A pathological state of the aorta associated with the tertiary stage of syphilis infection.<unk>  begins as inflammation of the adventia, including the vessels that supply the aorta itself with blood, the vasa vasorum. As the disease progression worsens, the vasa vasorum demonstrate hyperplastic thickening of their walls that restricts blood flow and causes ischemia of the outer 2/3's of the aortic wall.  Starved for oxygen and nutrients, elastic fibers become patchy and smooth muscle cells necrose. The wall weakens and scars. If the disease progresses,<unk>  may lead to an aortic aneurysm.
