Radial Artery Versus Saphenous Vein Grafts in Coronary Artery Bypass Surgery: A Grade- Assessed Meta-Analysis of Randomized Controlled Trials
This meta-analysis of randomized controlled trials indicates that while radial artery grafts reduce complete anatomical occlusion compared to saphenous vein grafts, their overall superiority is limited by a higher risk of functional occlusion due to competitive flow, suggesting that conduit selection should be individualized based on patient and vessel characteristics.
