A patient was referred for coronary artery bypass reoperation. After a left internal mammary artery was grafted to the left anterior descending coronary artery, the diseased but patent old saphenous vein graft was ligated. This resulted in severe myocardial failure, which was corrected only after restoration of flow through the old vein graft. We suggest the decision to ligate or replace an old vein graft should be individualized to avoid the risk of myocardial ischemia.
一名患者被转诊进行冠状动脉搭桥再次手术。在将左乳内动脉移植到左冠状动脉前降支后，对病变但仍通畅的旧大隐静脉移植物进行了结扎。这导致了严重的心肌衰竭，只有在恢复通过旧静脉移植物的血流后才得以纠正。我们建议，结扎或更换旧静脉移植物的决定应个体化，以避免心肌缺血的风险。
