The retrograde approach is an effective therapeutic strategy for chronic total occlusion (CTO) intervention. In CTO cases, the retrograde approach from the opposite coronary artery is not always applicable. In certain left anterior descending (LAD) CTO cases, the distal LAD is filled from the septal channel where it is supplied by the proximal septal route. We report two LAD CTO cases of percutaneous coronary intervention (PCI) conducted with a wire from the proximal septal branch to the distal septal channel using the retrograde approach.
逆向入路是慢性完全闭塞（CTO）介入治疗的一种有效策略。在CTO病例中，从对侧冠状动脉进行逆向入路并不总是可行的。在某些左前降支（LAD）CTO病例中，LAD远端由间隔支近端途径供血，通过间隔通道实现充盈。我们报告了两例采用逆向入路，经间隔支近端将导丝送至间隔通道远端进行经皮冠状动脉介入治疗（PCI）的LAD CTO病例。
