The entrapment, fracture, and dislodgement of catheterization devices during percutaneous coronary intervention (PCI) are rare complications, for which cardiac surgery is sometimes required. Here, we encountered a rare but instructive case of balloon catheter fracture during PCI. Although there have been some reports of guidewire fracture in PCI, reports on balloon catheter fracture are very rare to our knowledge. A simulation test to examine the mechanism of balloon catheter fracture revealed that overuse of the balloon catheter, both for kissing balloon inflation and balloon anchor, was highly likely to have been the cause of the fracture.
在经皮冠状动脉介入治疗（PCI）期间，导管插入装置的卡压、断裂和移位是罕见的并发症，有时需要进行心脏手术。在此，我们遇到了一例PCI期间球囊导管断裂的罕见但具有启发性的病例。尽管已有一些关于PCI中导丝断裂的报道，但据我们所知，关于球囊导管断裂的报道非常罕见。一项检查球囊导管断裂机制的模拟试验表明，球囊导管在用于对吻球囊扩张和球囊锚定方面的过度使用很可能是断裂的原因。
