[Personal catheter technic for intra-arterial chemotherapy in cancers of the head and neck].

Regional intraarterial chemotherapy can display its advantages as augmented concentrations of effective substances within the tumour tissue and lower systemic side effects, only if tumour perfusion can be carried out superselectively. For different reasons, the present techniques have not been accepted for extensive clinical use. A new catheter technique is, therefore, presented that is appropriate for both clinical routine and superselective tumour perfusion.
