Which statement correctly describes the radial artery as a CABG graft?

• A. Located in the arm and can be used as a CABG conduit.
• B. Harvested from the leg.
• C. Dissected at the distal end & anastomosed to the coronary artery distal to occlusion.
• D. Proximally anastomosed to the ascending aorta.

Answer: (A)

Radial artery grafts come from the forearm and can be used as CABG conduits. This artery is a muscular, medium-caliber arterial conduit that surgeons harvest to bypass blocked coronary arteries, taking care to confirm adequate hand circulation after harvest (often with an Allen test). The core fact is its origin in the arm and its role as an arterial graft for bypass surgery, which is why this statement is correct. It isn’t sourced from the leg—that would describe saphenous vein or leg arteries. While a radial graft is commonly attached proximally to the ascending aorta and distally to a coronary artery beyond the occlusion, the essential point remains its arm location and its use as a CABG conduit.
