[Value of digital subtraction angiography in the imaging of a subcutaneously implanted, intra-arterial chemotherapy catheter].

: Intraarterial chemotherapy is already a commonly accepted treatment method in isolated liver metastases. The high risk of transcutaneous injection of chemotherapeutic substances in the implanted catheter system requires a passage examination before the beginning of therapy. 32 digital subtraction angiograms for examination and documentation of the implanted catheter have been performed in 15 patients. The DSA seems to be a good visualisation technique for the implanted chemotherapy catheter systems.
