A peripheral angiogram is a way to look for blockages in the arteries supplying the legs in people with peripheral arterial disease. This is usually done by inserting a small tube (like a large IV) into the artery of the leg, and injecting contrast dye and use X-ray imaging to get images of the blood vessels.
If a blockage is found, this can be fixed in the same manner using balloons to stretch out the vessel, devices to cut out the plaque, and/or stents that provide scaffolding for the diseased arteries to maintain blood flow down the legs.
