目的:探讨彩色多普勒超声检查(CDFI)测定慢性乙型肝炎(CHB)和肝硬化(LC)血流动力学改变的意义。方法:应用CDFI对CHB74例和LC90例常规检测肝、脾大小及其边缘结构、内部回声,同时显示门静脉主干、门静脉左支矢状部、门静脉右支及脾门处脾静脉,取得满意图像后描记多普勒频谱、测量峰值速度,取3个频谱平均值为所需值,并与对照组60例进行比较。结果:与对照组相比,除轻度CHB外,中、重度CHB及LC皆有显著降低(P<0.01)。结论:CDFI对CHB及LC的病情监测有一定实用价值。
Objective: To investigate the significance of color Doppler ultrasonography (CDFI) in determining hemodynamic changes in chronic hepatitis B (CHB) and cirrhosis (LC). Methods: CDFI was used to detect the liver and spleen size, the size of the spleen, the edge structure and the internal echo of the liver and spleen, and the main portal vein, the left branch of the portal vein, the right branch of the portal vein and the splenic vein at the splenic portal. The Doppler spectrum was traced and the peak velocity was measured. The average value of the three spectra was taken as the desired value, and compared with 60 cases in the control group. Results: Compared with the control group, moderate and severe CHB and LC were significantly decreased except for mild CHB (P <0.01). Conclusion: CDFI has certain practical value in the monitoring of CHB and LC.
