彩色多普勒超声在肝硬化门脉高压中的临床应用价值

Clinical Value of Color Doppler Ultrasonography in Portal Hypertension of Liver

目的分析彩色多普勒超声对肝硬化门脉高压患者的临床诊断价值。方法方便抽选2015年11月—2017年1月该院接收的68例肝硬化门脉高压患者,将其作实验组;同时选同期68名健康体检者,将其作参照组;对2组均行彩色多普勒超声诊断,比对2组脾静脉、门静脉血流动力学、血流量比值改善情况。结果实验组脾静脉内径值(1.05±0.16)cm,门静脉内径值(1.48±0.18)cm,均优于参照组(0.81±0.21)、(1.21±0.19)cm,差异有统计学意义(P<0.05);实验组血流量比值(0.48±0.08),比参照组(0.27±0.10)高,(P<0.05);实验组脾静脉内径超过1.0 cm、门静脉内径超过1.4 cm患者,重度食管胃底静脉曲张所占比例43.59%、40.54%,均比低于1.0 cm、低于1.4 cm患者所占比例20.69%、12.90%高,(P<0.05)。结论临床对肝硬化门脉高压患者展开专业诊断时,予以彩色多普勒超声诊断,可在准确评估患者脾静脉、门静脉血流动力学水平的基础上,增加血流量比对。

Objective This paper tries to evaluate the clinical value of color Doppler ultrasonography in the diagnosis of portal hypertension in patients with liver cirrhosis.Methods 68 patients with cirrhotic portal hypertension received from November 2015 to January 2017 were conveient selected as the experimental group.68 healthy subjects were selected as the control group.All the two groups underwent color Doppler ultrasonography and were observed at the same time.Compared with the two groups,the ratio of splenic vein,portal vein hemodynamics and blood flow improved condition.Results The diameter of the splenic vein(1.05±0.16)cm and the portal vein diameter(1.48±0.18)cm,were significantly higher than those in the control group(0.81±0.21)cm,(1.21±0.19)cm,with significant difference(P<0.05).The blood flow ratio(0.48±0.08)in the experimental group was higher than that in the control group(0.27±0.10)(P<0.05).In the experimental group,the diameter of the splenic vein was more than 1.0 cm,the portal vein diameter was more than 1.4 cm,the proportion of varicose veins was 43.59%and 40.54%,respectively,which were lower than 1.0 cm,and the proportion of patients with less than 1.4 cm was 20.69%and 12.90%,respectively(P<0.05).Conclusion Color Doppler ultrasonography can be used to diagnose the hemodynamics of splenic vein and portal vein in patients with cirrhotic portal hypertension.The blood flow ratio comparison is increased.
