肝动脉彩色多普勒检查对肝硬化诊断价值探讨

目的 探讨肝硬化患者肝动脉的血流动力学特点，为肝硬化的早期诊断提供超声诊断依据。方法 应用彩色多普勒超声检测46例肝硬化患者、50例慢性乙肝患者及42例正常肝脏的肝动脉，测量肝动脉内径及血流多普勒频谱参数，包括收缩期峰值流速（peak systolic velocity，PSV）、平均流速（mean velocity，Vm）、舒张末期流速（end diastolic velocity，EDV）、阻力指数（resistance index，RI）搏动指数（pulsation index,PI）。结果 肝硬化组肝动脉主干内径宽于慢性乙肝组及正常肝组（P〈0．05）；肝硬化组肝动脉PSV、Vm、RI及PI与慢性乙肝组及正常肝组的差异有显著性意义（P〈0．05）。结论 肝动脉的彩色多普勒检查有助于肝硬化的起声诊断．

Clinical Value of detecting hepatic artery by color Doppler ultrasound diagnosis of cirrhosis

Objective] To explore hemodynamic changes of hepatic artery by color Doppler ultrasound in diagnosis of cirrhosis. Method] The hepatic artery were measured by color Doppler ultrasound in 46 cases with cirrhosis, 50 cases with chronic hepatitis B and 42 cases with normal. The inner diameter of hepatic artery and parameter of Doppler blood stream are measured which include peak systolic velocity (PSV), mean velocity (Vm), end diastolic velocity (EDV), resistance index (RI) and pulsation index(PI). Result] The inner diameter of cirrhosis hepatic artery is wider than that of chronic hepatitis B and normal group (P <0.05). PSV, Vm, RI and PI of cirrhosis hepatic artery are different with those of chronic hepatitis B and normal group (P <0.05). Conclusion] The measurement of color Doppler ultrasound is useful for differential diagnosis of cirrhosis.
