Rupture of coronary artery bypass graft during percutaneous coronary intervention is a rare but serious complication. These perforations are often associated with myocardial infarction, pericardial tamponade, immediate or delayed, emergency bypass surgery and even death. We report an interesting case where perforation of a saphenous vein graft occurred after direct stenting, resulting in a very rare complication of superior vena cava (SVC) syndrome.
