History and Physical Examination in Diagnosis of Peripheral Artery Disease

Peripheral artery disease (PAD) may be silent or present with an assortment of symptoms and signs suggesting peripheral artery ischemia. Peripheral vascular disease includes PAD and disorders of the peripheral venous system and lymphatic system. Generally, PAD is synonymous with arteries of the limbs and pelvis, but it can be expanded to include the renal arteries, carotid arteries, mesenteric arteries, and the aorta. It is imperative to recognize and treat PAD early, as appropriate management of PAD can help avoid devastating complications such as limb amputation and death.
