Abstract
A tracheal bronchus is a rare congenital anomaly, suggesting abnormal bronchial development. The prevalence of tracheal bronchus in children who undergo bronchoscopy is estimated to be between 0.2% and 3%. When associated with recurrent infection, lobes of the lung must be removed to avoid further lung injury. In such cases, perioperative one-lung ventilation and airway management remain a huge challenge for anaesthesiologists. The case of this rare airway anatomic abnormality in a paediatric patient with two bronchial openings into the right upper lobe, and with a history of recurrent pneumonia, is reported. In addition to a normal opening, a distinct opening in the upper lobe of the right lung was observed, that originated directly from the trachea, superior to the carina. The entire right lung was deflated by left-lung ventilation using a single lumen tracheal tube, and the patient underwent right upper lobe resection. No anaesthesia complications were observed during recovery. In this case, timely identification of the tracheal bronchus and successful collapse of the right lung were key points in the anaesthesia management of this patient.
