CTICasesPulmonary Artery Air Embolism
Imaging findings
Massive air within the SVC and pulmonary artery following an accidental air bolus during CT contrast injection. Pulmonic valve leaflets were clearly visualized due to the air.
Key takeaways
Large air embolisms can cause an "air-lock" phenomenon, abruptly stopping forward blood flow through the lungs. Hyperbaric oxygen therapy may be utilized for management.
