Stenting of the superior vena cava and right pulmonary artery in a woman with a mediastinal mass and acute respiratory distress syndrome (ARDS).

Abstract We report the case of a woman with a mass in the anterior and middle mediastinum (a non-small-cell lung carcinoma), determining significant compression of both superior vena cava and right pulmonary artery. The patient developed acute respiratory distress syndrome , necessitating intubation and admission to the Intensive Care Unit . Radiotherapy sessions to reduce the mass effect were attempted, without significant clinical improvement. Due to the persistence of severe hypoxemia, stenting of the superior vena cava and the right pulmonary artery was performed, the latter resulting in a significant improvement of the arterial blood gas parameters, allowing extubation of the patient. In our opinion, stenting of the superior vena cava and the pulmonary artery (or its branches) is an effective and safe treatment; it should be considered in similar cases, especially if other - less invasive - treatments fail.
