ABSTRACT
Objective:To investigate the clinical effects of perforator flaps in the repair of limb defects.Methods:Anterolateral thigh perforator flap (ALTP), deep inferior epigastric perforator flap (DIEP), posterior in- terosseous artery perforator flap (PIAP), thoracodorsal artery perforator flap (TDAP), medial sural artery perforator flap (MSAP) and radial collateral artery perforator flap (RCAP) were used to repair 56 cases of limb wounds from Novem- ber, 2016 to October, 2018. The sizes of soft tissue defect were ranged from 1.5 cm×1.5 cm to 10.0 cm×24.0 cm, while the sizes of flap were ranged from 2.0 cm×2.0 cm to 11.0 cm×25.0 cm. The recipient sites were all sutured di- rectly. The flaps survived and wound healing were observed postoperatively. Appearance, texture, recovery of the limb function, shape and function of donor site were followed-up regularly.Results:One case of venous crisis occurred on the 3rd day after inferior epigastric artery perforator flap surgery, and survived after exploratory surgery with the necrosis in the distal part of the flap, which healed after dressing. Other 55 flaps all survived. Both recipient site and donor site healed in primary union. The color of the flaps was normal. The skins were soft, and the functions of the limbs recovered well. Only a linear scar remained in the donor area without dysfunction.Conclusion:The perforator flap surgery is reliable for limbs repair and can be promoted and applied.
