Poor long-term patency of saphenous vein grafts limits the long-term success of the coronary artery bypass operation. If this is to be improved, either measures that increase the patency of saphenous vein grafts or alternative conduits are required. The benefits of using the left internal mammary artery as a pedicled graft to the left anterior descending coronary artery have prompted increasing use of arterial grafts to further improve outcome. Concurrently advances in the understanding of the pathological processes underlying saphenous vein graft occlusion raise the possibility of improving vein graft patency. In this paper we review the problem of vein graft occlusion and possible solutions, the theoretical benefits of arterial grafts and the clinical results associated with their use.
大隐静脉移植物的远期通畅率不佳限制了冠状动脉旁路移植术的长期成功率。若要改善这一情况，要么采取措施提高大隐静脉移植物的通畅率，要么使用替代血管。将左乳内动脉作为带蒂移植物移植至左前降支冠状动脉所带来的益处，促使人们越来越多地使用动脉移植物以进一步改善手术效果。与此同时，对大隐静脉移植物闭塞潜在病理过程认识的进展，增加了改善静脉移植物通畅率的可能性。在本文中，我们综述了静脉移植物闭塞问题及可能的解决方法、动脉移植物的理论益处以及使用动脉移植物的临床结果。
