【摘要】开通慢性完全闭塞病变仍然是经皮冠状动脉介入治疗的最后挑战之一。作为经典的前向技术的重要补充，逆向技术是该治疗的重要方法。尽管经常被用于最复杂的病变，但逆向技术成功率高，并发症发生率相对较低。自逆向技术出现以来，已经有了重要改进，使其更安全、更快、更成功。

【Abstract】Chronic total occlusion recanalization still remains one of the last challenge of percutaneous coronary intervention.As one of the most important amendments technique，retrograde recanalization has become an essential supplement to the classical antegrade approach.It has a high success rate with a low complication，despite higher utilization in the most complex patients.Since its initial description，important evolutions have occurred and made the technique safer，faster and more successful.

随着技术以及器械的发展，尽管慢性完全闭塞（chronic total occlusion，CTO）病变开通成功率较前明显提高，但仍然是经皮冠状动脉介入治疗（percutaneous coronary intervention，PCI）最后堡垒。（剩余12834字）
