[A late coronary aneurysm after sirolimus stent implantation which was treated with coronary graft stent].

Drug eluting stents are being used frequently because of their less restenotic properties. However, their effect on preventing neo-intimal hyperplasia may cause many adverse effects such as coronary artery aneurysm (CAA). We report a case that presented with a CAA which was the latest developed CAA after the implantation of drug eluting stents in literature so far. A 57-year-old male presented with dyspnea and typical angina on effort. Coronary angiography was performed. A large CAA was detected at the site of a drug eluting stent which was implanted in the LAD artery 5.5 years ago. It was treated with a coronary stent graft successfully.
