Abstract

Although stent entrapment is a rare event during percutaneous coronary intervention, stent entrapment can cause stent breakage or loss, which results in fatal complications such as stent embolism or acute myocardial infarction. We report one case of stent entrapment that was successfully treated by a snare via a contralateral transfemoral approach.

Figure

• 

  FIG. 1 Coronary angiography showed no significant in-stent restenosis in the left anterior descending artery (LAD) and chronic total occlusion in the left circumflex artery (LCX).

• 

  FIG. 2 During percutaneous coronary intervention, a half-degloved stent strut was observed in the LCX (arrow).

• 

  FIG. 3 A half-degloved stent strut and balloon catheter that were removed by use of a loop snare.
