Flow-controlled One-lung Ventilation During Carinal Sleeve Reconstruction: Anaesthetic Management and Technical Feasibility

ventilator and maintained throughout airway reconstruction. Ventilation was achieved without interruptions, apneic periods, or cross-field ventilation. Oxygenation and carbon dioxide elimination remained stable during 180 minutes of FCV, while the small-lumen tube provided optimal surgical exposure. The patient was extubated uneventfully at the end of surgery and experienced an uncomplicated postoperative course. This case highlights the feasibility of flow-controlled OLV as an anaesthetic strategy during complex airway reconstruction. FCV-OLV enabled uninterrupted ventilation, stable gas exchange, and excellent surgical conditions without the need for extracorporeal support or alternative ventilation techniques.
