Aortoiliac occlusive disease, commonly referred to as Leriche syndrome, represents a significant vascular condition characterized by the obstruction of blood flow in the aortoiliac region. This syndrome arises from atherosclerosis, a disease process where fatty deposits accumulate on the arterial walls, leading to narrowing or occlusion of the arteries. Specifically, Leriche syndrome affects the bifurcation of the abdominal aorta into the common iliac arteries, which are critical in supplying oxygenated blood to the lower extremities. As the disease progresses, patients may experience a variety of symptoms related to insufficient blood flow, including claudication, which is defined as muscle pain or cramping in the legs triggered by physical activity and relieved by rest.
