- Atherosclerosis—Fatty plaque builds up in the arteries and blocks blood flow to the kidneys. This occurs mainly in men over 50 years old.
- Fibromuscular dysplasia—An inherited disorder where muscle and fibrous tissue of the renal artery wall thicken and harden into rings that block blood flow to the kidneys. This occurs mainly in young women in their 30s.
- Very high and difficult to control blood pressure
- Episodes of heart failure
- Rapid kidney failure
- Newly discovered high blood pressure in men over 50 years old or young women in their 30s
- Calcium channel blockers
- ACE inhibitors (except in those with both renal arteries blocked)
- Angiotensin receptor blockers
Interventions to Correct Renovascular Hypertension
- Revascularization—A new path for blood flow to the kidneys is created by connecting a vein or tube above and below the blocked area.
- Angioplasty—A catheter with a balloon at its tip is inserted into the blocked artery. The balloon is quickly inflated and deflated to stretch open the artery to allow blood flow. The doctor may insert a small metal mesh tube (stent) into the artery to help it stay open.
- Endarterectomy—Surgery to remove the inner-lining of the renal artery containing the plaque.
- If you smoke, talk to your doctor about how you can successfully quit.
- Maintain a healthy weight.
- Follow treatment plans if you have high cholesterol or blood pressure.
- Exercise regularly.
- Eat a low-fat, low-protein, low-sodium, high-fiber diet.
