Unusual complication: successful transcatheter extraction of an embolized coronary stent during percutaneous coronary intervention

Despite advances in coronary angiography, systemic or coronary embolization of the stent remains a potentially lethal complication, although rarely seen. Stent embolization frequently happens following percutaneous coronary intervention in tortuous and calcified segments, with an incidence probability of 0.29% to 0.32%. It is linked to troublesome problems including complete loss of flow, stent thrombosis, coronary artery damage during retrieval procedures, and stent embolization into the systemic circulation. This uncommon consequence might induce significant stress for operators throughout the process. Numerous techniques exist for the extraction of embolized material, with operator expertise and laboratory equipment being the primary determinants of the selected method. We reviewed the techniques used to extract the stent that became loosened in the primary coronary.
