摘要
目的研究原发性肝癌合并门静脉癌栓时门静脉和肝动脉的超声表现和血流动力学变化。方法应用超声分别研究肝癌合并门静脉癌栓组和对照组门静脉、肝动脉的二维和多普勒超声改变及血流动力学各项指标。结果合并癌栓组较对照组门静脉内径明显增宽,流速降低(P<0.05);肝动脉显示率和流速明显提高(P<0.05)。结论应用彩超检查获得肝癌合并门静脉癌栓肝内血流的重要指标,对诊断、指导治疗和判断预后有重要意义。
Objective To study the changes of liver blood flow with or without portal vein thrombus （PVTT） in hepatocellular carcinoma. Methods The hepatocellular carcinoma patients with PVTT （n = 26） and without PVTT （n = 35 ） were enrolled. The diameter and the velocity of hepatic arterial （HA） and portal vein （PV） were measured with color Doppler flow imaging in all patients. Results In the patients with PVTT, the diameter of PV dilated and the velocity of PV dropped significantly and the velocity of HA rised obviously, as compared with those without PVTT. Conclusion The index of HA and PA is very important to guide the therapy of hepatocellular carcinoma.
