Abstract: Objective To analyze the influencing factors for the graft patency of radial artery(RA)after coronary artery bypass grafting(CABG). Methods Clinical data of 65 patients who adopted RA grafts in isolated CABG and underwent computed tomography angiography one year after operation were retrospectively analyzed, including preoperative, intraoperative and postoperative data. Multiple logistic regression analysis was performed to explore the influencing factors for RA graft patency. Results Native stenosis of target vessel ≥80%(OR=0.212, 95%CI: 0.049-0.912, P=0.037), and target vessel in the left anterior descending artery territory(OR=0.104, 95%CI: 0.012-0.921, P=0.042)were independent protective factors for RA graft patency, while non-adherence to the postoperative combination of anti-spastic medications(OR=6.825, 95%CI: 1.857-25.083, P=0.004)was an independent risk factor. Conclusion Proper choice of target vessels during the operation and combination of anti-spastic medications after operation are independent influencing factors for RA graft patency.
