Anesthetic Experience of Patients with a Congenital Tracheal Bronchus: A report of two cases / 대한마취과학회지

ABSTRACT

A tracheal bronchus is an aberrant, accessory or ectopic bronchus arising almost always from the right lateral wall of the trachea at the level less than 2 cm above the carina. An endotracheal or endobronchial tube can obstruct or migrate into a tracheal bronchus, resulting in pulmonary atelectasis, hypoxemia, or both during general anesthesia. We report two patients in whom the anomalous tracheal bronchus had been surgically resected under general anesthesia. The anomaly was identified before surgery in each patient and anesthesia was uneventful.
