Tracheobronchial stenting in an infant with an anomalous right main bronchus.
Congenital anomalies of the right main bronchi have not been fully described. Bronchial anomalies are usually asymptomatic unless they coexist with other abnormalities. We describe a rare bronchial anomaly in a 2-month-old girl in which the right upper lobe, middle lobe, and lower lobe bronchi all originated at the same point as a result of a developmental teratogenic long right main bronchus and an absent bronchus intermedius. Furthermore, the left main bronchus contained a proximal segment of stenosis. This combination of anomalies, along with right upper lobe atelectasis and left-sided hyperinflation, resulted in a severe right mediastinal shift and respiratory distress. The mediastinum was returned to midline with endoscopic placement of an in-dwelling tracheobronchial stent into the left main bronchus. To the best of our knowledge, the specific developmental anomaly in our patient has not been previously described.
