[Anesthesia for tracheal metal stent management utilizing venovenous extracorporeal life support].

We report a successful case of metal stent replacement utilizing venovenous extracorporeal life support (VV-ECLS). A 71-year-old woman, who had previously undergone tracheal metal stent placement, encountered dyspnea associated with inversion of the stent. Metal stent replacement was planned under general anesthesia. After securing the VV-ECLS in the right and left femoral vein, anesthesia was induced with propofol and remifentanil. Metal stent replacement was conducted under rigid and flexible bronchoscope through the tracheal tube. Oxygenation and carbon dioxide excretion were achieved uneventfully. VV-ECLS was considered useful for the management of subglottic difficult airway such as complex tracheal stenosis.
