Atherosclerosis was traditionally thought to be a chronic, slowly progressive, degenerative disease; however, it has been established that the disorder is marked by periods of activity and quiescence. The condition has a common pathogenesis and can affect multiple circulatory organs. Despite being a systemic disease, atherosclerosis manifests focally, though the reasons why and how affected organ systems differ from patient to patient is still unclear.
Because aortic aneurysms share many of the same risk factors as obstructive atherosclerosis and always cause significant atherosclerotic damage to the aortic wall, they were historically viewed as a form of atherosclerosis. However, this classification has been challenged as newer data indicate that aneurysms arise through other pathogenic mechanisms and not those responsible for athero-occlusive disease.
