ABSTRACT
Computed tomography (CT)-guided percutaneous needle biopsy is a useful method for the diagnosis of lung lesions. We report herein three cases of air embolism following a CT-guided percutaneous needle biopsy in which the clinical course of air movement and eventual resolution of the embolism were able to be observed. In all three cases, the coronary artery air embolism and renal artery air embolism resolved after 40 to 50 minutes of rest without causing any organ damage. Arterial embolisms associated with a CT-guided percutaneous needle biopsy may self-resolve without organ damage. Whenever an air embolism occurs, knowing its clinical course and the appropriate method of intervention is important.
