Very Late Stent Thrombosis 5 Years After Implantation of a Sirolimus-Eluting Stent Observed by Angioscopy and Optical Coherence Tomography
Images of Coronary Angiography and OCT of Pre– and Post–Percutaneous Coronary Intervention (A) Initial coronary angiography demonstrated severe stenosis with a contrast filling defect in the sirolimus-eluting stent (SES) implantation site of the left anterior descending artery (small arrows) . Dashed red line shows SES implantation site. (B) Optical coherence tomography (OCT) revealed massive thrombus in the SES (solid arrows) at the site of the open arrow . (C) Vessel patency was restored after aspiration procedure. Dashed red line shows SES implantation site. (D) The OCT image demonstrated restored vessel patency at the site of the open arrow .
