N2 - Continuous chemotherapy was administered to 82 patients through the hepatic artery via Infusaid pumps. In order to obtain a primary status and to evaluate the success of therapy, the perfusion patterns of the liver and of the existing tumor masses in the liver were estimated by conducting arterial angiocomputed tomographies (AACTs) immediately after pump implantation of every 3 months thereafter. In 70% of the patients, findings showed both liver lobes to be homogeneously perfused, 24% demonstrated distinct inhomogeneities. The response of the latter cases should depend primarily on the efficacy of the administered cytostatic agent. Six percent of the patients showed selective perfusion of either the left or right hepatic lobe. In these cases, only me perfused liver regions exhibited stable disease or regression of the metastases, whereas the metastases of the nonperfused regions progressed. At 3-month follow-up, the majority of the patients (50-57% showed homogeneous hepatic perfusion. Inhomogeneities were found in 26-36% of the patients, 12 patients demonstrated incomplete perfusion. There was no association between the perfusion patterns of the metastases or of the prechemotherapeutic liver involvement and the response of the metastases to regional chemotherapy. In regional chemotherapy, liver perfusion should be controlled both intraoperatively or directly postoperatively and during therapy.
