除动脉粥样硬化之外,还有其它两种形式的动脉硬化（动脉变硬）∶细动脉硬化症和动脉中层钙化。肾脏可见典型的细动脉硬化。经过PAS染色，可见连接右下方肾小球的细动脉已明显变厚，它就是被称为玻璃样变细动脉硬化的一种形态。玻璃样变细动脉硬化可见于老年人，但是在有糖尿病和/或有高血压的病人中有着更严重的病变。
There are two other forms of arteriosclerosis (hardening of the arteries) in addition to atherosclerosis: arteriolosclerosis and medial calcific sclerosis. Arteriolosclerosis is typically seen in the kidneys. One form, called hyaline arteriolosclerosis, is demonstrated by the markedly thickened arteriole to the lower right of this glomerulus with PAS stain. Hyaline arteriolosclerosis is seen in the elderly, but more advanced lesions are seen in persons with diabetes mellitus and/or with hypertension.
