[Complications of caval catherization (author's transl)].

The following approaches to the caval vein are applicable: Vena saphena, basilica, subclavia, and jugularis. Based on collective studies from the literature and our own experience, the puncture of the internal jugular vein is recommended. The approach via the veins of the lower extremities should no longer be used in adult. Many complications--independent of the approach--are caused by the catheter model applied or by poor application technique or care. A model of our own was developed presenting siliconized polyethylene and a removable needle. As compared to PVC, the rate of inflammation and thrombosis was significantly decreased.
