A peripheral angiogram is a test that uses X-rays and dye to find narrowed or blocked areas in one or more arteries that supply blood to your legs.

The procedure usually starts with a needle put into the femoral (groin) artery. After access is established, catheters (thin tubes) and wires are threaded through the arterial system to a specific area of interest or throughout the entire body. As a contrast agent (iodine dye) is injected, X-ray images are taken to let your vascular surgeon view the flow of the dye and identify blockages.
