Atherosclerosis of the aorta
•Abdominal aorta with the bifurcation of iliaca arteries.
•The intima is rough and uneven because of the presence of yellowish (lipid) spots and elevated dense whitish fibrous plaques , which constrict and deform the lumen.
•Hard-set wall ‘creaks’ when cutting it to wide open because of degenerative calcification, and the surface is ulcerated
•Dark uneven brown-red mass over the bifurcation presents mural thrombosis, which occludes iliac arteries distally
•Finally a gangrene of lower limbs can develop
