Why the study?
Randomized clinical trials comparing the radial artery with other CABG grafts were underpowered, leaving uncertainty regarding the best second-best target vessel for CABG.
Does the use of the radial artery as a second target conduit improve clinical outcomes and patency rates compared to saphenous vein grafts in patients undergoing CABG?
Population
Patients who received arterial conduit and saphenous vein grafts for CABG
Comparison
Radial artery vs other grafts including saphenous vein grafts
Design
Literature review of randomized controlled trials, propensity-matched series, and meta-analyses

Supports radial artery preference as second CABG conduit; leaves open randomized confirmation before practice change.
Does the use of the radial artery as a second target conduit improve clinical outcomes and patency rates compared to saphenous vein grafts in patients undergoing CABG?
The radial artery is the preferred second conduit of choice for CABG after the left internal thoracic artery, demonstrating superior patency and outcomes compared to saphenous vein grafts.
