    Abstract:
    Percutaneous tracheostomy (PT) has become popular recently, but occasionally cannula exchange can be difficult and hazardous. A 55-year-old woman with pontine hemorrhage was admitted to our ICU after oral intubation. On the 3 rd day, PT was performed with no complication to prepare for prolonged airway management. On the 14 th day, surgical removal of the pontine hematoma was scheduled. Since our neurosurgeon requested a prone position with maximal neck anteflexion, she was re-intubated orally and the tracheostomy cannula was removed during the operation. At the end of the operation, the tracheostoma had already been narrowed and re-insertion of a narrower tracheostomy cannula was unsuccessful even with bronchoscopic guidance. Following several attempts, her Spo2 gradually decreased and her blood pressure dropped. A chest X-ray showed right pneumothorax and a chest drainage tube was inserted. Posterior tracheal wall injury was suspected, though the exact injury site was not identified bronchoscopically. She was treated conservatively because no air leak was observed after advancing the oral tube. Three weeks later, surgical tracheostomy was performed without major abnormal findings. A small tracheostoma characteristic of PT might be associated with an increased risk of delayed airway complication. Cannula exchange should be performed more carefully after PT compared with surgical tracheostomy.
