Final answer:
A reverse vein graft is a surgical procedure that uses a section of a vein, usually from the leg, to bypass a blocked artery. This procedure is commonly used in coronary artery bypass surgery to restore blood flow to the heart.
Step-by-step explanation:
A reverse vein graft is a surgical procedure performed to bypass a blocked artery by using a section of a vein, usually from the leg, as a replacement or graft. The vein is reversed, meaning that the direction of blood flow is reversed, so that the valves in the vein do not obstruct blood flow in the graft. This procedure is commonly used in coronary artery bypass surgery to restore blood flow to the heart.
