Among 1,006 patients undergoing coronary bypass reoperation from 1968 through 1982, 100 had a patent internal mammary artery graft. There were 88 men and 12 women with a mean age of 53.4 years and a mean interval between first and second operations of 56.6 months. Reasons for reoperation were vein graft closure in 26% of the patients, progressive disease in previously ungrafted arteries in 48%, and combined indications in 26%. One operative death occurred. There was no significant difference in morbidity when compared with a reference group of 906 reoperations in patients without IMA grafting. Complete revascularization was achieved in 64% of the patients; the mean number of grafts per patient was 1.6. Seven patients had a perioperative myocardial infarction, and eight mammary artery pedicles were damaged during reoperation.
在1968年至1982年接受冠状动脉搭桥再次手术的1006例患者中，100例患者的胸廓内动脉移植血管通畅。其中男性88例，女性12例，平均年龄53.4岁，首次手术与第二次手术之间的平均间隔时间为56.6个月。再次手术的原因包括：26%的患者静脉移植血管闭塞，48%的患者先前未移植血管的动脉出现进行性病变，26%的患者为综合指征。发生了1例手术死亡。与906例未进行胸廓内动脉移植的再次手术患者的参照组相比，发病率无显著差异。64%的患者实现了完全血运重建；每位患者移植血管的平均数量为1.6根。7例患者发生围手术期心肌梗死，8根胸廓内动脉蒂在再次手术期间受损。
