Insights
A child with congenital heart defects and airway issues underwent a novel treatment. A tissue expander, initially used for tracheal compression, later caused a cardiac thrombus requiring emergency surgery.
Area of Science:
- Pediatric Cardiology
- Thoracic Surgery
- Congenital Malformations
Background:
- Congenital conditions like right pulmonary agenesis, tracheal stenosis, and atrial septal defect (ASD) present complex management challenges in children.
- Mediastinal shift in pediatric patients can cause significant tracheal compression, necessitating interventions.
- Intrathoracic tissue expanders are utilized in specific pediatric cases to address airway compromise.
Abstract:
We report the case of a child with right pulmonary agenesis, congenital tracheal stenosis, and atrial septal defect (ASD). At age 2 years, an intrathoracic tissue expander was placed to reduce tracheal compression from mediastinal shift and to enable subsequent atrial septal defect closure. At age 5 years, a right atrial mass was incidentally detected along with right atrial compression caused by the expander. Emergency mass resection was performed, and the mass was diagnosed as a thrombus. The tissue expander was subsequently deflated and removed to prevent further compression. The patient had no recurrence of thrombus or respiratory symptoms during 8-year follow-up.
