How is a renal artery angioplasty with a stent done?

Renal Angioplasty: Angioplasty is balloon revascularization. Usual approach is 2mm incision in the femoral artery at groin, sheath inserted, followed by the cannulation of the artery with a catheter. Dye is injected to locate area in need of angioplasty. Balloon over a wire via the catheter & when in place is inflated to an appropriate pressure. The balloon is removed and then stent deployed and inflated at stenosis.

Renal angio: Access through the femoral artery in the groin and a catheter is placed into the renal arteries. A wire is then used to cross the stenosis follwed by balloon angioplasty then stent placement.
