Ilioinguinal Flap Combined With Tensor Fascia Lata Muscle Flap to Repair Deep Electrical Burns in the Lower Abdomen: A Report of Two Cases.

Introduction. Electrical burns are caused by the conversion of electrical energy flowing through the body into heat energy, which can cause coagulative necrosis of the skin and deep tissues. Deep tissue damage is often more serious than skin damage. Electrical burns have the characteristics of destructive and progressive damage and present the common symptoms of severe local tissue damage accompanied by a wide range of deep tissue necrosis, resulting in injury of nerves, blood vessels, bones, and internal organs. Autologous skin grafting alone cannot effectively cover deep tissues or repair electrical burn wounds. Case Report. This article describes 2 patients with deep electrical burns in the lower abdomen that showed extensive skin and soft tissue damage, partial necrosis of abdominal muscle tissue, and weak abdominal wall. As a single tissue flap was too small to effectively cover the defect wound, ilioinguinal flap and tensor fascia lata muscle flap were utilized in both cases with good outcomes. These flaps survived completely, and the wounds were effectively repaired. After repair, the shape was satisfactory, and the function of the lower abdomen was normal. Conclusions. Transfer of flaps from a site near the wound for repairing electrical burns is convenient for transfer with minimal surgical trauma and a simpler operating procedure than the free flap.
