Atherosclerosis is a diffuse multicentric disease in the arterial tree, affecting target organs (heart, aorta, lower extremities, carotid arteries etc.). Mostly located in arterial bifurcations (Iliac and carotid artery bifurcations) or in constant repetitive arterial trauma (Adductors tendon, Hunter's canal). The invasive treatment (endovascular, surgery) is preserved for patients with critical arterial stenosis or occlusion in symptomatic patients. Exceptions are the carotid arteries: the majority of patients with a severe internal carotid artery stenosis are asymptomatic patients, which are treated for the prevention embolic events (TIA's or CVA's).
