Peripheral Lower Extremity Angiography

Lower extremity angiography is a diagnostic imaging test that allows doctors to view blood vessels throughout the body and diagnose blockages, enlargements, clots, and malformations. An angiogram to study the arteries is called an arteriogram; one to study the veins is called a venogram. Before the test, doctors inject a dye into the vessels to be imaged using a long, flexible, hollow tube called a catheter, which is usually introduced into the body through a needle puncture in the groin. The dye makes the blood vessels clearly visible on an X-ray image.
