Practice questions on Nephrosclerosis
A 57-year-old man has had blood pressure measurements in the range of 160/95 to 180/110 mm Hg for many years. He has taken no medications. A renal scan reveals kidneys of normal size for age. These findings with benign nephrosclerosis are most likely to occur with which of the following vascular changes?
- Hyaline arteriolosclerosis
- Monckeberg's medial calcific sclerosis
- Complex calcified atherosclerosis
- Arterial mural thrombosis
- Hyperplastic arteriolosclerosis
Answer: A. Hyaline arteriolosclerosis is a feature of long-standing hypertension and is part of benign nephrosclerosis which may go on for many years with no complications. The small arterioles are thickened with pink (hyaline) proteinaceous deposits. ---
