Stingray球囊辅助正向夹层再入真腔技术精准穿刺开通冠状动脉慢性完全闭塞病变3例

Stingray-ADR Technique accurately puncture for chronic total occlusion of coronary artery:three cases reports

欧美、亚太以及中国的慢性完全闭塞(CTO)-经皮冠状动脉介入治疗(PCI)推荐流程均包括正向、逆向和正向夹层再入真腔技术(ADR)3大支柱技术。近年来Stingray球囊辅助下ADR术因其重复性高、安全高效受到广泛关注,而对CTO出口处有巨大分支者,ADR引起边支丢失风险较高须谨慎应用,尽量确保分叉前完成穿刺保留分支。本文报道3例分叉前精准ADR穿刺保留分支的CTO-PCI成功病例。

The CTO-PCI hybrid strategy in Europe,the United States,Asia Pacific and China all includes three pillars techniques of antegrade,retrograde and antegrade dissection reentry(ADR).In recent years,Stingray balloon assisted ADR has attracted wide attention due to its high repeatability,safety and efficiency.For those with large branches at the CTO exit,ADR has a high risk of side branch loss,and it should be applied with caution to ensure that the branch is preserved by puncture before bifurcation.Three successful cases of CTO-PCI with ADR accurately punctured retaining branches are reported below.
