Abstract

The entrapment and detachment of a cutting balloon catheter during the treatment of in-stent restenosis (ISR) has never been reported. We describe a case of a cutting balloon catheter impinged within the stent mesh, which fractured during pull-back. We report a case of a 52-year old male patient who had been stented for the management of critical stenosis of the proximal left anterior descending artery (LAD) seven months previously. A follow-up coronary angiogram revealed a critical diffuse ISR at the proximal LAD, so cutting balloon angioplasty was tried. The guide wire went through the lesion without difficulties ; however the cutting balloon was entrapped in the proximal LAD during advancement. We tried to pull-back the cutting balloon, but the balloon fractured, and disconnected at the mid-shaft portion. The broken distal cutting balloon impacted in the proximal LAD and left main stem, and the proximal shaft of balloon catheter was floating in the descending aorta. ST segment elevation was demonstrated on ECG monitoring ; as a result emergent coronary bypass surgery was performed. The broken catheter was removed from left coronary artery successfully.
