Insights
Surgical thoracic enlargement in Jeune syndrome initially improved breathing but failed long-term due to rib resorption. This case highlights the limited efficacy of this intervention for severe thoracic insufficiency syndrome.
Area of Science:
- Pediatric Surgery
- Genetics
- Respiratory Medicine
Background:
- Jeune syndrome, also known as asphyxiating thoracic dysplasia, is a rare skeletal ciliopathy characterized by severe thoracic hypoplasia.
- Thoracic insufficiency syndrome in Jeune syndrome leads to respiratory compromise and high mortality.
- Surgical intervention, such as thoracic enlargement, is sometimes considered to improve respiratory function.
Observation:
- A case of Jeune syndrome is presented where a child underwent surgical thoracic enlargement at 4 months of age.
- Initial postoperative improvement in respiratory status was observed.
- However, progressive resorption of interposed ribs led to thoracic re-narrowing and clinical deterioration.
Findings:
- A second surgical attempt at 8 months of age did not yield improvement.
- The child had developed significant comorbidities, including pulmonary hypertension and broncho-pulmonary dysplasia, by the time of reoperation.
- These later complications likely precluded a positive outcome from further surgical intervention.
Implications:
- This case suggests that while initial thoracic enlargement may offer temporary respiratory support, long-term benefits in Jeune syndrome are limited by factors like rib resorption.
- The development of pulmonary hypertension and broncho-pulmonary dysplasia significantly impacts prognosis and may contraindicate further surgical interventions.
- Careful patient selection and consideration of the syndrome's natural history are crucial when evaluating surgical options for Jeune syndrome.
Abstract:
We report about a child with Jeune-syndrome in whom surgical enlargement of the thorax at the age of 4 months was performed. In the beginning there was a significant improvement of the respiratory situation. Due to resorption of the interposed ribs there was again a shrinking of the thorax and a deterioration in the child's condition. A reoperation at the age of 8 months couldn't improve the situation anymore, because at that time the child had already additional problems such as pulmonary hypertension and broncho-pulmonary dysplasia. We overview the literature and line out our opinion about the indication for surgical enlargement of the thorax in children with Jeune syndrome.
