A 16-month-old girl with acute lymphoblastic leukemia expired during Hickman catheter insertion. She had undergone chemoport insertion of the left subclavian vein six months earlier and received five cycles of chemotherapy. Due to malfunction of the chemoport and the consideration of hematopoietic stem cell transplantation, insertion of a Hickmann catheter on the right side and removal of the malfunctioning chemoport were planned under general anesthesia. The surgery was uneventful during catheter insertion, but the patient experienced the sudden onset of pulseless electrical activity just after saline was flushed through the newly inserted catheter. Cardiopulmonary resuscitation was commenced aggressively, but the patient was refractory. Migration of a thrombus generated by the previous central catheter to the pulmonary circulation was suspected, resulting in a pulmonary embolism.
Air embolism is a rare, potentially critical complication that can induce death. Central venous catheterization, which is commonly used for critically ill patients, is a possible cause of air embolism. We experienced a severe air embolism with abnormal air in left ventricle after CVC removal in a patient who was treated for eosinophilic pneumonia. Although the neurologic symptoms were severe, the patient was successfully treated with immediate hyperbaric oxygen therapy and the neurologic deficit was minimal.
