Carotid Artery Endarterectomy
by Amy Scholten, MPH

Description of the Procedure
An incision will be made in the skin along the side of the neck. The incision will run from behind the ear to above the breastbone. Clamps will be placed above and below the plaque on the carotid artery. Sometimes, a temporary bypass tube is used. The tube will maintain blood flow around the area that is being worked on.
The artery will be opened and cleaned of plaque. The artery will then be sewn back together. The clamps, and bypass tube, if used, will then be removed. A part of the carotid artery may need to be removed. In this case, an artificial graft or a piece of vein will be sewn in to replace it. The neck incision will be closed with stitches. A bandage will be placed over the site.
