[Venous long-term indwelling catheter and port systems in children. Progress in pediatric oncology].

Long-term indwelling catheters of the Broviac, Hickman, Groshong type, and the Port Systems have proved highly suitable as a supportive measure in pediatric oncology. They are indicated for cytostasis, bone marrow transplantation and long-term parenteral nutrition. They provide reliable and safe venous access for therapy and blood sampling. Therapy is thus faciliated, and the quality of the patient's life is significantly improved by reducing the number of venipunctures required.
