If you were diagnosed with infrainguinal PAD (Peripheral Artery Disease), you are suffering from narrowing or blocking of artery (“atherosclerosis”) in your leg/s. Atherosclerosis is caused by the buildup of fatty and fibrotic material (called atherosclerotic plaques) on the walls of the artery, which narrows the artery in the leg, and results in a diminished blood supply to your leg. The narrowing could become a blockage at certain places along the artery. The blocked segment of the artery is called a lesion. PAD patients are usually suffering from symptoms related to the lack of blood supply to the affected leg muscles as a result of the presence of this lesion inside their artery. It mainly manifests as diminished walking capability in which one has to stop walking from time to time until the muscles can recover and remove the lactic acid that accumulated from lack of oxygen. This walking impairment is called claudication. The blood pressure in the affected areas is also reduced.
