Definition of SVG Failure
Saphenous vein graft occlusion is defined as a complete, 100% occlusion of a saphenous vein graft. [1]
Saphenous vein failure is defined as an occlusion of the vein graft or a 75% or greater stenosis.
Potential for Pre-Operative SVG Failure
It should be noted that studies of SVGs that are not implanted show that about 1% of veins are already stenosed by > 50% before implantation[2].
