| 摘 要： | Objective To compare the long-term patency and longevity of the single and sequential ve-nous graft. Methods The coronary arterial angiographic data for 300 redo coronary bypass grafting (CABG) were collected. Among them 106 cases had both single (159) and sequential (118) grafts. Results The oc-clusive and narrowness rate for the single grafts versus sequential grafts were: 1 year, 2% vs 2% ; 5 years, 3% vs 4% ; 10 years, 18% vs 19% ; 15 years, 60% vs 68% ; and 23 years, 76% vs 81% , respectively. The differences were not significant in general. Conclusion Sequential anastomosis itself does not has any adverse affects on short-term and long-term patency of the venous graft and its longevity in CABG operations in general.
