AbstractWe experienced troubled endotracheal intubation in an adult patient with asymptomatic tracheal bronchus. The breath sounds of the right upper lobe were found to be absent right after the placement of a tracheal tube. An anomalous tracheal bronchus (displaced right upper lobar bronchus originating about 1 cm above carina) was found by fiberoptic bronchoscopy. The length of trachea of the patient was about 6 cm shorter than that of the normal value of adult male, which significantly reduced the safe range of positioning a tracheal tube. In a patient with this anomaly, who is otherwise healthy, a placement of a tracheal tube may cause pulmonary complications. Thus, as a diminished breath sound is found to be located at the upper right lobe after endotracheal intubation, we have to think of tracheal bronchus as one of the possible causes.
