title: Very late stent thrombosis after sirolimus-eluting stent implantation: evaluation by intravascular ultrasound and optical coherence tomography.
abstract: A 58-year-old man was admitted to our hospital with acute anterior myocardial infarction that occurred 4 years after single sirolimus-eluting stent (SES) implantation in the left anterior descending artery. He had been undergoing continuous dual antiplatelet therapy. Emergency coronary angiography showed total thrombotic occlusion and peri-stent contrast staining at the SES site. The lesion was evaluated using intravascular ultrasound (IVUS) and optical coherence tomography (OCT) after thrombectomy. Vessel remodeling was detected on IVUS, and multiple interstrut hollows and thrombi were observed on OCT. These findings were associated with very late stent thrombosis after SES implantation.
