I70: Atherosclerosis

I70.2: Atherosclerosis of arteries of extremities

Atherosclerosis of arteries of extremities is a specific subtype of atherosclerosis, a condition where plaque, which is made up of fat, cholesterol, calcium, and other substances found in the blood, build up inside the arteries over many years. In this case, the buildup happens specifically in the arteries that supply the extremities, including arms and legs. As the plaque builds up, it can narrow the artery, reducing blood flow to the affected extremity, potentially leading to pain and discomfort, especially during physical activity. Over time, unchecked progression of the disease may cause the complete blockage of the artery, leading to serious complications such as tissue death and potential amputation of the affected limb. It’s important to note that atherosclerosis is a systemic disease, often affecting other arteries throughout the body, not only in the extremities. This means individuals with this condition may also have a higher risk of heart attacks and strokes.
