Patient Characteristics and Operative Data
The study patients who had occluded SV conduits and were reevaluated by 1-year angiographies included 37 men and 9 women with a mean age of 65.9±10.7 years. When we compared group R with group O, there were no differences in demographic data and preoperative risk factors between the 2 groups (Table 1). The median number of distal anastomoses per patient was 4.0 [3, 4] and the median number of distal anastomoses per SV conduit was 3.0 [2.0, 3.8]. The percentage of SV harvested with pedicle tissue was higher in group R than in group O, with marginal significance (64.3% [9/14] versus 31.2% [10/32]; P =0.077). However, there were no differences in other operative data, including the median number of distal anastomoses per patient, median number of anastomoses per SV conduit, and percentages of SV anastomosed to each coronary artery territory, between the 2 groups (Table 2).
