[Transcatheter hepatic segmental chemo-Lipiodol-embolization against hepatocellular carcinoma accompanied by tumor thrombosis in the portal vein].

: We performed transcatheter hepatic segmental chemo-Lipiodol-embolization against hepatocellular carcinoma accompanied by tumor thrombosis in the portal vein. CT scan after embolization demonstrated good Lipiodol accumulation in the tumor thrombosis in some cases. In one resected case, remarkable necrosis of tumor thrombosis was proved histologically. In five non-resected cases, 6-month survival rate was 100%. We hope this therapeutic method can be useful for hepatocellular carcinoma with tumor thrombosis in the portal vein.
