A 34-year-old man with a prior history of Hodgkin's disease and coronary artery bypass surgery for radiation-induced left main disease presented with persistent chest pain. Cardiac catheterization showed near simultaneous filling of the venous system during arterial injection and could not precisely delineate the insertion point of the vein graft anastamosis to the diagonal branch, and the patient was referred for coronary computed tomography angiography (CTA). CTA demonstrated that the anastamosis of the graft was with a cardiac vein. This case illustrates the valuable complementary role of both angiographic methodologies in confirming a complex anatomic diagnosis.
一名34岁男性，既往有霍奇金淋巴瘤病史，因放射性所致左主干病变接受过冠状动脉搭桥手术，现出现持续性胸痛。心脏导管检查显示，动脉注射时静脉系统几乎同时显影，无法精确确定静脉移植物与对角支的吻合插入点，遂将该患者转诊进行冠状动脉计算机断层血管造影（CTA）检查。CTA显示移植物与一条心脏静脉吻合。本病例说明了两种血管造影方法在证实复杂解剖诊断方面具有重要的互补作用。
