[Coronary Artery Perforation Secondary to Primary Percutaneous Coronary Intervention;Report of a Case].

Stent perforation of a coronary artery during percutaneous coronary intervention (PCI) is a rare but life-threatening complication. A 70-year-old man was admitted to our hospital for management of acute coronary syndrome. PCI was attempted for the left circumflex artery(LCX);however, catheterization was complicated by perforation of the LCX by the stent. He developed cardiac tamponade and was resuscitated using percutaneous cardiopulmonary support. Emergency surgery( ligation of the LCX and aorto-coronary bypass grafting for the distal LCX) was performed. His postoperative course was uneventful, and the patient was discharged on the 20th postoperative day. Collaboration between cardiologists and surgeons is essential to salvage such a critical patient.
