Carotid endarterectomy (CEA) is a treatment for carotid artery disease. The carotid arteries are the main blood vessels that carry oxygen and blood to the brain. In carotid artery disease, these arteries become narrowed. This reduces blood flow to the brain and could cause a stroke. For a carotid endarterectomy, your doctor will surgically remove plaque that builds up inside the carotid artery. He or she will make an incision on the side of the neck over the affected carotid artery. The artery is opened and the plaque removed.
