Why the study?
Does the use of sequential vein grafts affect total and distal blood flow compared to single grafts in patients undergoing CABG?
Does the use of sequential vein grafts affect total and distal blood flow compared to single grafts in patients undergoing CABG?
Sequential vein grafts provide similar total blood flow to single grafts, with evidence of significant collateral supply between adjacent coronary beds.
No takes yet. Share an insight, caveat, or question.
Sequential grafts may preserve total flow via collaterals in CABG; leaves open whether distal flow reduction affects outcomes.
McNamara et al. (1979) studied this question.
