Arterial grafting for coronary artery disease has been practiced routinely at the Epworth Hospital for 20 years. Bilateral versus single internal thoracic artery grafts is associated with improved survival, which progressively increased over the 20 years of post-surgery. The average increase in survival was 15% at 20 years. The question of whether to use the radial artery or the saphenous vein graft as supplementary grafts remains unanswered. Current patency data suggest that there is a marginal advantage of radial artery over saphenous graft patency, particularly between 5 and 10 years after surgery. However, there appears to be improved patency of the saphenous vein when used as a coronary artery bypass with the advent of aspirin, lipid-lowering and anti-hypertensive therapy.
在爱普沃思医院，冠状动脉疾病的动脉移植手术已常规开展20年。双侧胸廓内动脉移植与单根胸廓内动脉移植相比，患者生存率更高，且在术后20年中这种生存率的提高呈逐渐上升趋势。20年时生存率平均提高了15%。关于是使用桡动脉还是大隐静脉作为补充移植血管的问题仍未得到解答。目前的通畅数据表明，桡动脉在移植血管通畅方面略优于大隐静脉，尤其是在术后5至10年。然而，随着阿司匹林、降脂和抗高血压治疗的出现，大隐静脉作为冠状动脉旁路移植血管时，其通畅情况似乎有所改善。
