show a blockage in the vessels caused by:
Abnormal results may also be due to:
Complications may include:
There is low-level radiation exposure. However, most experts feel that the risk of most x-rays is smaller than other risks we take every day. Pregnant women and children are more sensitive to the risks of the x-ray.
