The retrograde approach is a novel technique for improving the success rate of guidewire passage through chronic total occlusion (CTO). In addition, this technique, especially when intravascular ultrasound-guided reverse controlled antegrade and retrograde subintimal tracking is employed, may help the operator to save on the contrast media used. In the case reported here, only 10 ml of contrast media was used in percutaneous coronary intervention for CTO.
逆行技术是提高慢性完全闭塞（CTO）导丝通过成功率的一种新方法。此外，这种技术，特别是在血管内超声引导下的逆向控制性顺行和逆行内膜下跟踪时，可能有助于操作者节省造影剂的使用。在本例报告中，CTO 的经皮冠状动脉介入治疗仅使用了 10 毫升造影剂。
