title: Nine-year follow-up of progressive peri-stent contrast staining after Cypher sirolimus-eluting stent implantation: a case report.
abstract: A 62-year-old male underwent three percutaneous coronary interventions involving four bare metal stents and six Cypher sirolimus-eluting stents within 1 month. At the latest coronary angiographic examination, all of the Cypher stents, but none of the bare metal stents, exhibited peri-stent contrast staining. Moreover, these findings had progressively worsened over time, especially for lesions where two stents came into contact or stent fracture had occurred. It is rare for Cypher stent implantation to result in progressive peri-stent contrast staining, but patients who are treated with these stents should be carefully followed-up, including for stent thrombosis.
