After the introduction of the retrograde approach in percutaneous coronary intervention for chronic total occlusion (CTO), different kinds of strategies and techniques have been developed in order to achieve final success. However, it has not been fully demonstrated whether these strategies and techniques can really improve the final result. We observed one case, for which the initial attempt of the retrograde approach for a CTO lesion was unsuccessful despite the successful approach of a retrograde guidewire to the lesion, and with the second retrograde approach 3 years later being eventually successful by using various kinds of strategies and techniques. This case clearly demonstrates how the final success through the retrograde approach can be achieved by using a combination of the improved strategies and techniques for CTO lesions.
在经皮冠状动脉介入治疗慢性完全闭塞病变（CTO）中引入逆行技术后，为实现最终成功已开发出各种策略和技术。然而，这些策略和技术是否真能改善最终结果尚未得到充分证实。我们观察到1例病例，其对CTO病变首次尝试逆行技术时，尽管逆行导丝成功到达病变部位，但尝试仍未成功，3年后通过使用各种策略和技术再次进行逆行技术最终获得成功。该病例清楚地表明，通过联合应用改进的CTO病变策略和技术，可实现逆行技术的最终成功。
