Abstract

Morel-Lavallée lesions (MLL) create pre-fascial space by shearing the subcutaneous tissues away from the underlying fascia, in a patient with trauma. Necrosis of the overlying skin can develop over a wide area of the lesion. The lesion might be contaminated by the surgical site due to careless intrusion when treating the combined arteriopathy. A 70-year-old woman presented with avulsion of the skin over the right foot and bilateral leg pain following a car accident. Computed tomography showed bilateral popliteal artery occlusion with large hematoma on both legs. Percutaneous angioplasty was performed with successful restoration of the flow. However, the skin color changes over time. Necrosis of the skin occurred over a wide area of the right leg. Extensive debridement was performed, and the defect was covered with a skin graft. MLLs can occur in patients with multiple traumas, multiple vascular injuries, and complex skeletal injury. Vascular surgeons treating multiple traumas should be aware of the diagnostic and management options for MLL. It should be diagnosed early because it can be difficult to manage once the overlying skin develops necrosis.
