The radial artery (RA) can be used as part of an arterial revascularization strategy in coronary artery bypass grafting (CABG). It is easy to harvest and several randomized controlled trials and meta-analyses have reported superior long-term patency over saphenous vein grafts. However, the RA is not used as frequently as the saphenous vein and questions remain regarding its optimum use as a conduit. This article comprehensively appraises current evidence surrounding outcomes, patient selection, harvesting technique, intraoperative strategy, and graft spasm prophylaxis to provide a contemporary review of the use of the RA as a conduit in CABG.
桡动脉（RA）可作为冠状动脉旁路移植术（CABG）中动脉再血管化策略的一部分。它易于采集，多项随机对照试验和荟萃分析报告称，其长期通畅率优于隐静脉移植物。然而，RA 的使用频率不如隐静脉高，关于其作为移植物的最佳使用仍存在疑问。本文全面评估了与结果、患者选择、采集技术、术中策略和移植物痉挛预防相关的现有证据，为 CABG 中 RA 作为移植物的使用提供了当代综述。
