Abstract

A 46-year-old man underwent two coronary bypass operations and three percutaneous interventions over a period of 18 years. A non-functioning internal mammary artery (IMA) graft, was observed shortly after the second surgery. This graft was anastomosed to the left anterior descending (LAD) that had adequate flow from an older vein graft placed during the first surgery. Over the ensuing 8 years, the IMA graft regained patency after progressive occlusive disease in the competing vein graft.

摘要

一名46岁男性在18年的时间里接受了两次冠状动脉搭桥手术和三次经皮介入治疗。在第二次手术后不久，发现一支无功能的乳内动脉（IMA）移植物。该移植物与左前降支（LAD）吻合，而左前降支通过首次手术时植入的一支较旧的静脉移植物有充足的血流。在接下来的8年里，在与之竞争的静脉移植物发生进行性闭塞性疾病后，IMA移植物恢复了通畅。
