Why the study?
Does the use of radial artery grafts improve patency rates compared to saphenous vein grafts in patients undergoing coronary bypass surgery?
Does the use of radial artery grafts improve patency rates compared to saphenous vein grafts in patients undergoing coronary bypass surgery?
While radial artery grafts have better mid- and long-term patency than saphenous vein grafts, the clinical benefits remain unclear due to limitations in existing evidence.
Feature Editor Note—Few topics in cardiac surgery have been investigated more extensively that the use of multiple arterial grafts for coronary bypass surgery. After more than 4 decades of research, we have solid evidence than the patency rate of the radial artery is better than the patency rate of the saphenous vein at mid- and long-term follow-up. The evidence for the other arterial conduits is less robust. The clinical consequences of the improved patency are still unclear, due to the high level of treatment allocation bias in observational studies and the inconclusive results of the limited randomized evidence.
