Randomized trials show high long-term patency for no-touch saphenous vein grafts in coronary artery bypass grafting. The patency rate in off-pump coronary bypass surgery for these grafts has not been investigated. Our center participated in the CORONARY randomized trial, NCT00463294. This is a study aimed to assess the patency of no-touch saphenous veins in on- versus off-pump coronary bypass surgery at five-year follow-up.

非体外循环和非体外循环冠状动脉旁路移植术中无接触大隐静脉和左胸内动脉的五年通畅

随机试验表明，在冠状动脉旁路移植术中，非接触式大隐静脉移植物的长期通畅率很高。尚未研究这些移植物在非体外循环冠状动脉搭桥手术中的通畅率。我们中心参加了冠状动脉随机试验，NCT00463294。这是一项旨在评估非体外循环冠状动脉搭桥手术与非体外循环冠状动脉搭桥手术中非接触式大隐静脉通畅情况的研究，为期 5 年的随访。
