Abstract

Abstract: Objective To investigate the influence of the pedicled artery position on the survival of multi-territory perforator flap. Methods Thirty-two Sprague-Dawley rats were randomly divided into two groups: a control group, only the right iliolumbar artery and vein were preserved; and an experimental group, only the right iliolumbar vein and the left iliolumbar artery were preserved. At 7 days after operation, the survival of the flap was counted. Arteriography was performed to observe the dilation of the choke arteries, and HE staining microscope was used to measure the intraluminal diameter of the choke artery. Results At 7 days after operation, the survival rate of the flap in the experimental group was significantly higher than that in the control group[ (85.5±2.9)% vs (68.9±2.6)%, P<0.001]. The dilation of the choke1 artery was comparable in both groups [(46.93±6.21) μm vs (46.79±6.69) μm, P>0.05], whereas the choke 2 artery in the experimental group was more dilated than that in the control group[(66.08±6.78) μm vs (46.00±6.90) μm, P<0.001]. Conclusions The position change of the pedicled artery can promote the dilation of the choke artery and the blood supply to the distal part of the flap, so as to increase the survival rate of multi-territory perforator flap.
