目的 :应用彩色多普勒超声 (CDFI)检测肝硬化早期诊断的临床特征 ,测定门静脉系统血流参数 ,提高早期诊断率。方法 :采用 (VIVID3 )型彩色多普勒超声仪 ,对于正常人及早期肝硬化患者门静脉、脾静脉系统血流动力学进行对照。结果 :早期肝硬化门静脉内径明显增宽、血流速度减慢。二者之间有显著性差异 (P <0 0 5 )。结论 :早期肝硬化门静脉处于高循环动态状态 ,用CDFI观察门静脉及脾静脉系统血流动力学变化 ,有助于早期肝硬化的诊断
Objective: To evaluate the clinical features of early diagnosis of cirrhosis by color Doppler ultrasound (CDFI), determine the parameters of portal vein blood flow and improve the early diagnosis rate. Methods: VIVID3 color Doppler was used to compare the hemodynamics of portal vein and splenic vein in normal subjects and patients with early-stage cirrhosis. Results: The diameter of portal vein in early cirrhosis was obviously widened, and the blood flow velocity was slowed down. There was a significant difference between the two (P <0 05). Conclusions: The portal cirrhosis in high cirrhosis is in a hyper-circulatory state. CDFI can be used to observe the hemodynamic changes of the portal and splenic venous system, which is helpful for the diagnosis of early cirrhosis
