[Chemoembolization of the hepatic artery combined with intraportal cytostatic infusion--a new concept in the regional chemotherapy of liver metastases].

: At present international the regional cytostatic chemotherapy for hepatic metastases is used by the intraarterial way. Newest methods are the technically very pretentious intraarterial perfusion with venous hemofiltration and the chemo-embolization of the hepatic artery requiring meanwhile an adjuvant systemic chemotherapy because the chemo-embolization influences only the arterially supplied part of the metastases. By the combination of the transumbilical intraportal chemotherapy formerly developed in the Central Institute for Cancer Research Berlin-Buch with the intraarterial chemo-embolization it is possible to reduce considerably the technical expenditure and to increase the regional concentration of cytostatics simultaneous avoiding the load of the whole organism. The bases of this new method and the technical procedure are discussed.
