Key result
Free arterial grafts provide equivalent basal flow to saphenous vein grafts, determined by native coronary vessels.
Why the study?
Does free arterial graft flow capacity differ from saphenous vein graft flow capacity in patients undergoing coronary bypass surgery?
Observational (n=20)
Does free arterial graft flow capacity differ from saphenous vein graft flow capacity in patients undergoing coronary bypass surgery?
Absolute Event Rate: 102.5% vs 102%
Free arterial grafts provide equivalent basal flow to saphenous vein grafts, demonstrating adequate flow reserve for coronary bypass surgery.

Supports equivalent basal flow for free arterial grafts in CABG; leaves open long-term reserve and outcomes versus vein grafts in RCTs.
Hall et al. (2001) conducted an observational in Coronary Bypass Surgery (n=20). Free arterial grafts vs. Saphenous vein grafts was evaluated on Graft flow capacity. Basal flow through free arterial grafts (102.5 ± 28.5 ml/min) was equivalent to saphenous vein grafts (102 ± 28 ml/min) and primarily determined by native coronary vessels.
