During coronary angiography knotting of a coronary catheter is a recognised complication. It commonly results through excessive manipulation of a catheter in an attempt to engage the right coronary artery. Although simple manoeuvres of the catheter can often result in resolution of a kink, tighter knots may not be amenable to such measures. There is, however, little published material regarding its best management. We present five cases of cardiac catheterisation complicated by catheter knotting and present a novel percutaneous technique for their reduction.
在冠状动脉造影过程中，冠状动脉导管打结是一种公认的并发症。它通常是由于在试图插入右冠状动脉时对导管进行过度操作所致。尽管对导管进行简单操作通常可使扭结解除，但较紧的结可能无法通过此类措施解决。然而，关于其最佳处理方法的已发表资料很少。我们报告了5例因导管打结而并发的心脏导管插入术病例，并提出了一种新的经皮复位技术。
