Renal artery stenosis. Renal artery stenosis (RAS) is a blockage of an artery to the kidneys. It may cause kidney failure and hypertension (high blood pressure). Smokers have a greater risk of developing RAS.

Renal artery stenosis. This is a narrowing or blockage of the renal artery before it enters your kidney. In older adults, blockages often result when fatty deposits accumulate under the lining of the artery walls (atherosclerosis).

renal artery stenosis: Narrowing of the lining of the main artery that supplies the kidney.
renovascular disease: Progressive condition that causes narrowing or blockage of the renal arteries or veins.

Renal artery stenosis is a narrowing or blockage of the artery that supplies blood to the kidneys.
The most common cause of renal artery stenosis is hardening of the arteries (atherosclerosis) from high cholesterol.

Renal artery stenosis triggers the release of these hormones, which then becomes a cause for hypertension (high blood pressure).

This is known as transplant renal artery stenosis. This can limit blood flow to the kidney. It also makes it difficult to keep blood pressure under control.

One important secondary cause of hypertension, which has good results from treatment, is renal artery stenosis (RAS). Stenosis means narrowing, or partial blockage of the blood vessel that carries blood to the kidney.

The patient has severe high blood pressure (hypertension) caused by renal artery stenosis. In this condition, a diseased artery results in damage to one kidney.
