Prevention and management of liver injury via hepatic arterial chemoemboliza- tion;and improvement of its curative effects,223 among 704 patients with more than three years survival after the treatment were assessed on liver tissue and vascularity and lives function.Hepatic clrrhosis(189/223,85.56%)were found rapidly and seriously on CT scan follow-up,Vascular occlusion(3.4%),localised stenosis(fringed duct wall,asymmetric and circumcrsent)were caused latrogenically and generalised stenosis(linear or serrated)could be found unavoidably via chemotherapeutic drugs,lipoidal and gelatine sponge.Collateral bran- ches were found originating from superior mesenteric artery etc.Liver dysfunction and portal hypertension(98/119,82.35%)were the common fatal causes.Acorrding to this assessment, authors expressed the opinoin on the resime of long-term effects by hepatic arterial chemoem- bolization.
