Obstructive emphysema due to mucus plugging in quadriplegia.

J R Cohn, R M Steiner, E Posuniak

    Archives of Physical Medicine and Rehabilitation
    |May 1, 1987
    PubMed
    Summary

    This report details a rare case of obstructive emphysema in a quadriplegic adult caused by mucus plugging. The condition, typically leading to lung collapse, was successfully treated by bronchoscopic aspiration.

    Area of Science:

    • Pulmonology
    • Critical Care Medicine
    • Respiratory Medicine

    Background:

    • Obstructive emphysema is commonly associated with conditions like chronic obstructive pulmonary disease (COPD) or asthma.
    • Mucus plugging in large airways typically results in atelectasis or lobar collapse, not emphysema.

    Observation:

    • A quadriplegic patient presented with obstructive emphysema in a hyperinflated lung, identified via chest radiography.
    • Bronchoscopic aspiration of bronchial secretions from the affected lung resolved the emphysema.
    • The phenomenon recurred in the contralateral lung, indicating a persistent underlying issue.

    Findings:

    • This case represents the first documented instance of obstructive emphysema due to mucus plugging in an adult with otherwise normal airways.
    • The clinical presentation differed significantly from typical outcomes of large airway obstruction by mucus.

    Implications:

    • Highlights a rare differential diagnosis for obstructive emphysema, particularly in neurologically impaired patients.
    • Suggests that mucus plugging can lead to emphysema, challenging established understanding of airway obstruction sequelae.
    • Emphasizes the importance of considering bronchoscopic evaluation for unexplained obstructive emphysema.
