In cases where conventional aortocoronary grafts cannot be used, No-React bovine internal mammary artery is a possible alternative. The aim of this study was to assess the patency and clinical performance of bovine internal mammary artery as a coronary bypass conduit, using 64-slice computed tomography coronary angiography. Eleven patients (mean age, 68.2 + or - 5.9 years) received 11 bovine grafts between 2002 and 2006. Eight of these patients were alive after a mean follow-up of 29.4 + or - 16.3 months. Their mean additive EuroSCORE was 6.5 + or - 3.2. The mean number of distal anastomoses was 2.5 + or - 0.5. Six grafts were anastomosed to the right coronary artery, 2 to the left anterior descending artery, and 3 to the circumflex artery. All 11 bovine grafts were found to be occluded after 14.1 + or - 3.6 months. This demonstrates very poor results with the bovine coronary graft, thus we do not recommend its use, and we suggest considering an hybrid approach in selected cases.
在无法使用传统主动脉冠状动脉移植的情况下，无反应牛乳内动脉是一种可能的替代选择。本研究的目的是使用64层计算机断层扫描冠状动脉造影评估牛乳内动脉作为冠状动脉搭桥管道的通畅性和临床性能。2002年至2006年间，11例患者（平均年龄68.2±5.9岁）接受了11次牛移植。这些患者中有8例在平均随访29.4±16.3个月后存活。他们的平均相加欧洲心脏手术风险评估系统（EuroSCORE）为6.5±3.2。远端吻合的平均数量为2.5±0.5。6例移植吻合至右冠状动脉，2例至左前降支动脉，3例至回旋支动脉。所有11例牛移植在14.1±3.6个月后均被发现闭塞。这表明牛冠状动脉移植的结果非常差，因此我们不建议使用，并建议在特定病例中考虑采用混合方法。
