Clinical significance of anatomical variation of hepatic artery in interventional therapy for HCC

Objective To study DSA characteristics of anatomic variantion of hepatic artery and its clinical significance in TACE.Methods DSA manifestations in 223 cases of hepatic cancer were analyzed retrospectively.Origin and course and distribution of anatomic variantion of hepatic artery as well as influence on TACE were further analyzed.The frequency of each group variant hepatic artery was summed up.Results Of 223 cases,variant hepatic arteries were found in 32 cases(14.34%),There were 2 variant common hepatic arteries(7.5%) and 1 variant proper hepatic artery(2.5%) and 24 variant right hepatic arteries(60%) and 13 variant left hepatic arteries(32.5%) of the total 40 variant hepatic arteries.30 AbHAs participated feeding liver cancer directly,treatment by TACE through 23 variant hepatic arteries and therapy by TAI through 7 variant hepatic arteries.Conclusion It is very important understanding anatomic characteristics of variant hepatic arteries for improving success rate of TACE and preventing its risk.
