【摘要】 冠状动脉瘘（CAF）是冠状动脉与心脏腔室或大血管之间的异常连接，而医源性CAF是一种非常罕见的经皮冠状动脉介入治疗（PCI）并发症。本病例报道1例在慢性完全闭塞（CTO）病变PCI术中，由于CTO导丝意外穿透左前降支，导致医源性左前降支至心大静脉冠状动静脉瘘形成并通过文献系统回顾PCI相关的CAF的处理。更多还原

【Abstract】 Coronary artery fistula(CAF) is an abnormal connection between the coronary artery and the cardiac chamber or large blood vessel. Iatrogenic coronary artery f istula is a very rare complication of percutaneous coronary intervention(PCI). We report a case of iatrogenic lef t anterior descending branch(LAD) to great cardiac vein coronary arteriovenous f istula resulting f rom unexpected penetration of chronic total occlusion(CTO) guidewire through LAD during CTO intervention,and reviews the management of PCI-related CAF through the literature system.更多还原
