Which graft is harvested from the leg?

• A. Saphenous vein graft
• B. Internal mammary artery
• C. Radial artery
• D. Pulmonary artery

Answer: (A)

The saphenous vein graft is harvested from the leg. In CABG, surgeons use conduits to bypass blocked coronary arteries, and the great saphenous vein running along the leg is a common source because it provides a long, usable conduit that can be fashioned to connect the aorta to the coronary arteries. It is typically removed via an open or endoscopic harvest, then prepared (often reversed) to function under arterial pressure. The other options originate from different sites—internal mammary artery from the chest wall, radial artery from the forearm, and the pulmonary artery is not used as a standard graft—in contrast to the leg’s saphenous vein.
