摘要
目的:探讨三维超声监测肝细胞性肝癌介入术后改变的价值。材料和方法:23例肝细胞性肝癌病人,行经导管肝动脉化疗栓塞术(transcatheter arterial chemoemblization,TACE)加瘤内注入无水乙醇(percutaneous ethanol injection,PEI)治疗,分别于治疗前(T0)、治疗后1个月(T1)、2个月(T2)、3个月(T3)行二维及三维超声检查。结果:治疗后二维超声图像肿瘤边界欠清晰,内部回声不均匀;治疗后从T1时间点起内部血流即有明显减少,肿瘤的最大径线值与治疗前比于T3有明显变化(P<0.05)。三维重建图像计算的肿瘤体积于T2显示有变化。血管指数VI从治疗后1个月即有变化(P<0.05),并持续至治疗后3个月。结论:三维超声可以定量研究肝细胞性肝癌介入治疗术后改变,在测量肿瘤大小方面比二维图像敏感。与二维超声图像相结合,可以为临床评价治疗效果提供有意义的信息。
Purpose： The purpose of the study was to investigate the value of three - dimensional ultrasound in monitoring the change of livers after interventional therapy in hepatocellular carcinoma patients.Materials and Methods： Transcatheter arterial chemoemblization（TACE） and percutaneous ethanol injection（PEI） were performed at twenty - three HCC tumors in patients. Two - and Three - dimensional ultrasound was examined before to and after the interventional theraphy 1 mo（T1）, 2mo （T2）, and 3 mo（T3） respectively. Results： There is significant difference of the large diameter of tumors at T3 compared with that of TO. The volume of tumors calculated by 31） imaging is different from that of TO at T2. CDFI shows that the blood flow decreases obviously from T1 to T3.Conclusion： More changes of liver tumors after interventional therapy can be quantitively investigated by 3D ultrasound. 31） imaging is more sensitive than 2D imaging in measuring the size of tumors. 31） imaging can offer useful imformation for clinical evaluation the interventional therapy effect combined with 2D ultrasound.
