Insights
This case report details a rare instance of a bridge-like subglottic stenosis in an infant following endotracheal intubation. The lesion, a fibrinoid pseudomembrane, caused stridor but resolved to a mild stenosis.
Area of Science:
- Pediatric Otolaryngology
- Respiratory Medicine
- Medical Case Reports
Background:
- Subglottic stenosis is a known complication of endotracheal intubation in infants.
- Early identification and management are crucial for preventing airway compromise.
Observation:
- An infant developed stridor after endotracheal intubation for RSV infection.
- Endoscopy revealed a unique bridge-like subglottic mucosal lesion, identified as a fibrinoid pseudomembrane.
Findings:
- Histopathology confirmed a fibrinoid pseudomembrane causing a bridge-like subglottic stenosis.
- The lesion led to significant airway narrowing, initially presenting as stridor.
- Post-treatment, the stenosis resolved to Grade 1 without respiratory compromise.
Implications:
- This is the first reported case of a post-intubation bridge-like fibrinoid pseudomembranous subglottic lesion in an infant.
- Highlights the importance of thorough endoscopic evaluation for unusual airway lesions.
- Contributes to understanding rare iatrogenic airway complications in neonates and infants.
Abstract:
We present an infant with post-intubation stridor caused by a bridge-like subglottic stenosis. At the age of 6 weeks he suffered from a RSV infection with the need for endotracheal intubation. At week 10 acute respiratory distress required a re-intubation. Flexible endoscopy was suggestive for laryngomalacia. Rigid endoscopy revealed a subglottic laterolateral mucosal bridge resulting in a doubling of the airway lumen. Histopathological examination showed a fibrinoid pseudomembrane. Follow up endoscopy showed a grade 1 posterior subglottic stenosis without respiratory compromise. This is the first case in the literature of an infant with a post-intubation bridge-like fibrinoid pseudomembranous subglottic lesion.
