title: Very late stent thrombosis of sirolimus-eluting stent combined with late stent malapposition and aneurysm formation.
abstract: Late complications of drug-eluting stent, such as stent malapposition or aneurysm formation have emerged major concern. However, there is no available standard therapeutic guideline about them because the clinical course of those is variable and long-term follow- up data is not sufficient. A case presented here is acute ST-elevation myocardial infarction as a result of very late stent thrombosis developed in a patient with stent malapposition and peri-stent aneurysm formation 52 months after sirolimus-eluting stent implantation. In conclusion, more careful long-term follow-up studies are required to access the significance of these late vascular pathologic changes.
