Bacterial colonies in the vessel wall
Lipid deposition and smooth muscle cell hyperplasia
Answer 😀 Lipid deposition and smooth muscle cell hyperplasia
Atherosclerosis is a disease of large and medium- sized elastic and muscular arteries that results in the progressive accumulation within the intima of inflammatory cells, hyperplastic smooth muscle cells, lipids, and connective tissue.
The resulting characteristic lesion, the lipid plaque (atheroma), contains pools of extracellular lipid and numerous lipid-laden macrophages (foam cells).
It is not an acute inflammatory or infectious process. Obliterative endarteritis is a syphilitic lesion.
