Abstract:
BACKGROUND: We analysed the characteristics of anastomotic sites after coronary artery bypass grafting (CABG) using coronary angiographies (CAGs) performed at one and five years postoperatively in the same patient population. MATERIAL AND METHOD: Among the 219 patients who underwent isolated CABGs between January 1995 and December 1997, follow-up coronary angiograms were performed in 149 (75.3%) patients at one year and in 115 (58.1%) patients at five years postoperatively. FitzGibbon grading system was used to evaluate the anastomotic sites. RESULT: The patency rates of arterial grafts at one- and five-year were 96.5% (192/199) and 93.1% (134/144), which were higher than those of saphenous vein grafts (SVGs) (82.9% (224/270) and 77.5% (141/182), respectively) (p=0.01). Although there were significant decreases in the patency rates between one- and five-year CAGs of both arterial and venous grafts, the proportion of FitzGibbon grade B among the SVGs was increased from 5.2% (one-year) to 8.2% (five-year), suggesting the progression of vein graft disease (p<0.01). CONCLUSION: The patency rate of the arterial graft was higher than that of SVG in both one- and five-year CAGs. The attrition rate of saphenous vein graft was higher than arterial grafts.
