摘　　要：目的:研究迷走肝动脉的DSA表现,探讨其对肝癌肝动脉栓塞化疗(TACE)的影响。方法:回顾分析223例肝癌患者的DSA资料,将Michels肝动脉分型Ⅰ型以外的变异肝动脉称之为迷走肝动脉(aberrant hepatic artery,AbHA),统计每组迷走肝动脉的发生率。结果:223例中,AbHA32例,占14.34%,共有40支变异肝动脉,其中迷走肝总动脉(aberrant common hepatic artery,AbCHA)2支(5%,2/40),迷走肝固有动脉(aberrant proper hepatic artery,AbPHA)1只(2.5%,1/40),迷走肝右动脉(aberrant right hepatic artery,AbRHA)24支(60%,24/40),迷走肝左动脉(aberrant left hepatic artery,AbLHA)13支(32.5%,13/40)。有30支变异肝动脉直接参与肿瘤供血,其中24支行TACE治疗,6支行肝动脉化疗(TAI)。结论:正确认识肝动脉的解剖变异特征对提高TACE的成功率、降低手术风险有极其重要的意义。Objective：To research（digital subtraction angiongraphy, DSA） characteristics of aberrant hepatic artery （AbHA） and to study its influence to （transcather arterial chemoembolization, TACE）. Methods： DSA manifestations in 223 cases of hepatic cancer were analyzed retrospectively. The AbHA was defined as hepatic arteries except type I of Michels＇ hepatic artery classification. The frequency of each group was summed up. Results：Of 223 cases, AbHA was found in 32 eases（14.34%）. There were 2 AbCHAs （7.5%）, 1 AbPHA （ 2.5 % ）, 24 AbRHAs （60 % ）, and 13 AbLHAs （ 32.5 % ） of the total 40 AbHAs. 30 AbHAs participated in feeding liver cancer directly, in which treatment by TACE through 23 AbHAs and therapy by TAI through 7 AbHAs were performed. Conclusion： It is very important to understand anatomic characteristics of AbHA for improving success rate of TACE and to prevent its risk.
