Saphenous Vein Graft
When undergoing a coronary heart bypass surgery, a graft of a healthy vessel is used for rerouting the blood flow around the blocked vessel on the heart. A portion of the great saphenous vein is commonly used for this purpose and is preferred over an artificial vessel because it has a longer patency. The vein graft is taken from the patient's leg in the knee region and used to connect coronary arteries and restore blood flow to the heart. It is a life saving procedure.
