Chronic total occlusion (CTO) is a frequent finding in patients with coronary artery disease and when clinically indicated, remains one of the most challenging subsets for intervention. Although successful recanalization rates of CTO have remained suboptimal in percutaneous coronary intervention, evolving techniques including retrograde approach, have raised hopes for improving the overall success. Reverse controlled antegrade and retrograde subintimal tracking is the most commonly used out of various retrograde approaches. In this review, the author has thrown light on a step-by-step approach of this technique, its standardization, various modifications along with complications.
慢性完全闭塞（CTO）在冠状动脉疾病患者中很常见，在有临床指征时，仍然是最具挑战性的干预亚组之一。尽管在经皮冠状动脉介入治疗中，CTO的成功再通率一直不尽人意，但包括逆向途径在内的不断发展的技术，为提高总体成功率带来了希望。逆向控制顺行和逆行内膜下寻径是各种逆向途径中最常用的方法。在这篇综述中，作者阐述了该技术的逐步操作方法、标准化、各种改良以及并发症。
