Dear Cindy,
The use of the radial artery from the arm as a bypass graft is a relatively new but accepted technique. It is known that the mammary artery graft does much better than vein bypass. The theory is that the radial artery grafts will also do better over the long run. There are no long-term outcome studies yet. The potential risk is that the graft will close early and the potential advantage is that it will stay open much longer.
