Venous air embolism.

R E Kinard, J E Williams, W W Orrison

    Southern Medical Journal
    |January 1, 1987
    PubMed
    Summary
    This summary is machine-generated.

    A new sign on chest X-rays, an air-fluid level in the pulmonary artery, indicates venous air embolism. This finding is definitive when the patient is upright during imaging.

    Area of Science:

    • Radiology
    • Cardiopulmonary Imaging
    • Vascular Radiology

    Background:

    • Venous air embolism (VAE) is a rare but potentially fatal complication.
    • Diagnosis of VAE often relies on clinical suspicion and imaging findings.
    • Standard imaging modalities may not always reveal subtle signs of VAE.

    Observation:

    • This case report details a novel radiologic observation.
    • An air-fluid level was identified within the pulmonary artery on a chest radiograph.
    • The patient's chest film was obtained in the upright position.

    Findings:

    • The presence of an air-fluid level in the pulmonary artery is a newly described radiologic finding.
    • This specific finding is pathognomonic for venous air embolism.

    Related Experiment Videos

  • The diagnostic utility is confirmed when the chest film is performed in the upright position.

    • Implications:

    • This finding offers a highly specific diagnostic marker for VAE.
    • It may aid in earlier and more accurate diagnosis of venous air embolism.
    • Radiologists and clinicians should be aware of this sign for improved patient management.
