Segmental transcatheter arterial embolization for primary hepatocellular carcinoma

The 1-, 2-, 3-, 4- year cumulative survival rates of 50 cases of segmentaltranscatheter arterial embolization for primary hepatocellular carcinoma were 83.8%, 65.4%, 42.9%, 24.5%. The manifestation and clinical value of lipiodol overflow intoportal veins surrounding the tumor were discussed in our study. The occurrence rate ofthe lipiodol over-flow into portal veins in segmental TAE was 64%, We suggestedthat the lipiodol overflow into portal veins was one of marks of complete embolizationfor tumors, and may played a part role in embolizating the portal venous supply of thehepatocellular carcinoma.
