Postpneumonectomy syndrome in children: advantages and long-term follow-up of expandable prosthesis

Area of Science:

• Pediatric Thoracic Surgery
• Respiratory Medicine
• Biomedical Engineering

Background:

• Pneumonectomy in children can cause severe mediastinal shift, leading to bronchial stretching and respiratory failure.
• Post-pneumonectomy syndrome presents a significant challenge in pediatric surgical care.

Purpose of the Study:

• To evaluate the efficacy of intrathoracic prosthesis insertion for correcting post-pneumonectomy syndrome in children.
• To assess the impact of expandable prostheses on mediastinal position and respiratory function.

Main Methods:

• Retrospective analysis of 42 children undergoing pneumonectomy, with 7 treated for post-pneumonectomy syndrome.
• Surgical insertion of expandable prostheses, with periodic saline injections to maintain mediastinal position.
• Follow-up included pulmonary function tests and assessment of prosthesis management, including replacement with breast prostheses in adolescence.

Main Results:

• A mean of 5 years post-pneumonectomy before prosthesis implantation.
• Significant improvement in obstructive syndrome observed in most patients post-intervention.
• Mean follow-up of 6 years with all patients demonstrating positive outcomes.

Conclusions:

• Intrathoracic prosthesis insertion dramatically improves clinical symptoms and reduces obstructive syndrome.
• Expandable prostheses facilitate progressive, well-tolerated mediastinal repositioning and accommodate growth.
• This approach offers a viable solution for managing post-pneumonectomy syndrome in pediatric patients.
