Insights
Foreign body aspiration in children is common. A 14-year-old girl successfully coughed out a scarf pin after initial bronchoscopy attempts, avoiding further procedures.
Area of Science:
- Pediatric Pulmonology
- Emergency Medicine
Background:
- Foreign body aspiration is a significant cause of accidental injury and death in young children.
- Bronchoscopic retrieval is the standard treatment for inhaled foreign bodies.
Observation:
- A 14-year-old female presented with a foreign body (scarf pin) in her airway.
- Initial flexible bronchoscopy partially advanced the pin but it was reaspirated into the lower trachea.
Findings:
- Despite initial challenges and planned rigid bronchoscopy, the patient spontaneously expectorated the foreign body.
- This case highlights an unusual resolution of a potentially dangerous airway obstruction.
Implications:
- While bronchoscopy is effective, spontaneous resolution can occur, potentially avoiding invasive procedures.
- This case underscores the importance of patient monitoring and the possibility of unexpected outcomes in airway foreign body management.
Abstract:
Accidental foreign body aspiration is more common in children than in adults. It is one of the most common causes of accidental death in young children. Retrieval of the foreign body by rigid or flexible bronchoscopy is successful in the majority of cases. We describe a case of a 14-year-old girl who inhaled a scarf pin. Flexible bronchoscopy was partly successful and managed to bring the pin up from a segmental bronchus into the left lower lobe bronchus and then into the throat. Unfortunately, it was reaspirated by the patient into the lower trachea. A rigid bronchoscopy under general anesthesia was planned; however, the patient managed to cough the foreign body out spontaneously, thus avoiding further interventions.
