Retroperitoneal air dissection associated with mechanical ventilation.

D J Powner, J V Snyder, C W Morris

    Chest
    |June 1, 1976
    PubMed
    Summary

    Pulmonary air dissection into the retroperitoneal space can occur in mechanically ventilated patients. This condition, linked to airway pressures and lung disease, may cause serious respiratory and circulatory issues.

    Area of Science:

    • Radiology
    • Pulmonology
    • Critical Care Medicine

    Background:

    • Mechanical ventilation can lead to airway disruption.
    • Retroperitoneal space is an uncommon site for pulmonary gas dissection.

    Observation:

    • Reviewed three patients with mechanical ventilation who developed gas dissection into the retroperitoneal space.
    • Observed relationship between peak airway pressures, underlying pulmonary disease, hemodynamic status, and airway disruption.
    • Noted interstitial emphysema and air embolization as potential consequences.

    Findings:

    • Gas dissection into the retroperitoneal space originates from pulmonary sources.
    • This phenomenon can result in interstitial emphysema and air embolization.
    • Severe respiratory or circulatory dysfunction may arise from these complications.

    Implications:

    • Retroperitoneal gas dissection requires consideration in the differential diagnosis of free intra-abdominal gas.
    • Understanding the etiology and radiologic patterns aids in managing ventilated patients.
    • Early recognition can prevent severe cardiorespiratory complications.
