Objective:To compare the effect of stripped perforator pedicle on the survival of perforator flap.Methods:From January, 2015 to December, 2019, 44 patients with soft tissue defects of distal shank and ankle were repaired with perforating vessel pedicled propeller flap. According to the nudity of the perforator pedicle, the patients were divided into 2 groups: stripped group ( n=14) and non-stripped group ( n=30). The gender, age, history of smoking, history of diabetes, location of wound, size of flap, perforator artery of flap, closure method of donor site, degree of flap swelling 3 days after operation, percentage of survival area of flap 7 days after operation and postoperative complications were analysed retrospectively. Data were analyzed statistically. The difference was statistically significant when P<0.05. Results:There was no significant difference between the 2 groups in age, smoking history, diabetes history, wound location, size of flap, perforator artery and donor site closure( P<0.05). The degree of swelling of flap in the stripped group 3 days after operation [(+) 94.00%, (++) 6.00%, (+++) 0.00%, (++++) 0.00%)] was less than that in the non-stripped group [(+)47.00%, (++) 29.00%, (+++) 13.00%, (++++) 11.00%)] . The difference was statistically significant between the 2 groups( P<0.05). The percentage of flap survival area in the stripped group [(100.00±0.00) %] was higher than that in the non-stripped group [(88.23±21.29)%] , and the difference was statistically significant ( P<0.05). The incidence of postoperative complications in the stripped group(0.00%) was lower than that in the non-stripped group (39.00%). The difference heel statistically significant( P<0.05). Conclusion:The stripped pedicle of the perforating vessel can promote a better survival of the arterial perforating branch propeller flap, and the degree of postoperative swelling and complications of the flap are lower.
