The superior long-term patency and survival of the internal thoracic artery in coronary artery bypass grafting, compared with saphenous vein, established the internal thoracic artery as the conduit of choice for myocardial revascularization. Use of the internal thoracic artery has expanded, and the possibility of similar performance by other arteries has motivated surgeons to investigate alternative arterial conduits (eg, the gastroepiploic artery, inferior epigastric artery, and radial artery). Although these grafts have become more technically feasible and have shown benefits, more follow-up data are needed to determine the long-term patency, freedom from arteriosclerosis, and efficacy of alternative conduits.
与隐静脉相比，胸廓内动脉在冠状动脉旁路移植术中具有更好的长期通畅率和生存率，这使得胸廓内动脉成为心肌血运重建的首选管道。胸廓内动脉的应用范围不断扩大，其他动脉可能具有类似性能这一可能性促使外科医生研究替代动脉管道（如胃网膜动脉、腹壁下动脉和桡动脉）。尽管这些移植物在技术上已变得更可行且已显示出益处，但仍需要更多的随访数据来确定替代管道的长期通畅率、无动脉硬化情况及疗效。
