Abstract

Percutaneous pleural maneuvers are performed routinely in the management of pleural diseases with a favorable safety profile. We report a case of cerebral air embolism during a pleural lavage for the management of an empyema. This severe complication is rarely reported in the literature, although it can happen after any percutaneous thoracic procedures. Asymptomatic arterial air emboli can occur in up to 5% of percutaneous thoracic maneuvers. Diagnosis should be made upon sudden neurologic signs and confirmed with brain imaging. Standard treatment is based on hyperbaric oxygen therapy, and it can be performed safely with an intrapleural catheter.
