Inadvertent anastomosis of the left internal mammary artery (LIMA) or a saphenous vein graft (SVG) to the great cardiac vein (GCV) is a rare complication of coronary artery bypass grafting (CABG). We present two cases with a LIMA to GCV and a SVG to GCV anastomosis, respectively, resulting in angina and dyspnea in the postoperative state. As an alternative to repeat CABG, both patients underwent percutaneous coronary intervention with percutaneous coil embolization or implantation of an Amplatzer vascular plug within the bypass graft to GCV conduit. This report highlights that percutaneous options exist for the relief of ischemic symptoms in this rare clinical setting.
左乳内动脉（LIMA）或大隐静脉移植物（SVG）意外吻合至冠状静脉（GCV）是冠状动脉旁路移植术（CABG）的一种罕见并发症。我们分别报告了两例LIMA与GCV吻合以及SVG与GCV吻合的病例，均导致术后出现心绞痛和呼吸困难。作为再次进行CABG的替代方案，两名患者均接受了经皮冠状动脉介入治疗，通过经皮线圈栓塞或在旁路移植至GCV的管道内植入Amplatzer血管封堵器。本报告强调，在这种罕见的临床情况下，存在缓解缺血症状的经皮治疗选择。
