彩色多普勒超声在肝硬化门静脉血流动力学检测中的应用

Application Of Color Doppler Ultrasound Detection of Portal Venous Hemo-dynamics on Patients with Liver Cirrhosis

目的探讨彩色多普勒超声在肝硬化门静脉血流动力学检测中的应用效果。方法整群选取2013年7月—2015年12月间来该院就诊的肝硬化患者(观察组)及健康体检者(对照组)各117例,全部给予彩色多普勒超声检查,分析其血流动力学指标的特点。结果观察组DPv(1.35±0.26)cm和Qpv(1247.83±502.35)m L/min均明显高于对照组DPv(1.02±0.19)cm和Qpv(1036.08±372.27)m L/min,而观察组VPv值15.96±6.91)cm/s,明显低于对照组26.01±7.36)cm/s(P<0.05);同时不同Child-Pugh分级间的DPv、VPv及Qpv均差异有统计学意义(P<0.05)。结论彩色多普勒超声可检测出肝硬化患者与健康者门静脉血流动力学的差异,还可检测出不同肝功能分级间不同指标的变化。

Objective To explore the features of portal venous hemodynamics on patients with liver cirrhosis by detection of color Doppler ultrasound. Methods Group selection 117 cases（observation group） with liver cirrhosis and 117 healthy cases（control group）,who came our hospital from July 2013 to December 2015,were selected to give the examination of Color Doppler ultrasound. Analyze the characteristics of hemodynamic indices among them. Results In Observation group, DPv（1.35±0.26）cm and Qpv（1247.83±502.35）m L/min were higher than control group＇s DPv（1.02±0.19）cm and Qpv（1036.08±372.27）m L/min）,while VPv（15.96±6.91）cm/s was obviously lower than control group（26.01±7.36）cm/s.And there are significant differences between Child-Pugh classification and DPv,VPv,Qpv values（P〈0.05）. Conclusion Color Doppler ultrasound can detect the difference of portal venous hemodynamics between cirrhosis patients and healthy subjects and identify the change of every index in different classification of liver function.
