[The right postpneumonectomy syndrome].

Two patients with a so-called right-sided postpneumonectomy syndrome are described. The syndrome results from a marked mediastinal shift towards the vacant hemithorax, primarily after a pneumonectomy performed in early childhood. The trachea is compressed by the aortic arch and distorted by the mediastinal shift. The left main bronchus is compressed between the left central pulmonary artery and the descending aorta. This can result in tracheobronchomalacia and recurrent pneumonia in the remaining lung.
