Renal Artery Stenosis


What is renal artery stenosis?

Hypertension is a serious health problem in India and its prevalence is gradually increasing. Among hypertensives an estimated 3 to 8 % have hypertension caused by arterial blockage or narrowing of the renal artery, i.e., Renal artery stenosis causing decreased blood flow to the kidney.


This decreased blood flow to the kidney results in systemic (body-wide) constriction of the blood vessels causing blood pressure to rise.


Renal Hypertension puts stress and increases pressure on the kidney causing chronic renal disease, or end-stage renal disease.


End-stage renal disease requires a person to receive dialysis or be placed on a list for a kidney transplant.


Complications If Untreated

  • Retinopathy, i.e., damage to the eyes from high blood pressure
  • Renal insufficiency or failure
  • Myocardial infarction, i.e., heart attack
  • Premature death
  • Stroke
  • Renal insufficiency or failure
  • Heart disease with hypertension


Renal artery stenosis can be diagnosed using:

  • Colour Doppler
  • MR angiogram
  • CT angiogram.


Angioplasty and/or stenting can be performedto improve blood flow to the kidney.

It is a relatively low risk procedure and can greatly improve blood pressure and prevent further damage to the kidney.
