Reconstruction of a high-energy penetrating injury from the abdomen to the sacral area using a latissimus dorsi free flap with monofilament polypropylene mesh and pedicled flap rotation

A 50-year-old man was transferred to a level I trauma center for penetrating injury. Industrial metal had penetrated his trunk, and he was injured in internal organs. The injured internal organs were treated by the trauma surgery team. The peritoneum was reconstructed with artificial dermal matrix graft. The wound was managed with negative-pressure wound therapy, and several debridement procedures were performed. The full-thickness abdominal defect was covered with monofilament polypropylene mesh(Parietene mesh, 30×30 cm). A latissimus dorsi flap was elevated with a musculocutaneous flap measured 50×30 cm, and 6-cm thoracodorsal artery pedicle. Microvascular anastomosis was performed using the thoracodorsal and left femoral arteries. Two weeks later, we performed local flap rotation based on gluteal artery perforator in the sacral area. Polypropylene mesh was successfully inserted without complications. Combining a latissimus dorsi free flap on a polypropylene mesh can be an effective method for reconstructing large penetrating wounds on the trunk.
