[Balloon occluded arterial infusion therapy for malignant hepatic tumors]

A number of reports of regional intraarterial infusion chemotherapy for malignant tumors have been published. Balloon occluded arterial infusion was newly developed by us. Balloon catheter is used for temporal occlusion of the hepatic artery during intraarterial infusion of anticancer drugs. Interruption of the arterial blood flow keeps the drugs at high concentration for a long time in the distal artery to the occluded portion. This procedure has been performed in 87 cases of hepatomas and metastatic liver cancers with the sufficiently good results.
