Entrapment of guidewire in the coronary stent during percutaneous coronary intervention.

A 76-year-old man presented with chest discomfort. On coronary angiography, subtotal occlusion in the mid-right coronary artery (RCA) and 60 % tubular stenosis in the distal RCA were revealed. Two intracoronary stents could be placed in the RCA without any difficulty. However, the guidewire could not be removed. The intraoperative finding showed that the guidewire had become entrapped in the coronary stent. The guidewire was successfully removed and emergency coronary bypass grafting was performed.
