Carotid Endarterectomy (CEA) is an elective surgical procedure that removes plaque from the lumen of the carotid artery. After anesthesia, the surgeon clamps the carotid artery proximal and distal to the stenosis temporarily. The surgeon may place a shunt proximal to the clamp to reroute blood to the brain. Next, an incision is made over the area of blockage. The plaque is scraped out and separated from the inner lining of the artery. After it is removed, the artery is sutured together, the clamps are removed, and any bleeding is stopped. Finally, the skin incision is closed.
The arch of the aorta gives off three branches: the innominate, the left common carotid, and the left subclavian. The innominate artery, also known as the brachiocephalic artery, gives rise to the right subclavian artery and the right common carotid artery. The common carotid arteries bilaterally split into internal and external carotid arteries. The right and left...
