Full Answer

Carotid artery surgery is the removal of plaque from the carotid arteries to enhance blood supply to the brain in patients who experience lack of proper blood supply to the brain, explains Healthgrades. The procedure treats carotid artery stenosis and prevents occurrence of stroke. Types of Carotid artery surgery include carotid endarterectomy, and carotid artery angioplasty and stenting. Carotid endarterectomy is a type of carotid artery surgery in which a surgeon opens the neck carotid arteries and removes the inner plaqued lining of the arteries to enhance blood flow to the brain. In carotid artery angiosplasty and stenting, a surgeon widens the carotid artery by placing in a catheter through the groin or elbow blood vessels, and puts a stent in the artery to keep the artery open, enhancing sufficient blood supply to the brain.

To determine the amount of plaque in the carotid artery, a surgeon may perform carotid angiography or carotid ultrasound before the surgery, states Healthgrades. While carotid angiography is an imaging test of the carotid arteries, carotid ultrasound involves screening the carotid arteries to determine their ability to pass the blood.
