Two cases of air bubble in intracardiac cavity after computed tomography-guided lung puncture

Abstract

Increasing numbers of peripheral and small lung tumors are being detected, and cases of computed tomography (CT)-guided lung puncture, for example, needle biopsy and marking, are growing. Air embolism is a rare but critical complication of CT-guided lung puncture. We report two cases of an air bubble in the intracardiac cavity after CT-guided lung puncture, which disappeared after about 60 minutes of posture control. We suggest that CT-guided lung puncture should be carried out carefully with the appropriate selection of cases.
