Reconstruction for Severe Extracorporeal Membrane Oxygenation-induced Ischemic Lower Limb Injury Complicated by Osteomyelitis.

Abstract

Summary: Extracorporeal membrane oxygenation (ECMO) is a well-established mechanical circulatory support system used in patients with life-threatening cardiopulmonary conditions. However, severe complications associated with vascular access require consideration. We report a patient with fatal ventricular arrhythmia who was successfully resuscitated with ECMO but who developed severe lower limb ischemia, which resulted in compartment syndrome. Even with emergent fasciotomy, tissue necrosis developed in wide areas of the limb, with subsequent tibial osteomyelitis. After extensive debridement and tibial sequestrectomy, the soft tissue and bone defect were simultaneously reconstructed with free tissue transfer of the latissimus dorsi muscle and scapular tip composite flap. The limb was successfully salvaged with satisfactory functional outcomes without major complications. This report discusses limb reconstruction for ECMO-induced compartment syndrome and illustrates the importance of appropriate selection of reconstruction methods among various composite flaps.
