LAB TEST

Extremity angiography

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.

How the Test is Performed

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). During the test, your blood pressure, heart rate, and breathing will be checked. The health care provider will shave and clean an area, most often in the…

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: Aneurysms (abnormal widening or ballooning of part of an artery) Blood clots Other diseases of…

Risks

Complications may include: Allergic reaction to the contrast dye Damage to the blood vessel as the needle and catheter are inserted Excessive bleeding or a blood clot where the catheter is inserted, which can reduce blood flow to the leg Heart attack or stroke Hematoma, a collection of blood at the site of the needle…
