Renal angioplasty is a procedure that aims at widening obstructed renal arteries to restore the flow of blood to the kidneys. The procedure is usually recommended to patients with chronic renal artery stenosis, which is usually triggered by atherosclerosis or fibrous artery disease.
Major indications of renal artery angioplasty include:
- Renovascular hypertension with or without a family history
- Sudden onset of renovascular hypertension
- Renovascular hypertension that is not responding well to drugs and medication
- Renal failure or decline in renal function
- Congestive heart failure
- Unstable angina
- The procedure involves the use of a catheter which is inserted by making an incision near the groin
- The catheter is then guided towards the affected artery using detailed imaging guidance
- A guidewire with a balloon on one of its ends is used to detect the blockage
- The balloon is inflated to open the narrowed artery.
- A stent may be used during the procedure to prevent the artery from narrowing again.
- Once the blockage has been cleared, the catheter is removed along with the guidewire and balloon, and the incision is closed.
