Why the study?
Does radial artery graft improve graft patency compared to saphenous vein graft in patients undergoing coronary bypass procedures?
Does radial artery graft improve graft patency compared to saphenous vein graft in patients undergoing coronary bypass procedures?
Radial artery grafts showed a high rate of early postoperative occlusion compared to saphenous vein grafts, leading to the authors' recommendation against their use for coronary bypass.
No takes yet. Share an insight, caveat, or question.
Radial artery grafting was associated with higher early occlusion; leaves open optimal conduit selection pending randomized data.
Fisk et al. (1976) studied this question.
