Bilateral internal mammary artery (BIMA) grafts are used for coronary revascularisation by only a minority of surgeons, despite a growing body of evidence suggesting improved survival when compared to use of only one internal mammary artery with additional saphenous vein grafts. Herein we review the evidence supporting revascularisation with BIMA and suggest reasons why the majority of surgeons use only one internal mammary artery. We discuss technical considerations, various graft combinations and the use of BIMA to facilitate anaortic off-pump coronary artery bypass (OPCAB).
双侧内乳动脉(BIMA)移植仅被少数外科医生用于冠状动脉血运重建,尽管越来越多的证据表明,与仅使用一根内乳动脉加隐静脉移植相比,这种方法可提高生存率。本文综述了支持使用 BIMA 进行血运重建的证据,并提出了大多数外科医生仅使用一根内乳动脉的原因。我们讨论了技术考虑因素、各种移植组合以及使用 BIMA 来促进非体外循环冠状动脉旁路移植术(OPCAB)。
