Stent embolization is a rare but acknowledged complication of placement of disarticulated (half) Palmaz-Schatz stents. We report a case in which we diagnosed a previously unrecognized, embolized, undeployed half-stent in the distal LAD, causing slow flow, and then deployed the stent where it lay, resulting in improved flow. The literature on treatment of coronary stent embolization and on cutting and preparing half-stents for deployment is discussed.
支架栓塞是已分离（半）Palmaz-Schatz支架置入术一种罕见但公认的并发症。我们报告了一例病例，其中我们诊断出在左前降支远端有一个先前未被识别的、已栓塞的、未展开的半支架，导致血流缓慢，然后在其所在位置展开该支架，使血流得到改善。文中还讨论了关于冠状动脉支架栓塞治疗以及切割和准备用于展开的半支架的文献。
