Renal Artery Disease
Balloon Angioplasty: a long thin tube (catheter) with a tiny balloon attached to the tip is inserted through a small incision (cut) made in your groin. The catheter is guided through the arteries to the site of the blockage where the balloon is inflated to clear the blockage and, in some cases, a metal tube (stent) is inserted into the artery to keep it open.
Endarterectomy: an incision is made over the artery, the artery opened and the fatty material (plaque) removed.
Bypass Surgery: a piece of a vein from another part of the body or a tube made of synthetic material (graft) is used to join the artery above and below the narrowed or blocked section. This creates a detour and a new path for the blood to flow around the blocked segment.
