A Peripheral Doppler is a non-invasive test that may suggest a blockage in arteries (blood vessels) in the arms or legs. If a blockage is suspected it may then be necessary to directly visualize the inside of these arteries. This is called an Angiogram.
Common symptoms that suggest blockage include pain or cramping of the legs or thighs while walking, early fatigue of the legs or arms with use, or in extremely severe cases pain at rest with discoloration of the limbs or none healing ulcers.
The obstructed vessel may be able to be opened with the goal of eliminating or improving symptoms. This is called Stenting.
