Fifty-two patients with unresectable hapatocelluar carcinoma were divided into 2 groups. Group A (n=24) received lipiodolization with gelatin sponge and group B (n=28) lipiodolization alone. Angiography after hepatic arterial chemoembolization revealed a satisfactory accumulation of lipiodol and obliteration of the micovasculature in the tumors in both groups. However, prolonged obliteration of proximal hepatic arteries was noted in 70%-80% of patients in group A, in contrast to the patency of the arteries in group B. Collateral circulation was found more frequently in group A than in group B, in which recanalization of tumor vessels and phenomenon of iodized oil "wash-out" were seen. There were no significant differences in therapeutic effects in patients with low risk. In those with high risk, the response rates were 28.6% and 64.2%. The half-year survival rates were 28.5% and 62.8%, 1-year survival rates 7.1% and 27.5%, and 2-year survival rates 0% and 13.7% in group A and B respectively. The differen
