An operation to clean out an artery and restore normal blood flow through the artery.

An endarterectomy is basically a "Rotorooter" procedure. It removes diseased material from the inside of an artery, and also removes any occluding atheromatous deposits, with the purpose of leaving a smooth lining within the vessel, so the blood can flow normally.

Endarterectomy (a surgical procedure designed to clean out material occluding an artery) done on the carotid artery (a major artery in the neck that supplies blood to the brain) to restore normal blood flow through it to the brain and to prevent a stroke.
