Renal Artery Stenotic Disease

The kidney is a bean-shaped organ that lies within the abdomen. They serve many functions including filtering impurities from the blood to produce urine, regulation of plasma electrolytes and acid-base balance, regulation of blood pressure and production of some hormones. The kidneys receive their blood supply usually by a single renal artery, that branches from the abdominal aorta.

Stenoses of the arteries to the kidneys may be caused by the following:

  • Atherosclerosis (most common)
  • Fibromuscular Disease
  • Inflammatory Artertis

Stenoses of the arteries to the kidneys may be asymptomatic, or may cause the following problems:

  • High blood pressure
  • Sudden pulmonary oedema
  • Chronic renal failure

Stenoses of the arteries to the kidneys can be identified and monitored with a non-invasive duplex ultrasound. Other investigations that can be performed include CT angiography, MR angiography and catheter angiography.

Stenoses of the renal arteries can be treated by a number of means. These include:

  • medications, such as antihypertensive medication, cholesterol lowering medication or antiplatelet medication.
  • endovascular techniques, such as angioplasty and stenting
  • Surgery, such as endarterectomy or bypass

After review of your history, physical examination and investigations we will formulate an appropriate treatment plan for you.
