Coronary chronic total occlusion (CTO) is a frequent finding in patients with coronary artery disease. It remains one of the most challenging subsets, accounting for 10-20% of all percutaneous coronary interventions (PCI). Although remarkable progress in PCI has been made, it is reasonable to state that successful recanalization of CTO represents the “last frontier" of PCI. PCI of CTOs has been limited historically by technical success rates of 50-70%. The introduction of enhanced guidewires, microcatheter, channel dilatator with increasing operator experience, and innovative techniques such as the retrograde approach have raised hopes for better outcomes. This article goes into depth into various strategies of retrograde approach in CTO.
冠状动脉慢性完全闭塞（CTO）在冠心病患者中很常见。它仍然是最具挑战性的亚组之一，占所有经皮冠状动脉介入治疗（PCI）的10%-20%。尽管PCI已取得显著进展，但可以合理地说，CTO的成功再通代表了PCI的“最后前沿”。历史上，CTO的PCI技术成功率为50%-70%，受到一定限制。随着增强导丝、微导管、通道扩张器的引入以及术者经验的增加，还有诸如逆向技术等创新技术的出现，人们对获得更好的治疗效果充满了希望。本文深入探讨了CTO逆向技术的各种策略。
