Abstract

Venous air embolism may occur when the surgical field is above the level of the heart. We present a case of venous air embolism in a patient undergoing percutaneous nephrolithotripsy in the prone position and presenting with blindness and neurological deficits 8 h later. The clinical diagnosis of paradoxical air embolism was confirmed by early single-photon emission tomography (SPET), whereas magnetic resonance imaging including diffusion-weighted imaging (DW-MRI) was diagnostic only 30 h later. Hyperbaric oxygen therapy was successful. In this case, early DW-MRI scan was inconclusive, but a SPET study of the brain appeared to be useful in confirming the clinical diagnosis. Early hyperbaric oxygen was demonstrated to be a successful therapy.
