Abstract:
Objective:To explore the clinical effect of application of a posterior femoral perforator flap (PFPF) relayed an adjacent flap of recipient site in reconstruction of the recurrent pressure sores in sacrococcygeal region.Methods:Retrospective observation method was used in this study. From December 2019 to May 2023, 13 patients with recurrent pressure sores in sacrococcygeal region were admitted in the Department of Burns and Plastic Surgery of the 910th Hospital of Joint Service Support Unit of PLA. The patients were 8 males and 5 females who aged 42-69 years old. All the pressure sores were in Grade Ⅲ-Ⅳ. Eight patients had pressure sores for a second time and 5 for a third time. After preoperative preparations, the surgical treatment was planned in 2 stages. In the first stage, the pressure sores were thoroughly debrided, and the wounds after debridement were at 5.0 cm×6.0 cm-15.0 cm×9.0 cm in size. After debridement, the wounds were covered by VSD for 7 days. Flap reconstruction of the wounds of pressure sores were performed in the second stage surgery. According to the location and size of the wounds and the remaining normal skin tissue around the wounds, the adjacent flaps were taken to reconstruct the wounds of sacrococcygeal pressure sore. PFPFs were employed to reconstruct the donor site wounds left by the adjacent flap. The sizes of the adjacent flap were 6.0 cm×7.0 cm-16.0 cm×9.5 cm, and the PFPFs were 9.0 cm×8.0 cm-18.0 cm×10.0 cm in size. PFPF was rotated in a manner of propeller. The donor sites of PFPF were directly sutured. After surgery, survival of the adjacent flaps and PFPFs, the wound healing in the donor sites as well as the healing time were observed. The appearance, texture and recurrence of pressure sores of the flap reconstruction sites were observed at outpatient clinic, via WeChat reviews or telephone interviews up to January 2024.Results:Twenty-six flaps of 13 patients survived after surgery, inclusive of 1 patient with the adjacent flap partially split due to turn-over and transport of the patient after surgery, and healed after a re-suture under local anaesthesia. In addition, 1 patient had effusion under the adjacent flap and 1 patient had partial split under the PFPF, both of which healed after dressing changes, with an overall healing time of 16-30 days. Postoperative follow-ups lasted for 6-12 months. The flaps had good appearance, soft texture, no surface rupture and without the recurrence of a pressure sore.Conclusion:Treatment of recurrent pressure sores in sacrococcygeal region by reconstructive surgery with PFPF relaid adjacent flap can achieve the effects of closure of wound, high survival rate of flap and good wound healing. It does not require skin grafting for the donor site at posterior thigh and achieves a good and long-term therapeutic effects under the circumstance that only a small amount of normal skin tissue is left on the buttocks.
