Abstract

PURPOSE: Hepatic atrophy has been recognized as a complication of hepatic and biliary disease but we have often found it in follow up CT after transcatheter arterial embolization {TACE). The purpose of this study is to evaluate the characteristics of hepatic atrophy after TACE. MATERIAL AND METHODS: Of 53 patients who had TACE, We evaluated the relationship between the incidence of hepatic atrophy and the number of TACE, and also evaluated the average number of TACE in patients with hepatic atrophy. Of 20 patients who had received more than average number of TACE for development of hepatic atrophy (2 times with portal vein obstruction, 2.7 times without portal vein obstruction in this study), we evaluated the relationship between the tipiodol uptake pattern of tumor and the incidence of hepatic atrophy. RESULTS: There were 8 cases of hepatic atrophy (3 with portal vein obstruction, 5 without portal vein obstruction), average number for development of hepatic atrophy were 2.5 times. As the number of TACE were increased, the incidence of hepatic atrophy were also increased. Of 20 patients who received more than average number of TACE for development of hepatic atrophy, we noted 6 cases of hepatic atrophy in 11 patients with dense homogenous lipiodol uptake pattern of tumor and noted only 1 case of hepatic atrophy in 9 patient with inhomogenous lipiodol uptake pattern. CONCLUSION: Hepatic atrophy was one of the CT findings after TACE even without portal vein obstruction. Average number of TACE was 2.5 times and risk factors for development of hepatic atrophy were portal vein obstruction, increased number of TACE, and dense homogenous lipiodol uptake pattern of tumor.
