彩色多普勒超声对肝硬化门脉血流动力学测定结果分析

Measurement of cirrhosis portal hemodynamics with color Doppler ultrasonography

目的 :探讨彩色多普勒超声对肝硬化门脉系统的血流动力学的改变对临床诊断的指导意义。方法 :运用彩色多普勒超声检查 2 2例肝硬化患者门脉系统的血流参数并与 2 0例健康对照组进行对比分析。结果 :肝硬化患者门脉主干内径与对照组相比明显增宽 ,血流速度降低 ,血流量增加 ,门脉左、右支血流量之和小于门脉主干血流量。结论

Objective:To explore the clinical diagnostic significance of color Doppler ultrasongraphy in mensuration of hemodynamics of cirrhosis portal system Methods:The color Doppler ultrasongraphy was used to examine the blood flow parmeters of portal system in 22 cases with cirrhosis and comparatively analyzed with the controlled group of 20 healthy persons Results:In cirrhosis cases,the diameter of pylic main trunk was markedly enlarged comparing to the control group,velocity of blood flow decreased,volume of blood flow increased and the summation of volume of blood flow of pylic left right branches was smaller than the volume of blood flow of the pylic main trunk Conclusion:Color Doppler ultrasongraphy has significant clinical values in diagnosis of cirrhosis portal hypertension
