Usefulness of Intracoronary Angioscopy for Elucidating the Cause of Subacute Thrombosis After Stenting

Abstract

Stent thrombosis is rare with anti-platelet therapy, which consists of aspirin and ticlopidine as a post-stenting administration. A 77-year-old man had repeated stent thrombosis, which was not predicted by coronary angiography, despite using contemporary periprocedural anti-platelet therapy. Only intravascular fiberscopy was able to detect the cause of the stent thrombosis. (Jpn Circ J 2001; 65: 232 -235)

Death caused by simultaneous subacute stent thrombosis of sirolimus-eluting stents in left anterior descending artery and left circumflex artery

“…In addition, this patient did not have risk factors of the development of ST such as diabetes, old age, low ejection fraction, moderate or heavy calcification, and postprocedural TIMI flow b3 [6]. According to cases reported recently, it has been shown by intra vascular fibro-angioscopy that the cause of ST was elucidated to be the partial protrusion of the stent-struts into the lumen [7]. As far as we know, our case was the first case of subacute ST for the same time confirmed by coronary angiography at Cypher stents in the LAD and LCx.…”
