Abstract:
Fifty cases of HCC with 105 procedures of TAI/TAE performed by DSA system were analysed retrospectively.Improperly operative technique used in the procedure of TAI/TAE was found in sixteen cases of this series,included:unsuccessfully superselec- tive catheterization of the hepatic artery in 6 cases,resulting from the unskillful catheteriza- tion or the abnormality of target arteries,etc.Failure recatheterizations of the hepatic arter- ies in the initial or subsequent procedures of TAI/TAE were occurred in the other 6 cases. (because of the stenosis/obstruction of hepatic artery resulted from the intimal injury of the target artery by repeated catheterization,the infusion of anticancer drugs(MMC,5-Fu)and excessive embolization of hepatic artery with gelatine sponge,ete);In the remaining 4 cas- es,the tumor's parasitic vessels-inferior phrenic arterier were neglected due to no abdominal aortography was performed.The results of 16 cases with improperly operative technique of TAI/TAE showed that the decrease of tumor's size was frequently less than 50 per cent,or no change,and in few cases the size of tumor became larger than before.Comparing the de- crease rate of tumor in this 16 cases with the comparative group also confirmed the presence of the significant difference(P
