Cerebral atherosclerosis is a type of atherosclerosis where build-up of plaque in the blood vessels of the brain occurs. Some of the main components of the plaques are connective tissue, extracellular matrix, including collagen, proteoglycans, fibronectin, and elastic fibers; crystalline cholesterol, cholesteryl esters, and phospholipids; cells such as monocyte derived macrophages, T ...
Secondary causes of nephrotic syndrome have the same histologic patterns as the primary causes, though they may exhibit some differences suggesting a secondary cause, such as inclusion bodies. [24] They are usually described by the underlying cause, such as: [citation needed] Diabetic nephropathy: is a complication that occurs in some diabetics ...
Benign nephrosclerosis alone hardly ever causes severe damage to the kidney, except in susceptible populations, such as African Americans, where it may lead to uremia and death. However, all persons with this disease usually show some functional impairment, such as loss of concentration or a variably diminished GFR.
"Hypertensive" refers to high blood pressure and "nephropathy" means damage to the kidney; hence this condition is where chronic high blood pressure causes damages to kidney tissue; this includes the small blood vessels, glomeruli, kidney tubules and interstitial tissues. The tissue hardens and thickens which is known as nephrosclerosis. [2]
Lesions reflect leakage of plasma components across vascular endothelium and excessive extracellular matrix production by smooth muscle cells, usually secondary to hypertension. [11] Hyaline arteriolosclerosis is a major morphologic characteristic of benign nephrosclerosis, in which the arteriolar narrowing causes diffuse impairment of renal ...
Similar to other causes of nephrotic syndrome (e.g., focal segmental glomerulosclerosis or minimal change disease), membranous nephropathy is known to predispose affected individuals to develop blood clots such as pulmonary emboli. Membranous nephropathy in particular is known to increase this risk more than other causes of nephrotic syndrome ...
Many causes of secondary FSGS contribute to podocyte injury through hyperfiltration, which is a scenario of excess filtration by renal glomeruli. [24] Hyperfiltration can be caused by obesity, diabetes or loss of the contralateral kidney, among other causes. [24] Secondary FSGS can also be caused by toxins, including anabolic steroids and heroin.
Atrial fibrillation causes blood clots to form within the heart, which may travel to the arteries within the brain and cause an embolism. The embolism prevents blood flow to the brain, which leads to a stroke. [26] An aneurysm is an abnormal bulging of small sections of arteries, which increases the risk of artery rupture.
