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.
Renovascular hypertension is caused by diminished blood flow to one or both kidneys. As a result, the kidneys release hormones that cause the body to retain sodium and water, leading to elevated blood pressure. There are many causes of decreased blood flow to the kidneys. These include: [5] Atherosclerotic renal artery stenosis; Fibromuscular ...
