[Right main bronchus tumoral obstruction during left pneumonectomy].

We report a case of severe airway obstruction during a pneumonectomy, due to a tumor embolus in the contralateral main bronchus. Trachea was intubated with a single-lumen tube with a bronchial blocker. This kind of accident is very rare, and often fatal. The mass was retrieved by rigid bronchoscopy and the patient made an uneventful recovery.
