Two cases of very late stent thrombosis after implantation of a sirolimus-eluting stent presenting as AMI

Abstract

Stent thrombosis after sirolimus-eluting stent (SES) implantation has been reported to occur at 6 hours to 26 months after the procedure and usually within 2 weeks after discontinuation continuation of antiplatelet medication. However, there are very few reports of stent thrombosis after 2 years. We report 2 cases of very late stent thrombosis after implantation of a sirolimus-eluting stent presenting as acute myocardial infarction (AMI). These late thromboses occurred about 2 years after SES implantation and over 1.5 years after discontinuation of ticlopidine.
