Saphenous vein was the conduit used in the first series of coronary artery bypass grafting (CABG), and, with the exception of surgical revascularization of the left anterior descending artery, it remains the most commonly used bypass conduit. However, its durability and longevity are not ideal. Arterial grafts have better patency than saphenous vein grafts and therefore should be preferred over them. However, in certain situations, like grafting right coronary arteries with lesser degree of proximal stenosis and higher competitive flow, or in certain patient populations, like those at very high risk of wound infections and octogenarians, arterial grafting may not be the best option and saphenous vein grafting should be considered instead.
大隐静脉是首批冠状动脉旁路移植术（CABG）中使用的血管 conduit，并且，除了左前降支动脉的外科血运重建外，它仍然是最常用的旁路血管 conduit。然而，其耐用性和寿命并不理想。动脉移植物的通畅率优于大隐静脉移植物，因此应优先于大隐静脉移植物使用。然而，在某些情况下，如近端狭窄程度较轻且竞争血流较高的右冠状动脉移植，或在某些患者群体中，如伤口感染风险非常高的患者和八旬老人，动脉移植可能不是最佳选择，而应考虑大隐静脉移植。 （注：原文中“conduit”未明确准确意思，这里保留英文未翻译）
