With increased use of catheter intervention, candidates for coronary artery bypass grafting (CABG) have become more severely diseased. In the past 4 years with normothermic cardiopulmonary bypass technique, operative mortality was 1.5% (0.7% for elective and 5.6% for emergency) in 690 primary CABGs. The internal thoracic artery graft was used in 94% of the patients and the patency rate was 98%. The gastroepiploic artery was used in 565 patients since 1986 with 2.3% operative mortality and the patency rate was 96% in early and 92% in mid-term angiography. The inferior epigastric artery was used in 48 patients with 2% operative mortality and 90% patency rate. The radial artery was used in 105 patients with 0.9% operative mortality and patency rate was 88% at 1 postoperative year. Surgical result and angiographic patency of the graft are acceptably good while candidates of CABG have become more severely diseased. With use of arterial conduits, better long term outcome can be expected.
随着导管介入治疗的使用增加，冠状动脉旁路移植术（CABG）的候选患者病情变得更加严重。在过去4年中，采用常温体外循环技术，690例初次CABG手术的死亡率为1.5%（择期手术为0.7%，急诊手术为5.6%）。94%的患者使用了胸廓内动脉移植物，通畅率为98%。自1986年以来，565例患者使用了胃网膜动脉，手术死亡率为2.3%，早期血管造影通畅率为96%，中期为92%。48例患者使用了腹壁下动脉，手术死亡率为2%，通畅率为90%。105例患者使用了桡动脉，手术死亡率为0.9%，术后1年通畅率为88%。尽管CABG的候选患者病情变得更加严重，但手术结果和移植物的血管造影通畅率仍相当不错。使用动脉移植物有望获得更好的长期效果。
