2. Renal artery stenosis - Wikipedia

   en.wikipedia.org/wiki/Renal_artery_stenosis

   Renal artery stenosis (RAS) is the narrowing of one or both of the renal arteries, most often caused by atherosclerosis or fibromuscular dysplasia. This narrowing of the renal artery can impede blood flow to the target kidney , resulting in renovascular hypertension – a secondary type of high blood pressure .

   An atheroma, or atheromatous plaque, is an abnormal accumulation of material in the inner layer of an arterial wall. [ 1 ] [ 2 ] The material consists of mostly macrophage cells , [ 3 ] [ 4 ] or debris, containing lipids , calcium and a variable amount of fibrous connective tissue .

4. Atherosclerosis - Wikipedia

   As long as the artery enlarges sufficiently to compensate for the extra thickness of the atheroma, then no narrowing ("stenosis") of the opening ("lumen") occurs. The artery expands with an egg-shaped cross-section, still with a circular opening. If the enlargement is beyond proportion to the atheroma thickness, then an aneurysm is created. [71]

   Hypertensive nephropathy refers to kidney failure that can be attributed to a history of hypertension [7] It is a chronic condition and it is a serious risk factor for the development of end-stage kidney disease (ESKD). However, despite the well-known association between hypertension and chronic kidney disease, the underlying mechanism remains ...

   These changes are most prominent in the kidney and can lead to ischemia and acute kidney failure. In the brain, a small cavity called a lacune is an ischemic cavity that can arise due to brain necrosis, due to arteriolosclerosis. [15] [16] Cause.
