Abstract：Objective To compare the curative effects between V-Y advancement flap based on perforators and pedicled perforator island in repairing tissue defect of lower limbs.Methods The clinical data of 20 patients with skin and soft defects of lower limbs from September 2019 to December 2022 were analyzed retrospectively.All the patients were divided into group A and group B randomly.The defects were repaired with V-Y advancement flaps based on perforators in group A,while with pedicled perforator island propeller flap in group B.All patients were followed up from 6 months to 12 months after operation.The operative time,intraoperative blood loss,total incision length,flap healing time,flap survival rates and incidence rates of postoperative complications were compared between the two groups.Results The flap survival rate was 100%in group A and 90%in group B.The operative time,intraoperative blood loss,flap healing time and total incision length in group A were shorter than that in group B,and the differences were statistically significant(P<0.05).The incidence rate of postoperative complications was 10%in group A and 100%in group B,with statistically significant differences between the two groups(P<0.005).Conclusions When the soft tissue defect is about 5cm,the V-Y advancement flap was more effective than the pedicle perforator island propeller flap of the lower leg in repairing composite tissue defects of lower limbs.V-Y advancement flap can provide excellent matching texture and a convenient primary closure of the donor site.
