Plastic Bronchitis-A Promising Intervention for a Challenging Condition

Area of Science:

• Pediatric Cardiology
• Gastroenterology
• Thoracic Surgery

Background:

• Single ventricle pathway and complex cardiac conditions require advanced surgical interventions.
• The Fontan procedure is a palliative surgery for single-ventricle physiology.
• Protein-losing enteropathy (PLE) is a rare but serious complication following Fontan surgery.

Observation:

• A 9-year-old boy with a history of complex cardiac issues and a non-fenestrated Fontan shunt presented with recurrent respiratory symptoms.
• Symptoms included persistent cough with thick, whitish sputum and progressive shortness of breath.
• The patient was diagnosed with protein-losing enteropathy (PLE) after initial medical management failed.

Findings:

• Medical therapy for PLE was ineffective in this pediatric patient.
• Surgical intervention via ligation of the thoracic duct was performed.
• Thoracic duct ligation resulted in a life-saving outcome for the patient.

Implications:

• Thoracic duct ligation may be a viable, life-saving treatment for refractory protein-losing enteropathy post-Fontan.
• This case highlights the importance of considering surgical options for complex pediatric cardiac complications.
• Further research into the mechanisms and optimal management of PLE after Fontan surgery is warranted.
