摘　　要：AIM To evaluate the therapeutic effects of segmental transcatheter arterial embolization for primary hepatocellular carcinoma, and to recognize the menifestation and clinical value of lipiodol overflow into portal veins surrounding the tumors. METHODS A total of 50 cases of nonresectable primary hepatocellular carcinoma underwent segmental transcatheter arterial embolization. Two methods of superselective segmental catheterization were used, one was the method of wire guiding, and the other the technic of co axial infusion catheter. RESULTS The 1 , 2 , 3 and 4 year cumulative survival rates of 50 cases with segmental transcatheter arterial embolization for primary hepatocellular carcinoma were 83 8%, 65 4%, 42 9% and 24 5% respectively. The incidence of the lipiodol overflow into portal veins was 64%. The overflow of lipiodol into portal veins, represented as 3-5 grade branches of portal veins visualized by lipiodol, was “star like” or “tree like”, and there was a relatively large vessel in the center surrounded with radicalized small branches of vessels. CONCLUSION The lipiodol overflow into portal veins was one of the signs of complete embolization for tumors, and may play a partial role in embolizating the portal venous supply for hepatocellular carcinoma.
