Atherosclerosis is hardening of a blood vessel from a buildup of plaque. Plaque is made of fatty deposits, cholesterol, and calcium. It builds on the inside lining of arteries. This causes the artery to narrow and harden. As plaque builds up, it can slow and even stop blood flow.
Endarterectomy is a surgery to remove this build-up and improve blood flow. Surgery is most often performed on:

Description of the Procedure TOP
Incisions will be made over the diseased part of the artery. The location will depend on the artery that is being unblocked.
In the abdomen and legs, the artery above the obstruction will be clamped during the repair. The lower half of the body can go without blood supply during the time it takes to do the surgery. If surgery is done on the neck, the blood around the surgical site may first be rerouted. This will keep blood going to the brain.
The inside of the artery will be cleaned out. Care will be taken not to have small fragments of the deposits break off and flow downstream, causing stroke or arterial occlusion. After the artery is cleaned out, the artery and the skin will be closed with sutures or staples.
