The surgical procedure that uses a blood vessel from another part of the body to channel blood around an occluded coronary artery is the coronary Artery Bypass Graft. This is a procedure that restores blood flow to the heart muscle by diverting the flow of blood around a section of a blocked artery in the heart. Specialists use this procedure to treat people who have severe coronary heart disease, a disease in which a waxy substance called plaque builds up inside the coronary arteries.
