摘　　要：目的 :提高对少见起源部位的变异肝动脉的血管造影表现特点的认识。材料和方法 :回顾分析 10 0 0例肝动脉数字减影血管造影资料 ,将Michels肝动脉解剖分型中未提及的所有迷走肝动脉统称之为少见类型的变异肝动脉 ,进一步分析其起源部位、分支、走行及在肝内的分布范围等解剖学特征。结果 :共发现 2 5例存在少见类型的变异肝动脉 ,占2 .5 %。起源于胃十二指肠动脉、腹腔动脉干、胃右动脉分别为 13例 ( 1.3 % ,13 /10 0 0 )、10例 ( 1% ,10 /10 0 0 )和 2例 ( 0 .2 % ,2 /10 0 0 )。结论 :认识少见类型的变异肝动脉 ,在肝癌的经导管动脉内化疗栓塞术中 ,对于有效地寻找肿瘤的血供来源、提高疗效具有重要的意义。Purpose:To improve the understanding of the appearances of the infrequent aberrant hepatic arteries in digital subtraction angiography. Materials and Methods:1000 cases of hepatic arteriograms were retrospectively reviewed. All the aberrant hepatic arteries that did not included in the Michels' hepatic artery classification were called the infrequent hepatic arteries. Their anatomic characteristics such as frequencies, origin, course, branches and distribution within the liver have been described. Results:Of 1000 cases, the infrequent hepatic artery was found in 25 cases (2.5%), which arise from the gastroduodenal artery, the celiac axis and the right gastric artery in 13 cases (1.3%, 13/1000), 10 cases (1%, 10/1000) and 2 cases (0.2%, 2/1000) respectively. Conclusion:It is very important to be familiar with the infrequent hepatic artery in the transcatheter arterial chemoembolization for patients with hepatoma.
