Vacuum Sealing Drainage Combined with Retrograde Saphenous Neurocutaneous Flap Transplantation in the Treatment of Diabetic Foot Ulcer Wounds
Objective To analyze the efficacy of vacuum sealing drainage(VSD)combined with retrograde saphenous neurocutaneous flap transplantation in treating diabetic foot ulcer(DFU)wounds.Methods A retrospective analysis was conducted on 92 patients with DFU admitted to the author's hospital from July 2020 to March 2023.According to different treatment methods,they were grouped into a flap transplantation group(47 cases)and an observation group(45 cases).The skin flap transplantation group carried out retrograde saphenous neurocutaneous flap transplantation,while the observation group combined VSD on the basis of the skin flap transplantation group.The changes in ulcer area,wound recovery,pain improvement time,incidence of complications,and amputation status of the patient were statistically compared between the two groups.Results The ulcer area of the two groups decreased obviously at 2 and 4 weeks after surgery compared to before surgery(P＜0.05),and the reduction in the observation group was more obvious than that in the flap transplantation group(P＜0.05).The total effective rate of the observation group(87.23%)was obviously higher than that of the flap transplantation group(64.44%)(P＜0.05).The wound healing time,pain improvement time,and limb sensation recovery time of the observation group were obviously shorter than those of the skin flap transplantation group(P＜0.05).The incidence of complications in the observation group(2.13%)was obviously lower than that in the flap transplantation group(17.78%)(P＜0.05),and there was no statistically obvious difference in amputation rate(4.26%)compared to the flap transplantation group(13.33%)(P＞0.05).Conclusion The combination of VSD and retrograde saphenous neurocutaneous flap transplantation for DFU patients can promote wound healing,improve pain,and restore limb sensation,reduce complications such as flap necrosis,and to some extent reduce the risk of amputation.
