Saphenous Vein Graft Stenosis
Saphenous vein graft (SVG) stenosis or occlusion is the Achilles heel for a more liberal use of this type of graft in coronary artery bypass surgery (CABG) for myocardial revascularization.

At the end of the first year 15% of SVG can be occluded due to intimal hyperplasia. Perfect surgical technique, careful handling of the saphenous vein avoiding graft overdistension and aspirin use for life (or other antiplatelet agent) are important points for achieving a patent vein.
