Coronary artery perforation is a rare but potentially lethal complication during percutaneous transluminal coronary angioplasty (PTCA). To avoid pericardial tamponade, it has been suggested that perforating wires or balloons should not be withdrawn and that the patient should be transferred immediately to surgery. We report a case with a perforating and broken intracoronary guide wire which was successfully extracted using a Dotter intravascular retriever catheter. The only consequence was a small pericardial effusion not requiring pericardial puncture. Thus, emergency surgery is not inevitable after coronary artery perforation caused by thin intracoronary guide wires.
冠状动脉穿孔是经皮腔内冠状动脉成形术（PTCA）期间一种罕见但可能致命的并发症。为避免心包填塞，有人建议不应拔出穿孔导丝或球囊，患者应立即转至外科手术。我们报告一例冠状动脉内导丝穿孔并断裂的病例，该导丝使用Dotter血管内回收导管成功取出。唯一的后果是少量心包积液，无需心包穿刺。因此，冠状动脉内细导丝导致的冠状动脉穿孔后并非必然需要急诊手术。
