Background
Coronary artery revascularization with saphenous veins (saphenous vein grafts or SVGs) has become a modern surgical standard for the treatment of coronary artery disease. This technique can be employed when a native coronary artery is blocked, thus causing a reduction or obstruction in blood flow. Cardiac surgeons use the sutured graft to provide a connection between the aorta and the coronary artery beyond the area of obstruction, so that blood flow may resume.
Despite their ability to restore blood flow, SVG stenosis is a common problem. Its incidence is 15-30% one year after surgery, and it increases to 50% 10 years after surgery.
