Study hypothesis
The primary objective is to show whether a modified Seldinger technique is superior to the conventional surgical approach in implanting a port-catheter-system with less failures than the prior strategy. The modified Seldinger technique consists of a set including an introducer, a guide wire and a pull-away-sheath to place the catheter correctly.

Treatment
Patient information sheet
Condition
Port-catheter-system implanting
Intervention
Patients with benign or malignant diseases who demand a safe and permanent venous access e.g. for chemotherapy and/or parenteral nutrition, will be randomised to:
Group 1: A modified Seldinger-technique with a guide wire, dilatator and a pull-away-sheath is used after preparation of the cephalic vein to place the catheter
Group 2: Conventional venae section technique is used. The catheter will be inserted directly without a pull-away-sheath or a guide wire.
Please note that this trial was successfully completed in May 2007.
