Carotid endarterectomy Often considered one of the safest ways to treat symptomatic carotid stenosis, carotid endarterectomy is a procedure by which a surgeon gently removes atherosclerotic plaque. Blood flow hopefully then returns to normal, increasing oxygen concentration to normal amounts in<unk>  areas of the brain. There is the potential for complications, including disturbing portions of the plaque leading to a<unk>  or heart attack during or after surgery. Small risks of bleeding and infection exist as well. Percutaneous treatments of carotid stenosis In this type of procedure, a narrowed blood vessel is expanded via angioplasty or stenting. A thin angiography catheter is inserted in a large groin blood vessel and advanced to the stenosis. Percutaneous treatment is less invasive than endarterectomy, usually requiring only local anesthesia. Endarterectomy is still considered safer though, as percutaneous treatments can lead to accidental dislodging of plaque or even arterial rupturing. Carotid angioplasty During carotid angioplasty, an angiography cather with a small deflated balloon attached on the tip is advanced to a carotid stenosis. The ballon is then inflated slowly, forcing the narrowed portion of the vessel to expand. Carotid stenting Carotid stenting follows a similar procedure. Rather than using a balloon, a stent (metal mesh-like tube) is placed over the atherosclerotic plaque in the hopes of stabilizing it and allowing for increased blood flow to<unk>  portions of the brain.
