Abstract:Background: High-pressure distension during harvesting damages the saphenous vein (SV) and may contribute to subsequent coronary artery bypass graft (CABG) occlusion.

We tested the effects of a vasodilator solution containing the conventional agent papaverine (Pap) mixed with heparinized blood on the pressure necessary to overcome SV spasm and on the structure.
