Abstract：
UNASSIGNED: Chronic total occlusion (CTO) lesions contain various collateral channels. Only a few reports have described CTO with collateral channels from the bronchial arteries.
UNASSIGNED: Herein, we report the case of a 59-year-old man with a left circumflex (LCX) coronary artery CTO with collateral channels from the bronchial arteries. The J-CTO score was 1. After confirming myocardial viability and myocardial ischaemia using a stress myocardial perfusion imaging test, we performed percutaneous coronary intervention for the CTO lesion. Successful revascularization was achieved by adopting the antegrade approach with the angiogram guidance of distal visualization using the bronchial artery.
UNASSIGNED: Notably, there are no other reports of LCX CTO with collateral channels from the bronchial artery. Distal visualization of the distal true lumen is essential for the success of the antegrade approach. Furthermore, appropriate distal visualization helps to avoid unnecessary retrograde approaches and reduce complications.

摘要：
■慢性完全闭塞（CTO）病变包含各种侧支通道。只有少数报道描述了具有支气管动脉侧支通道的CTO。
■这里，我们报告了一例59岁的男性患者，其左回旋支（LCX）冠状动脉CTO具有来自支气管动脉的侧支通道。J-CTO评分为1。在使用压力心肌灌注成像测试确认心肌生存力和心肌缺血后，我们对CTO病变进行了经皮冠状动脉介入治疗.通过采用顺行方法并使用支气管动脉进行远端可视化的血管造影引导，可以成功实现血运重建。
■值得注意的是，没有其他LCXCTO与支气管动脉侧支通道的报道.远端真腔的远端可视化对于顺行方法的成功至关重要。此外，适当的远端可视化有助于避免不必要的逆行入路并减少并发症.
