title: A reusable perforator-preserving gluteal artery-based rotation fasciocutaneous flap for pressure sore reconstruction.
abstract: BACKGROUND
  Perforator-based fasciocutaneous flaps for reconstructing pressure sores can achieve good functional results with acceptable donor site complications in the short-term. Recurrence is a difficult issue and a major concern in plastic surgery. In this study, we introduce a reusable perforator-preserving gluteal artery-based rotation flap for reconstruction of pressure sores, which can be also elevated from the same incision to accommodate pressure sore recurrence.
  
  
  METHODS
  The study included 23 men and 13 women with a mean age of 59.3 (range 24-89) years. There were 24 sacral ulcers, 11 ischial ulcers, and one trochanteric ulcer. The defects ranged in size from 4 × 3 to 12 × 10 cm(2) . Thirty-six consecutive pressure sore patients underwent gluteal artery-based rotation flap reconstruction. An inferior gluteal artery-based rotation fasciocutaneous flap was raised, and the superior gluteal artery perforator was preserved in sacral sores; alternatively, a superior gluteal artery-based rotation fasciocutaneous flap was elevated, and the inferior gluteal artery perforator was identified and dissected in ischial ulcers.
  
  
  RESULTS
  The mean follow-up was 20.8 (range 0-30) months in this study. Complications included four cases of tip necrosis, three wound dehiscences, two recurrences reusing the same flap for pressure sore reconstruction, one seroma, and one patient who died on the fourth postoperative day. The complication rate was 20.8% for sacral ulcers, 54.5% for ischial wounds, and none for trochanteric ulcer. After secondary repair and reconstruction of the compromised wounds, all of the wounds healed uneventfully.
  
  
  CONCLUSIONS
  The perforator-preserving gluteal artery-based rotation fasciocutaneous flap is a reliable, reusable flap that provides rich vascularity facilitating wound healing and accommodating the difficulties of pressure sore reconstruction.
