Device-related complications during percutaneous coronary intervention (PCI), such as catheter or balloon shaft separation, are uncommon but potentially life-threatening. Effective retrieval techniques are crucial to avoid surgical intervention. We report a rare case of simultaneous separation of a guide extension catheter tip and balloon shaft, successfully managed using a two-wire and snare technique. A 58-year-old man with a history of familial hypercholesterolemia underwent PCI for in-stent restenosis in the mid right coronary artery (RCA), previously treated with a sirolimus-eluting stent. After successful lesion preparation using a scoring balloon and drug-coated balloon via a 6-Fr guide extension catheter, the extension catheter became stuck in a tortuous segment. Attempted withdrawal resulted in distal tip separation. A 2.0-mm balloon was deployed inside the tip for trapping, but during retrieval the balloon shaft itself fractured. To retrieve both fragments, a second guidewire was advanced outside the separated tip with the aid of a microcatheter, followed by deployment of a Goose Neck snare. The snare successfully grasped the initial guidewire, enabling the en bloc retrieval of both the guide extension tip and the broken balloon shaft. No complications occurred, and final angiography confirmed optimal flow. This case illustrates a practical and effective two-wire plus snare technique for managing simultaneous device fragment separation during PCI. Familiarity with bailout strategies such as this may help avoid surgical retrieval or further complications in similar settings.
经皮冠状动脉介入治疗(PCI)期间与器械相关的并发症,如导管或球囊杆分离,虽不常见但可能危及生命。有效的取出技术对于避免手术干预至关重要。我们报告一例罕见的导引导管延长管尖端与球囊杆同时分离的病例,采用双线和圈套器技术成功处理。一名有家族性高胆固醇血症病史的58岁男性因右冠状动脉中段支架内再狭窄接受PCI,该部位先前植入了西罗莫司洗脱支架。通过6F导引导管延长管使用刻痕球囊和药物涂层球囊成功进行病变预处理后,延长管卡在了一个迂曲节段。试图拔出导致远端尖端分离。在尖端内植入一个2.0mm的球囊进行圈套,但在取出过程中球囊杆本身断裂。为了取出两个碎片,在微导管的辅助下,将第二根导丝推进到分离的尖端外部,随后部署鹅颈圈套器。圈套器成功抓住了初始导丝,从而能够整块取出导引导管延长管尖端和断裂的球囊杆。未发生并发症,最终血管造影证实血流良好。本病例说明了一种实用且有效的双线加圈套器技术,用于处理PCI期间器械碎片同时分离的情况。熟悉此类补救策略可能有助于在类似情况下避免手术取出或进一步的并发症。
