During bypass surgery, a graft harvested from the patient's own vein is called what?

• A. Allograft
• B. Synthetic graft
• C. Autologous graft
• D. Xenograft

Answer: (C)

Autologous graft refers to tissue taken from the same person. When a bypass graft uses a vein harvested from the patient’s own body, such as the saphenous vein, it is autologous because the tissue origin is the individual themself, which reduces immune rejection and compatibility issues. Other terms describe grafts from different sources: allograft is from another human donor, xenograft from another species, and synthetic graft is man-made material. So the graft described is autologous.
