Purpose: Soft tissue defects in the lumbosacral area can be challenging to treat, and various methods to accomplish this have been proposed, including the use of perforator flaps. Herein, we present our experience with superior gluteal artery perforator (SGAP) and inferior gluteal artery perforator (IGAP) flaps for the reconstruction of lumbosacral defects.
Materials and Methods:
From March 2013 to July 2016, 28 cases (27 patients) of lumbosacral defects were treated by reconstruction with SGAP or IGAP flaps. The defects were caused by pressure sores (21 cases), burns (3 cases), tumor resection (2 cases), scars (1 case), or foreign body infection (1 case). Reliable perforators around the defect were found using Doppler ultrasound. The perforator flaps were elevated with a pulsatile perforator and rotated to cover the defects.
Results: Twenty-three SGAP and 5 IGAP flap reconstructions were performed. The mean flap size was 9.2×6.1 cm2 (range, 5×3 cm2 to 16×10 cm2). Donor sites were closed by primary closure. Partial flap necrosis occurred in two cases, and minor complications of wound dehiscence occurred in 3 cases, which were healed by primary closure. The mean follow-up period was 4.4 months (range, 1~24 months).
Conclusion: Gluteal-based perforator flaps can be safely harvested due to pliability and reliable vascularity in the gluteal area, reducing donor site morbidity without sacrificing the underlying muscles. Thus, these flaps are useful options for the reconstruction of lumbosacral defects.
