Postoperative anastomosis patency in group A patients

	Inner diameter (mm)	blood flow velocity(cm/s)
1 month postoperatively(n = 24)	1.13 ± 0.22		6.51 ± 4.86
3 month postoperatively (n = 25)	1.22 ± 0.25		8.86 ± 2.47
6 month postoperatively (n = 25)	1.34 ± 0.31		8.95 ± 2.01

Data are presented as mean ± SD. Intragroup comparisons across time points were performed using repeated measures ANOVA with post-hoc tests. One patient who received vascular anastomosis device had the anastomosis site not visible by color Doppler ultrasound at 1-month follow-up due to scar tissue obscuring the view
