Preparation of human saphenous vein for coronary artery bypass grafting impairs its capacity to produce prostacyclin
Key result
Routine surgical preparation of human saphenous vein for coronary bypass grafting significantly reduced stimulated prostacyclin production from 16.9 to 7.1 pg/min per mg wet weight.
Why the study?
Does routine surgical preparation of human saphenous vein for CABG impair prostacyclin production compared to freshly isolated vein?
Population
Human saphenous vein samples (n=27)
Comparison

Implication
May increase early graft occlusion risk via endothelial injury; leaves open whether refined harvesting techniques improve patency.
Structured PICO
Does routine surgical preparation of human saphenous vein for CABG impair prostacyclin production compared to freshly isolated vein?
P
Population
27 human saphenous vein samples evaluated for prostacyclin production before and after routine surgical preparation for coronary bypass grafting.
E
Exposure
Routine surgical preparation for coronary bypass grafting
C
Comparator
Freshly isolated human saphenous vein
O
Outcome
Prostacyclin production (spontaneous and stimulated rates)surrogate
Main Result
Absolute Event Rate: 7.1% vs 16.9%
Routine surgical preparation of saphenous veins for CABG impairs stimulated prostacyclin production, likely due to endothelial damage, which may contribute to vein graft occlusion.
Cite This Study
Angelini et al. (1987) studied Coronary artery bypass grafting (n=27). Routine surgical preparation vs. Freshly isolated human saphenous vein was evaluated on Stimulated prostacyclin production (pg.min-1 per mg wet weight). Routine surgical preparation of human saphenous vein for coronary bypass grafting significantly reduced stimulated prostacyclin production from 16.9 to 7.1 pg/min per mg wet weight.
