- Abstract: Objective To investigate the clinical effect of posterior femoral composite tissue flap pedicled with inferior gluteal artery for repair of huge sacrococcygeal pressure injuries.Methods The clinical data of 11 patients with huge sacrococcygeal pressure injuries admitted to our hospital were retrospectively analyzed,with a mean wounds area of(205.3±15.3)cm2,and the depth of the wounds all reached the sacrococcygeal bone surface with partial sacrococcygeal necrosis.The inferior gluteal artery and its perforating branch were investigated with ultrasonic Doppler flow detector before operation,the posterior femoral composite tissue flap pedicled with inferior gluteal artery was designed according to the wound surface,and then the chronic sacrococcygeal wound was repaired.The operation time,intraoperative blood loss,wound healing,postoperative skin flap survival and occurrence of complications were recorded.The skin flap color,temperature and two-point discernability were monitored to evaluate skin flap sensory sensitivity.The visual analog scale(VAS)was used to evaluate the satisfaction of appearance.Results The operation time of patients was(2.8±0.1)hours and the intraoperative blood loss was(235.4±10.2)mL.The posterior femoral composite tissue flap pedicled with inferior gluteal artery of all the 11 patients survived.The distal part of the flap was necrotic in 1 case,which healed well after local debridement and suturing by amplification;other wounds healed well in the first stage without complications such as infection,fat liquefaction or hematoma.The skin flap has good color,soft texture,and good elasticity,with good healing in the donor area.There were significant differences in the skin flap temperature,two-point discernability and VAS score of appearance satisfaction between 12 months after operation and other time points(P＜0.05).Conclusion The posterior femoral composite tissue flap pedicled with inferior gluteal artery has a constant blood supply,without damage to the main blood vessels.It can be transposed at anterograde or retrograde direction,with simple operation and less damage,which can reconstruct flap sense,and has significant clinical efficacy in repairing huge sacrococcygeal pressure injuries.
