Tracheal bronchus: A rare unforeseen anaesthetic challenge

The most common congenital central airway anomaly, a tracheal bronchus is of concern during airway management especially if previously undetected. If present, it can lead to inadequate ventilation both during intubation with a normal endotracheal tube and an attempted double lumen tube insertion for one lung ventilation. Meticulous preoperative assessment and use of adjuncts like bronchoscopy before lung isolation can safely and successfully assist the anaesthetic management of such cases.
