Peripheral Stenting is one treatment option for addressing Peripheral Arterial Disease (PAD). PAD refers to the formation of atherosclerotic plaques, or lesions, on the inside of an artery. These plaques are composed of cholesterol, fatty deposits, and other substances. Over time, the plaques increase in size, progressively restricting the flow of blood through the artery. PAD in the arteries of the legs can lead to pain in the legs due to the reduced blood flow. Left untreated, PAD can progress to completely blocking blood vessels, which can lead to ulcers, tissue death, and gangrene.
