Successful Retrieval of Dislodged Paclitaxel-eluting Stent with a Nitinol Loop Snare: A Case Report

Coronary stent dislodgment or embolization before deployment is a rare but challenging complication in interventional cardiology. Intracoronary embolization of the dislodged stent is associated with a high risk of coronary occlusion, due to thrombus formation and subsequent myocardial infarction. Furthermore, systemic embolization may cause severe cerebrovascular events. Nonsurgical retrieval strategies for this complication have been suggested, but bailout cardiac surgery may be indicated if percutaneous retrieval attempts fail. To our knowledge, this is the first case report of intracoronary drug-eluting stent dislodgment, and successful retrieval was accomplished by a loop snare technique. With the increasing trend of using drug-eluting stents in percutaneous coronary intervention, the likelihood of stent dislodgment or embolization may increase. It should be kept in mind, especially by coronary interventionists, how to manage this complication.
