Carotid angioplasty (kuh-ROT-id AN-je-oh-plas-te) is a procedure that opens clogged arteries to prevent or treat stroke. The carotid arteries are located on each side of your neck and are the main arteries supplying blood to your brain. The procedure involves temporarily inserting and inflating a tiny balloon where your carotid artery is clogged to widen the artery.
Carotid angioplasty is often combined with the placement of a small metal coil called a stent in the clogged artery. The stent helps prop the artery open and decreases the chance of it narrowing again. Carotid angioplasty and stenting may be used when traditional carotid surgery isn't feasible or is too risky.
