Left ventricle and systemic air embolism after percutaneous lung biopsy.

BACKGROUND

Systemic arterial air embolism following a percutaneous transthoracic lung biopsy is a rare but known complication, with current literature reporting an incidence of 0.01-0.45%. A prompt diagnosis of arterial air embolism is important as complications resulting from migration of air to the systemic circulation with correspondent complications.

CASE REPORT

A 60-year-old female who presented for an elective percutaneous lung biopsy of an incidentally found pulmonary nodule. The procedure was performed, following the completion of the procedure the patient experiment syncopal symptoms and was diagnosed by CT scan with Left ventricular air embolism, subsequently transferred to Intensive care unit for medical attention, she was placed on right lateral decubitus Trendelenburg for 24 hours and administer 100% oxygen via a nonrebreather mask. Repeat chest CT the following day revealed complete resolution of her intracardiac free air.

CONCLUSION

Although systemic arterial air embolism remains a rare complication of percutaneous lung biopsies, recognition prevents potential mortality which can develop due to neurological and cardiac complications. Close vigilance in the intensive care unit is recommended and hyperbaric chamber when appropriate.
