Entrapment of an intravascular ultrasonography（IVUS）catheter is an infrequent but serious complication associated with percutaneous coronary intervention（PCI). We report a case of successful surgical treatment of an IVUS catheter entrapped in a coronary stent after PCI. An-80-year-old man was admitted to a hospital with sudden anterior chest pain. He underwent PCI to left circumflex branch（Cx）and left anterior descending artery（LAD), followed by IVUS to ascertain stent expansion of the LAD stent. The IVUS catheter became entangled in the stent and could not be withdrawn from the outside. The patient was transferred to our hospital for its surgical removal. For the emergent surgery, we opened the stent region in the LAD and directly removed the IVUS catheter with the twisted stent. The opened place in the LAD was directly closed. Additional coronary bypass grafting involving two vessels was performed. The postoperative course was uneventful with no graft occlusion.
