RESUMO
Objective: To investigate the effect of microcatheter in chemoembolization of HCC. Methods Using 4 - F - 5 - F Yashiro/Kouno and 5 - F Hook catheters as guiding catheter,3 - F microcatheter was put into segmental hepatic artery or tumor feeding artery and chemoembolization was carried out. Results All 35 cases had 50 times chemoembolizations totally, of them, 16 cases with small HCC had segmental TAE and 19 cases with large but localized HCC had right/left hepatic artery or anterio/posterio brtanch of right hepatic artery embolization, 1-2 year survial rates were 100%, 87. 5% and 52. 6%,42. l% respectively after TAE. Liver function damage after TAE was slight and no complications occurred. Conclusion Improving embolization precision by using microcatheter is valuable in the cases with small HCC or large but localized HCC with tortuous hepatic artery,hepatic artery stenosis after injury and variations.
