Peripheral arterial disease (PAD) is a condition that arises from stenosis or occlusion in any part of the arteries that perfuse the lower extremities from the abdominal aorta-iliac arteries to the feet. This can lead to intermittent claudication, lower limb ischemia, gangrene of the toes, amputation, impaired physical ability, and decreased quality of life. While multiple diseases can cause arterial occlusion, the majority of cases are due to atherosclerosis. Therefore, in many guidelines, the term PAD is used synonymously with occlusive atherosclerotic disease of the lower extremities (Gerhard-Herman et al. 2017; Aboyans et al. 2018).
