Correct Answer: Hyaline aeriolosclerosis
Description: Hyaline aeriolosclerosis: It is seen in the aerioles in patients with benign hypeension. * Microscopy: It shows thickening of the wall due to homogeneous, pink hyaline material and narrowing of the lumen (Fig. 9.7A). * Mechanism: Chronic hemodynamic stress produced by hypeension - produces leakage of protein into the vessel wall - increased synthesis ECM by smooth muscle cell - hyalinization of the wall of aeriole. * Consequence: The aeriolar narrowing - impaired blood supply to kidney - produces ischemia and glomerular scarring. The kidney changes in benign hypeension are called benign nephrosclerosis. Manual of pathology of ramadas nayak Edition 1 Pageno.287
