背景资料：2004年，一项前瞻性随机试验表明，3年后，采用非接触（NT）技术采集的隐静脉（SV）比用于冠状动脉搭桥手术的桡动脉移植物具有更大的通畅性。方法：对108例冠状动脉旁路移植术（CABG）患者进行8年随访。每例患者被分配接受1个NT SV和1个桡动脉（RA）移植到左或右冠状动脉区域，以补充左胸廓内动脉（LITA）。顺序移植是常见的，所以整体移植通畅性以及通畅性的每个anasthesis.Results：血管造影进行了84例（78%），平均97个月后。NT和RA的移植物通畅率较高且相似：NT为86%，RA为79%（P = 0.22）。NT SV移植物的冠状动脉狭窄通畅率显著更高（91% vs 81%; P = 0.046）。NT移植物在冠状动脉中也具有良好的通畅性，
Background: In 2004, a prospective randomized trial demonstrated that after 3 years, saphenous veins (SVs) harvested with a no touch (NT) technique had a greater patency than radial grafts for coronary bypass surgery. Here we report the 8-year follow-up data of this trial.Methods: The trial included 108 patients undergoing coronary artery bypass grafting (CABG). Each patient was assigned to receive 1 NT SV and 1 radial artery (RA) graft to either the left or right coronary territory to complement the left internal thoracic artery (LITA). Sequential grafting was common, so overall graft patency as well as the patency of each anastomosis were assessed.Results: Angiography was performed in 84 patients (78%) at mean of 97 months postoperatively. Graft patency were high and similar for both NT and RA: 86% for NT versus 79% for RA (P = .22). The patency of coronary anastomoses was significantly higher with the NT SV grafts (91% vs 81%; P = .046). The NT grafts also had excellent patency in coronary arteries with
