Air embolism complicating computed tomography-guided core needle biopsy of the lung

Computed tomography-guided transthoracic lung biopsy is a common clinical procedure for the diagnosis of a broad range of pulmonary pathological conditions. Mild self-limiting pneumothorax and haemoptysis are common complications of this procedure. Air embolism is a potentially life-threatening but extremely rare complication. We report a case of an air embolism in the left ventricle of the heart that developed after a computed tomography-guided percutaneous needle biopsy of the lung. The patient did not exhibit cardiac or cerebral symptoms after conservative treatment. The patient underwent a successful left thoracotomy with a lobectomy of the left lower lobe of the lung 5 days after the biopsy and recovered uneventfully.
