Percutaneous coronary intervention (PCI) of heavily calcified vessels poses several problems including difficulty in delivering stents to the target lesion. Effective strategies include rotational atherectomy and the use of a "buddy" wire, the latter acting as a track that directs the stent away from the vessel wall. There are no reports in the literature of using a second "buddy" wire when one fails. We report on a case of a second "buddy" wire saving the day during PCI of a highly calcified right coronary artery wherein the stent failed to reach the lesion until the second wire was deployed.
严重钙化血管的经皮冠状动脉介入治疗(PCI)存在诸多问题,包括将支架输送至靶病变困难。有效的策略包括旋磨术和使用“伙伴”导丝,后者可作为引导支架远离血管壁的轨道。文献中尚无关于一根“伙伴”导丝失败后使用第二根“伙伴”导丝的报道。我们报告了一例在高度钙化的右冠状动脉PCI过程中,第二根“伙伴”导丝发挥作用的病例,在第二根导丝置入前,支架一直无法到达病变部位。
