摘　　要：目的探讨胃右动脉起源变异在肝细胞癌介入治疗中的指导意义。方法对72例原发性肝细胞癌患者行64层螺旋CT肝脏动态增强扫描,动脉期采用容积再现(VR)及最大密度投影(MIP)重建技术,追踪重建显示胃右动脉的起源与肝动脉的关系,并与血管造影结果对比。结果在72例原发性肝细胞癌患者中,VR及MIP清楚显示胃右动脉起源者43例,显示率为59.8%。胃右动脉起源于肝固有动脉19例,肝左动脉17例,胃十二指肠动脉4例,肝右动脉2例,肝总动脉1例。三维重建结果显示与血管造影一致。结论胃右动脉起源变异多发自肝左动脉,64层螺旋CT三维重建可提供胃右动脉血管影像资料,对介入治疗具有实用意义。Objective To discuss the clinical significance of anomalous origination of right gastric artery in interventional treatment for hepatocellular carcinoma （HCC）. Methods The dynamic enhanced CT scanning of the liver with a 64-slice spiral CT unit was performed in 72 HCC patienls. In arterial phase, maximum intensity projection （MIP） and volume reconstruction technique （VRT） were used to ohserve the origin of the right gastric artery and its relationship with the hepatic artery. The findings were compared with the angiographie results. Results Of the total 72 cases, the anomalous origin of the right gastric artery was found in 43 （59.8%）. The anomalous origins of the right gastric artery included proper hepatic artery （n = 19）, left hepatic artery （n = 17）, gastroduodenal artery （n = 4）, right hepatic artery （n = 2） and common hepatic artery （n = 1）. The results obtained from three-dimensional reconstruction were in good accordance with angiographie findings. Conclusion The anomalously originated right gastric artery most commonly originates from the left hepatic artery. Three-dimensional reconstruction obtained from the 64-slice spiral CT scans can provide the clear and reliable images of the right gastric artery, which is very helpful for the interventional procedure.
