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).
