Renal Artery Disease

Renal artery disease refers to narrowing of the arteries that supply the kidneys. Most often, it’s caused by atherosclerosis, when the blood vessels become narrowed or clogged by fatty or cholesterol deposits called plaque. It also can be caused by fibromuscular dysplasia, when the arteries are narrowed by abnormal tissue growth.

The job of the kidneys is to regulate body fluid, blood pressure and blood chemistry – removing waste from the bloodstream. When their function is impaired by blood flow problems, they can cause high blood pressure, called renal hypertension. It can lead to heart attack, stroke or kidney failure. It also can cause renal insufficiency, which means the kidneys aren’t functioning at full capacity.

Renal artery disease symptoms

Some signs of renal artery disease are:

  • High blood pressure that suddenly worsens
  • High blood pressure during youth
  • High blood pressure paired with kidney problems
  • High blood pressure paired with other diseases of atherosclerosis

Renal artery disease risks

The risks for renal artery disease are the same as those for other diseases related to atherosclerosis. African Americans and people over 50 have increased risk of CLI. You can't control your age or race, but you can control these risk factors:
