Carotid Angioplasty Stenting (CAS)
Carotid angioplasty is a technique that involves opening a narrow (atherosclerotic) carotid artery from inside the blood vessel using a balloon and a stent (hollow tube of wire-like mesh). A catheter is introduced into the femoral artery in the groin area through a small (quarter inch) skin incision. The catheter is guided up to the carotid artery in the neck, and a balloon is then passed through the catheter to the area of blockage. The balloon is inflated to open up the blockage. After the blockage has been opened, a stent is placed across the area of narrowing to keep the artery wide open. The procedure is performed while the patient is awake and most patients will go home the next day.
