Systemic Air Embolism Detected During Percutaneous Transthoracic Needle Biopsy: Report of Two Cases and a Proposal for a Routine Postprocedure Computed Tomography Scan of the Aorto-cardiac Region

Systemic air embolism is a rare but potentially fatal complication of percutaneous transthoracic biopsy. Herein, we report two cases of nonfatal air embolism that occurred during a computed tomography (CT)-guided lung biopsy. It can be concluded that postprocedure CT scans of the aorto-cardiac region and attention focused on systemic air on CT scan images during biopsy procedures can be helpful for early recognition of the complication, a step that is important for successful treatment.
