A peripheral angiogram is a test carried out to identify any blood vessel narrowing or blocked areas in the arteries supplying your pelvis, legs, knees, ankles and less frequently, your arms. The angiogram will determine whether there is any Peripheral Artery Disease (PAD). PAD can cause narrowings or blockages in your peripheral arteries causing pain, discomfort and tiredness (also referred to as claudication). The pain may disappear with rest.
