BACKGROUND/PURPOSE: Pneumonectomy in children can be complicated by a severe mediastinal shift, which leads to bronchial stretching resulting in severe respiratory failure. This postpneumonectomy syndrome can be corrected by inserting a prosthesis in the empty side of the chest.
METHODS: Forty-two children, from 6 months to 15 years old, underwent a pneumonectomy. Seven of these patients were treated surgically for severe manifestations of postpneumonectomy syndrome. First insertion of an expandable prosthesis was followed up in 5 cases by its replacement with a breast prosthesis in adolescence. The expandable prosthesis was injected periodically with saline solution to maintain the mediastinum in a midline position as the children grew.
RESULTS: The mean delay between pneumonectomy and first prosthesis implantation was 5 years (range, 11 months to 8 years). Pulmonary function tests showed a substantial improvement in the obstructive syndrome in all patients except one, in whom the functional improvement was moderate. The mean follow-up after the expandable prosthesis implantation was 6 years (range, 6 months to 10 years) and all patients are doing well.
CONCLUSIONS: The insertion of an intrathoracic prosthesis can dramatically improve the clinical symptoms and reduce the functional obstructive syndrome. The expandable prosthesis allowed for progressive, well-tolerated recentering of the mediastinum and adjustment for growth.
