Pulmonary edema secondary to chronic upper airway obstruction. Hemodynamic study in a child
Insights
Adenoid hypertrophy can cause severe respiratory and heart issues in children, including pulmonary hypertension and edema. Surgical removal of adenoids (adenoidectomy) rapidly resolved these symptoms, demonstrating its effectiveness.
Area of Science:
- Pediatric Pulmonology
- Cardiology
- Otolaryngology
Background:
- Adenoid hypertrophy is a common condition in children that can lead to upper airway obstruction.
- Severe cases can manifest with significant cardiopulmonary complications, including pulmonary hypertension, cor pulmonale, and pulmonary edema.
Observation:
- A case study of a 22-month-old girl presenting with hypoventilation, pulmonary hypertension, cor pulmonale, and pulmonary edema secondary to adenoid hypertrophy.
- The patient exhibited symptoms consistent with significant cardiopulmonary distress.
Findings:
- Adenoidectomy led to rapid and complete resolution of all respiratory and cardiovascular symptoms within 24 hours.
- Hemodynamic monitoring confirmed a return of pulmonary artery pressure to normal levels 48 hours post-surgery.
- Pulmonary edema was determined to be secondary to biventricular heart failure, exacerbated by negative intrathoracic pressure from airway obstruction.
Implications:
- This case highlights the critical link between upper airway obstruction from adenoid hypertrophy and severe cardiopulmonary compromise in pediatric patients.
- Early diagnosis and surgical intervention (adenoidectomy) can effectively reverse these life-threatening conditions.
- Understanding the pathophysiology, including the role of negative intrathoracic pressure, is crucial for managing this syndrome.
Abstract:
A 22-month-old girl with the syndrome of hypoventilation, pulmonary hypertension, cor pulmonale and pulmonary edema due to adenoidal hypertrophy is described. Adenoidectomy resulted in relief of all symptoms and signs within 24 h. Hemodynamic study using pulmonary artery catheter showed that the pulmonary artery pressure returned to normal 48 h after relief of the obstruction. The normal left ventricular end-diastolic pressure, measured throughout the period of obstruction, in the presence of severe pulmonary edema, could suggest a non-cardiogenic "low pressure" pulmonary edema. However, the highly negative pleural pressure which existed during upper airway obstruction indicated an elevation of transmural left ventricular end diastolic pressure (compared to pulmonary wedge pressure) and thus, suggested that the pulmonary edema in this syndrome is secondary to both - right and left heart failure.
