摘要
目的:研究肠系膜上动脉供血型(即变异肝动脉起源于肠系膜上动脉)肝癌的血管造影表现及插管技术。材料与方法:回顾分析30例肠系膜上动脉供血型肝癌的DSA及介入资料,统计血管解剖变异的发生率,对其起源、走行、分支、分布等解剖学特征及其与血管插管的关系进行描述和分析。结果:212例肝癌中肠系膜上动脉供血型30例,其中副肝右动脉10例,替代肝右动脉15例,肝总动脉3例,腹腔动脉干起源于肠系膜上动脉2例。23例肠系膜上动脉发出替代或副肝右动脉者,20例腹腔动脉造影表现为肝右动脉细小或缺如,肝右叶出现无血管区。RH导管超选择性插管成功19例,未成功者改用Cobra导管以及结合微导管技术后获得成功。结论:肠系膜上动脉供血型肝癌是一种比较常见的肝动脉变异性供血,熟悉其血管变异的特点对肝动脉化疗栓塞术具有重要的意义。
Purpose:To investigate angiographic characteristics and interventional catheterization techniques of hepatocullular carcinoma(HCC) fed by aberrant hepatic arteries arising from superior mesenteric artery(SMA),namely SMA type.Materials and Methods:DSA manifestations and data of interventional treatment in 30 SMA type HCCs were retrospectively reviewed.The frequency of aberrant arteries was summed up statistically and their anatomic characteristics(such as,origin,course.branches and distribution) and relationship with catherization were described and analysed.Results:Of 212 HCC cases,SMA type HCCs were found in 30 cases,including accessory right hepatic atery 10 cases,replaced right hepatic artery13 cases,common hepatic artery 3 cases and celiac artery arising from SMA 2 cases.Of 23 cases with accessory or replaced right hepatic arteries,on celiac angiography,right hepatic arteries were small orabsent in 20 cases,and there was an avascular zone on the right liver.Superselective catheterization was successful in 19 cases by using RH catheter,the rest acquired successful superselective catheterization by using Cobra,Simmon catheter and microcatheter.Conclusion:SMA type is a common variation,A knowledge of this variation is very important in transcatheter arterial chemoembolization for HCC.
