Causes

Atherosclerosis is the predominant cause of renal artery stenosis in the majority of patients, usually those with a sudden onset of hypertension at age 50 or older. Fibromuscular dysplasia is the predominant cause in young patients, usually females under 40 years of age. A variety of other causes exist. These include:

• Arteritis
• renal artery aneurysm
• Extrinsic compression (eg. neoplasms)
• Neurofibromatosis
• Fibrous bands.
