摘要：

This article was a retrospective review of 10 cases of hepatocellular carcinoma(HCC)resected after transcather hepatie artery embolization. 4 patients were considered to be inop-erable prior to embolotheray. Pathological study revealed no viable tumor cells in 3 cases and exten-sive necrosis(70%～95%)in the remaining 7. Various degrees of necrosis were found in the satellite lesions tumor thrombus in the portal vein and the infiltrating tumor cells in the capsule,5 cases showed marked thickening of the capsule. The mean and median survival times were 24. 8 and 24.5 months respectively. The authors were of the opinion that hepatic artery embolization was an effec-tive method which might convert an unresectable HCC into a resectable one.The interval between embolization and operation was preferably more than 3 months. A modified histopathologic classifica-tion after embolization was suggested and evaluation of embolotherapy as a pre-operative procedure was investigated.
