Table 1. Results of blood flow measurements after surgery^▲.

Groups	Day 1	Day 3	Day 5	Day 7
Control group (Arterial perfusion group)	57.00 ± 1.41	61.33 ± 0.81	62.00 ± 1.41	62.50 ± 1.87
Experimental group I (inflow:outflow,1:1)	27.83 ± 1.17	33.50 ± 1.05	33.00 ± 0.89	33.17 ± 4.87
Experimental group II (inflow:outflow,1:2)	39.33 ± 1.37	44.50 ± 1.87	42.83 ± 0.98	42.00 ± 1.09
Experimental group III (inflow:outflow,1:3)	38.83 ± 1.72	44.83 ± 1.60	44.17 ± 1.47	43.50 ± 1.38

^▲Of all the observed time points, the blood perfusion units of the control group were all significantly different from the three experimental groups (all p < 0.001) and those of the experimental group I were also significantly different from the other two experimental groups (all p < 0.01); however, no significant differences were noted between the experimental group II and III (all p > 0.05).
