[Thoracic complications caused by catheterization of the superior vena cava system].

The authors report on 8 observations of respiratory complications, following catheterization of the superior caval system. They mention its clinical features, the seriousness of its development and the diagnostic procedure. The symptomatic treatment is based on the evacuation of the extravasation and the withdrawal of the catheter. Sometimes there has to be recourse to surgery. Finally, the authors emphasize the need for prevention of such typically iatrogenous complications.
