Angioplasty and Stenting

Balloon angioplasty for renal artery stenosis

Your doctor inserts a catheter through a small incision in the groin and guides it through to your renal artery. The catheter has a tiny balloon that is inflated at the site of the plaque to flatten it against the walls of the artery. Your doctor may insert a stent (tiny metal-mesh) in the artery to hold the blood vessel open and prevent it from collapsing.
