Background
Venous air embolism (VAE) is a well-known entity in the field of neuroanesthesia, with established surgeries and positions where its occurrence is high. The insular cortex is a deep area within the lateral sulcus, and surgeries in this area are not reported to develop VAE.
Case presentation
A young male being operated on the insular cortex developed VAE, had cardiac arrest, was revived, and was extubated with no residual deficit due to the untoward event.
Conclusions
An anesthesiologist should always be prepared for this complication due to its rapid presentation and fatal consequences.
