Paradoxical Air Embolism during Percutaneous Nephrolithotomy: A Case Report

Abstract

Air embolism is a rare complication of percutaneous nephrolithotomy. Patent foramen ovale, which is necessary in fetal circulation, is a potential route for emboli arising from the venous system to enter the systemic arterial circulation, resulting in paradoxical air embolism syndrome. A case of paradoxical air embolism during percutaneous nephrolithotomy is presented. To our knowledge, this is the first report of paradoxical air embolism associated with patent foramen ovale during percutaneous nephrolithotomy.
