The authors report a case of accidental loss of a coronary stent in the coronary arteries and its migration into the circumflex artery. This complication occurred during revascularisation of the left anterior descending artery. In view of a dissection at the site of angioplasty and the migration of the stent, emergency surgery was undertaken comprising bypass grafting of the left anterior descending and arteriology of the left circumflex arteries to recover the stent. This is a rare complication, the frequency is probably underestimated. The authors discuss the factors predisposing to failure of implantation and the means of recovering the stents. The consequences of loss of a stent in the coronary or systemic circulations are also commented.
作者报告了1例冠状动脉支架在冠状动脉内意外丢失并迁移至回旋支动脉的病例。该并发症发生在左前降支血管重建期间。鉴于血管成形术部位出现夹层以及支架迁移，遂进行了急诊手术，包括对左前降支进行搭桥移植以及对左旋支动脉进行动脉介入治疗以取出支架。这是一种罕见的并发症，其发生率可能被低估了。作者讨论了导致植入失败的因素以及取出支架的方法。还对冠状动脉或体循环中支架丢失的后果进行了评论。
