Abstract:

Degeneration and occlusion of saphenous vein grafts (SVG) has been a serious problem in patients who underwent coronary artery bypass surgery. Although a variety of treatment methods have been developed for the SVG occlusion, the most suitable option is not yet known. Because re-do surgical intervention has high morbidity and mortality, most of the center prefer to percutaneous coronary intervention in this group of patients. Past to present many studies and meta-analysis were made compared with balloon angioplasty, covered stents, bare metal stents and drug-eluting stents in SVG lesions. Large-scale, randomized, controlled clinical studies are needed to demonstrate the efficiency and safety of the use of drug eluting stents which appear to be comparatively the most effective method.
