Similar to cholesterol deposition witnessed in coronary arteries, In High blood patients, it has been seen that cholesterol deposition occurs in the renal arteries aswell. These depositions lead to the stenosis of the renal artery. If not treated in time they can lead to high blood pressureand also severe kidney complication; even failure of the Kidney. The procedure to treat this renal artery stenosis is called Renal Artery Angioplasty.
Renal Artery Angiogplasty is performed using a catheter technique in a cardiac catlab. In this procedure the catheter is passed through the femoral artery in the groin area upto the renal artery. The catheter is a fine tube though which angioplasty wires can be passed to reach the region of treatment. Through the catheter a fine wire/guide-wire is passed across the region of obstruction. Over the guide wire a balloon catheter is passed to the region of obstruction. The balloon is kept in-between the narrowed area and is inflated. As the balloon is inflated with high pressure it widens the narrowing. Now the balloon is deflated and a another catheter which has a balloon loaded with stent is introduced at the widened area. This stent, is now installed by inflating the high-pressure balloon. Once the stent is fixed to the wall of the artery we deflate the balloon and remove it. This is also called renal artery stenting.
Post renal angioplasty are there any complications?
There are negligible to no complication post-surgery.
How long does the procedure last?
The procedure takes about 30 minutes.
How long is the hospital stay?
The patient has to stay in the hospital for 1 – 2 days.
