Key result
In situ crushing with two overlapping stents successfully manages an unretrievable dislodged coronary stent.
Why the study?
Coronary stent dislodgement is a rare but potentially serious complication of PCI requiring effective management strategies.
Case Report (n=1)
In situ stent crushing with overlapping stents is a viable and technically successful strategy for managing a dislodged coronary stent when retrieval is not feasible.
May offer a bailout option when stent retrieval fails; leaves open questions on long-term outcomes and generalizability.
Coronary stent dislodgement is a rare but potentially serious complication of percutaneous coronary intervention (PCI). We report the case of a 47-year-old male presenting with chest pain and elevated troponin, and treated for non-ST elevation myocardial infarction. Coronary angiography revealed a distal left circumflex artery thrombotic occlusion, and PCI was attempted. During the procedure, resistance to stent advancement and repeated manipulation led to stent dislodgement in the distal vessel. The complication was recognized on stent boost fluoroscopic imaging. Due to technical difficulty and distal location, stent retrieval was not attempted. Instead, the dislodged stent was successfully crushed in situ using two additional overlapping stents, achieving satisfactory angiographic results. This case highlights the importance of early recognition, careful technique, and appropriate management strategies in coronary PCI to prevent adverse outcomes.

Naqvi et al. (2026) conducted a case report in Non-ST elevation myocardial infarction with coronary stent dislodgement (n=1). Stent crushing in situ (using two additional overlapping stents) was evaluated on Angiographic results. Stent crushing in situ using two overlapping stents successfully managed a dislodged coronary stent during PCI, achieving satisfactory angiographic results.
