肝硬化合并肝癌患者血流动力学超声影像特点

Further discussion on hemodymamics of liver cirrhosis combined with hepatic carcinoma

【目的】探讨肝硬化合并肝癌患者肝固有动脉及腹腔动脉的血流动力学变化。【方法】对3组(对照组30例、肝硬化组47例及肝硬化合并肝癌组45例)共122例研究对象进行灰阶、彩色多普勒及脉冲多普勒超声检查,测量肝固有动脉及腹腔动脉的内径、最高血流速、最低血流速、平均血流速及阻力指数;计算肝固有动脉及腹腔动脉的血流量及二者的血流量之比。【结果】肝硬化患者肝动脉、腹腔动脉的血流量较正常人明显增加,肝硬化合并肝癌患者肝动脉、腹腔动脉的血流量较肝硬化患者高。肝硬化合并肝癌组的肝固有动脉与腹腔动脉血流量之比与正常组及肝硬化组比较具有统计学差异。【结论】肝固有动脉及腹腔动脉的血流动力学改变,特别是二者的血流量之比的改变可为诊断肝癌、肝硬化提供参考信息。

【Objective】 Rediscussion the proper hepatic artery（PHA） and the celiac artery（CA） hemodymamics of the patients with liver cirrhosis combined with hepatic carcinoma.【Method】 A total of 30 normal cases,45 cases with hepatic cirrhosis and liver cancer and 47 cases with hepatic cirrhosis were detected with gray scale,color Doppler and pulsed Doppler to measure the diameter,maximal,mimimal and mean velocities,resistance index（RI） and blood volume of CA and PHA.And calculated the blood volume ratio of PHA and CA.【Result】 The blood bolume of CA and PHA in cirrhosis group was higher than that of normal group,blood volume of CA and PHA in hepatic cirrhosis and liver cancer group was higher than that of hepatic cirrhosis group.There was statistical difference of the blood volume ratio of PHA and CA between hepatic cirrhosis and liver cancer group and the normal group and hepatic cirrhosis group.【Conclusion】The blood volume changes of CA and PHA,especially the ratio of HA blood volume and CA blood volume,is helpful to offer diagnostic information for patients with hepatic cirrhosis and/or liver cancer.
