Plastic Bronchitis: Extensive Cast Expectoration in a 6-Year-Old Boy with Fontan Circulation

Area of Science:

• Pediatric Cardiology
• Pulmonology
• Medical Case Reports

Background:

• Hypoplastic left heart syndrome (HLHS) and Fontan circulation present unique challenges in pediatric care.
• Plastic bronchitis is a rare but serious complication, particularly in patients with Fontan-associated physiology.
• Recurrent or severe cases of plastic bronchitis necessitate careful clinical evaluation and management.

Purpose of the Study:

• To report a rare case of extensive plastic bronchitis in a pediatric patient with Fontan circulation.
• To illustrate the clinical presentation and diagnostic challenges associated with severe bronchial casts.
• To emphasize the complexities in managing plastic bronchitis within the context of complex congenital heart disease.

Main Methods:

• Case presentation of a 6-year-old boy with HLHS and Fontan circulation.
• Clinical observation of recurrent, severe productive cough and bronchial cast expulsion.
• Review of diagnostic findings and therapeutic response.

Main Results:

• The patient presented with a large, extensive bronchial cast, indicative of severe plastic bronchitis.
• Despite initial therapeutic response, the condition recurred with significant symptom exacerbation.
• The size of the cast was notable, underscoring the severity of the condition in this pediatric patient.

Conclusions:

• Plastic bronchitis is a challenging complication in patients with Fontan circulation.
• Effective treatment strategies for extensive bronchial casts in pediatric Fontan patients remain difficult.
• This case underscores the need for vigilant monitoring and tailored management approaches for plastic bronchitis in this population.
