ABSTRACT
BACKGROUND: Soft coagulation is widely used for hemostasis because of its significant advantage in inducing tissue coagulation and denaturation without carbonization. However, a few cases of airway damage have been reported at the site, where soft coagulation was directly applied. CASE PRESENTATION: We encountered an unusual case of delayed perforation of the intermediate bronchial trunk observed on 24 days after cauterization of the right S6 bulla adjacent to the bronchus. Chest computed tomography revealed a large fistula between the intermediate bronchial trunk and the cauterized bulla in the right S6. Bronchoscopy showed a large fistula at the membranous portion of the intermediate bronchial trunk. We presumed that the bronchial perforation resulted from thermal damage to the intermediate bronchial trunk during bulla cauterization and the bronchial perforation induced infection in the bulla. Resection of the infectious bulla and the intermediate bronchial trunk, followed by end-to-end bronchial anastomosis and a pedicled intercostal muscle flap coverage, was performed. CONCLUSIONS: The severe airway damage resulting in perforation developed even without direct contact between the electrode tip and the bronchial wall, provoking the need for special attention to the duration of cauterization and location, where it is used.
ABSTRACT
Bronchial injury is a rare and serious complication of endotracheal intubation in neonates. Bronchial perforation following tracheal intubation causes a high-volume air leak mimicking pneumothorax and pneumomediastinum, and it may result in intraventricular hemorrhage, mediastinitis and sepsis. I report my experience of diagnosing a main bronchial perforation in an extremely low birth weight infant, who had a high-volume air leak following tracheal intubation, which persisted after chest tube insertion.
