An avoidable complication of percutaneous coronary intervention-entrapment of stent and disconnected balloon catheter.
During percutaneous coronary intervention, entrapment of catheter materials is a rare but life-threatening complication that sometimes requires emergency surgical treatment. Coronary artery stents have been developed to prevent acute coronary closure and reduce restenosis after coronary angioplasty. The most frequently reported complications of coronary stents are related to stent thrombosis and anticoagulation problems. This case study describes a 60-year-old female who had stable angina pectoris and underwent stent insertion into the left circumflex artery. Unfortunately, the coronary stent with balloon catheter was entrapped while crossing the angulated segment between the left circumflex and left main coronary artery. The stent catheter was surgically removed, and the patient underwent coronary artery bypass grafting successfully. Physicians should keep in mind that extremely angulated segments may reduce the successful rate of coronary stenting and contribute to the stent entrapment complication.
