[Cavathrombosis: a complication of cava long-time catheter].

The Vena-Cava-Catheter is necessary in long term parenteral nutrition. The thrombosis of Vena Cava as a complication of the long term Cava-catheter is seldom. It is impossible to show the incidence of Vena Cava thrombosis, because there must not be clinical signs. In six cases we could show the thrombosis of Vena Cava. Sepsis, changing of the catheter, distance, large catheters and hyperosmolaric solutions are responsible for thrombosis of Vena Cava.
