Migration of an embolized deployed stent from the left main with subsequent crushing: a new use for the IVUS...

Coronary stent dislodgement and loss carries significant morbidity and risk of infarction and thrombosis if left untreated. There have been multiple previous techniques for stent retrieval or deployment after stent loss including wire braiding, distal small balloon retrieval technique, snare use, forceps in large vessels and the stent crush technique. We report an unusual case of a largely deployed stent which was iatrogenically embolized retrogradely to the left main and its migration using an IVUS catheter with successful stent crushing in the proximal circumflex with good angiographic and medium term clinical outcome.
