Nephrologic Disease

Renal Artery Stenosis

HIGH SEVERITY

Narrowing of one or both renal arteries reducing blood flow to the kidneys. Causes hypertension that can be difficult to control and can lead to kidney damage. Usually caused by atherosclerosis (older patients) or fibromuscular dysplasia (younger women).

Global Affected

7.0M

Countries

89

Symptoms

Hypertension (difficult to control)
Sudden onset hypertension
Decreased kidney function
Fluid retention
Swelling
Often asymptomatic
Abdominal bruit

Treatment Options

Blood pressure medications
ACE inhibitors/ARBs
Statins
Antiplatelet agents
Angioplasty and stenting
Surgical revascularization
Risk factor modification

Risk Factors

1Atherosclerosis
2Age >50
3Fibromuscular dysplasia
4Young women (FMD)
5Smoking
6Diabetes
7High cholesterol
8Family history
9Peripheral artery disease

Diagnostic Methods

  • 1Doppler ultrasound
  • 2CT angiography
  • 3MR angiography
  • 4Renal arteriography
  • 5Captopril renography
  • 6Plasma renin activity

Prognosis

Variable. Medical management effective for many. Revascularization benefits selected patients. Can lead to end-stage kidney disease without treatment. Cardiovascular risk high.

Prevention

  • Blood pressure control
  • Cholesterol management
  • Smoking cessation
  • Diabetes control
  • Regular exercise
  • Healthy diet
  • Aspirin therapy (selected)

Research Status

Medical management (ACE inhibitors, statins, antiplatelets) first-line. Angioplasty with stenting for certain cases. Surgery rarely needed. Optimal medical therapy often equivalent to revascularization in atherosclerotic cases.
