A 61-year-old man with a history of percutaneous coronary intervention (PCI) of the mid right coronary artery (RCA) with a drug eluting stent (DES), presented with non-ST segment elevation myocardial infarction. Coronary angiography demonstrated complex disease of the distal RCA as well as in-stent stenosis of the previously placed mid RCA stent. The patient underwent bifurcation PCI of the distal RCA followed by attempted intervention with a DES on the mid RCA lesion. The stent could not cross the lesion and eventually became dissociated from its delivery system. The lost stent was successfully retrieved using two different snaring systems. The procedure was terminated without further attempts for stent delivery. The patient had an uneventful recovery and underwent successful PCI of the mid RCA lesion one month later.
一名61岁男性，有右冠状动脉中段经皮冠状动脉介入治疗（PCI）并植入药物洗脱支架（DES）的病史，此次因非ST段抬高型心肌梗死就诊。冠状动脉造影显示右冠状动脉远端存在复杂病变以及先前植入的右冠状动脉中段支架内狭窄。该患者接受了右冠状动脉远端分叉PCI，随后尝试对右冠状动脉中段病变植入DES。支架无法通过病变部位，最终与输送系统分离。使用两种不同的圈套系统成功取出了丢失的支架。手术终止，未进一步尝试输送支架。患者恢复顺利，一个月后成功对右冠状动脉中段病变进行了PCI。
