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 the insides of the arteries. Arteries are blood vessels that carry blood away from the heart.
This test is done in a hospital or specialized procedure unit. 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:
After the x-rays or treatments are finished, the catheter is removed. Pressure is applied to the puncture site for 20 to 45 minutes to stop the bleeding. After that time, the area is checked and a tight bandage is applied. The arm or leg where the needle was placed is most often kept straight for another 6 hours after the procedure. You should avoid strenuous activity, such as heavy lifting, for 24 to 48 hours.
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.
Make sure your provider knows about all the medicines you take, including those you bought without a prescription. This includes herbs and supplements.
Tell your 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 most often 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:
You may need 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 your age.
An abnormal result is commonly due to narrowing and hardening of the arteries in the arms or legs from plaque buildup (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 for most x-rays is low compared with benefits. Pregnant women and children are more sensitive to the risks for the x-ray.
