Objective To evaluate and compare the dirferent result in hypertrophy of remained live Iobe after double and slngle embolization. Methods Combined hepatic arterial embolization(HAE) with portal venous embollzation(PVE), HAE and sham operation were carrled on the medlan and left lobes of the livers in normal and cirrhotic rats respectively. Three days later, the volume of the right lobe of the liver and its mitotic index and GPT content pergram protein were measured. ResuIts In normel rats, the indicatlons mentioned increased significantly ln experimental rats compared to control rats. The indications mentloned above also increased significantly in HAE+PVE group compared to HAE group. However, they increased more slightly in cirrhotic rats than in normal rats. Enlargement of the nonembolized part of the liver after double embolization is a result of hypertrophy, which enhanced the reserve functoon of the liver. Conslderlng various degree of hypertrophy of liver cell and enhancement of reserve function, double emboIization is more excelIent than singIe embolization when the same voIume Iiver is embolized.
