Coronary perforation is an infrequent, but serious complication of percutaneous coronary intervention (PCI), and is more likely to occur with complex (such as chronic total occlusion) PCI and use of atheroablative devices. For main vessel perforations, the "dual catheter" technique is usually employed in which a balloon is delivered over the first guide catheter to stop bleeding, whereas the covered stent is delivered through a second guide catheter. This is required because the large profile of the currently commercially available covered stents precludes fitting within even an 8-French guide together with a balloon. However, coil embolization for distal artery wire perforation and collateral vessel perforation can be achieved through a microcatheter that can fit along with a balloon within an 8-French guide catheter, obviating the need for a second guide catheter. We describe a case in which a distal artery wire perforation was successfully treated using a single 8-French guide catheter.
冠状动脉穿孔是经皮冠状动脉介入治疗(PCI)中一种少见但严重的并发症,在复杂PCI(如慢性完全闭塞病变)及使用粥样斑块消融装置时更易发生。对于主要血管穿孔,通常采用“双导管”技术,即通过第一根引导导管送入球囊以止血,而覆膜支架则通过第二根引导导管送入。之所以需要这样做,是因为目前市售的覆膜支架尺寸较大,即使与球囊一起也无法放入8F引导导管内。然而,对于远端动脉导丝穿孔和侧支血管穿孔,可通过能与球囊一起放入8F引导导管内的微导管进行弹簧圈栓塞,从而无需第二根引导导管。我们报道一例使用单一8F引导导管成功治疗远端动脉导丝穿孔的病例。
