Saphenous veins used as aortocoronary conduits develop early and late structural changes, including stenosis and complete occlusion, with widely varying functional significance.
This review describes the early and late structural changes, including stenosis and occlusion, that occur in saphenous vein grafts used for coronary bypass.
May warrant close SVG monitoring post-CABG; leaves open optimal conduit selection and prevention strategies.
ince its introduction 30 years ago, numerous patients have benefited from coronary arterial bypass grafting.Despite its benefits to most patients, coronary bypass, of course, is not free of complications.Stenosis or complete occlusion of venous grafts used as aortocoronary conduits still occurs.While all venous grafts develop some morphologic changes, the degree and functional significance of the changes vary widely.This article describes structural changes observed early and late in saphenous veins that are used as aortocoronary conduits.

William C. Roberts (1997) conducted a review in Coronary arterial bypass grafting. Venous autografts (saphenous veins) was evaluated on Structural changes (stenosis, occlusion, morphologic changes). Saphenous veins used as aortocoronary conduits develop early and late structural changes, including stenosis and complete occlusion, with widely varying functional significance.
