There has been much confusion in the use of the terms arteriosclerosis and atherosclerosis. Arteriosclerosis is a diffuse lesion, which often affects long segments of the arterial tree in which there is usually a combination of hypertrophic and fibrous changes in the entire thickness of all layers of the arterial wall. The  media and  adventitia are commonly affected by this disease process. Atherosclerosis is the term used for atheroma of arteries. It is typically patchy with a focal lesion of the  intima and media with degeneration and formation of plaques of atheroma, which protrude into the lumen of the vessel obstructing the flow of blood ( Atherosclerosis/Atheroma).

Hypertensive Arteriosclerosis

Prolonged hypertension causes the walls of the affected arteries to become firmer and thicker, and the lumen is often wider than normal. Arteries appear to be generally enlarged and become somewhat tortuous. These changes can be seen especially in the retinal arteries...
