Iatrogenic venous air embolism during contrast enhanced computed tomography: a report of two cases.

Venous air embolism (VAE) is a known complication of venous access procedures such as contrast-enhanced computed tomography (CECT). Although a massive VAE can be fatal, most iatrogenic VAE cases during CECT involve a few milliliters of air and are asymptomatic. We report two cases of massive and nonfatal VAE during CECT.
