Very Late Stent Thrombosis Related to Fracture of a Sirolimus-Eluting Stent

Abstract

Although late stent thrombosis is a very rare complication after a drug-eluting stent implantation, this could induce significant sequelae. Several mechanisms for very late stent thrombosis have been suggested. We experienced a new possible mechanism of very late stent thrombosis after the implantation of a sirolimus-eluting stent. A sirolimus-eluting stent fracture might induce mechanical injury of the endothelium and then thrombotic occlusion at 24 months after the stent procedure.
