ABSTRACT
The negative pressure achieved in the hemi thorax in the case of lung pneumonectomy has consequences on the mediastinum organ statics. This condition results through the other lung expansion. These changes are common, but rare in adult lung pneumonectomy. In the case of right lung pneumonectomy, the mediastinum moves to the operated part and disturbs the function of the vessels and cavities with thin wall or low pressure (vena cava, right atrium). These aspects are not observed in the case of left lung pneumonectomy. Taking this into consideration the authors present the case of a young woman with right lung pneumonectomy, an intervention made in childhood, at ten years old. After sixteen years of evolution a serious mediastinum re-shuffle was discovered, the heart was moved in the right hemi thorax, with a dextrocardia like aspect. This case is interesting because it raises positive and differential diagnosis problems--dextrocardia, associated disorders, serious complications.
