Fractures occur in association with manipulation and because of the complexity of the coronary artery, and they can cause a series of serious complications, such as myocardial infarction and secondary thrombosis. Common treatments for fractured guidewires include conservative, interventional and surgical methods.
A 67-year-old male was admitted to our institute. He had recurrent chest tightness and chest pain for half a month, which worsened in one day. He was diagnosed with acute non-ST-segment elevation myocardial infarction. Guidewire fracture was caused by improper manipulation during percutaneous coronary intervention. We successfully performed rotational atherectomy to remove the fractured guidewire. His symptoms, and condition improved 6 weeks after the removal of fractured guidewire.
Physicians should have higher requirements for the quality of the guidewires and operation techniques.
由于冠状动脉的复杂性，介入操作时常会导致导丝断裂，进而引发一系列严重并发症，如心肌梗死和继发性血栓形成。常见的断裂导丝处理方法包括保守治疗、介入治疗和手术治疗。
一名 67 岁男性患者因反复胸闷胸痛半个月，1 天加重入住我院。入院诊断为急性非 ST 段抬高型心肌梗死。该患者为经皮冠状动脉介入治疗时因操作不当导致导丝断裂。我们成功实施了旋磨术取出断裂导丝。断裂导丝取出 6 周后，患者症状、病情改善。
术者应提高对导丝质量和操作技术的要求。
