Arteriosclerosis obliterans

Arteriosclerosis obliterans is an occlusive arterial disease most prominently affecting the abdominal aorta and the small- and medium-sized arteries of the lower extremities, which may lead to absent dorsalis pedis, posterior tibial, and/or popliteal artery pulses.

It is characterized by fibrosis of the tunica intima and calcification of the tunica media.
