目的探讨彩色多普勒超声检测肝硬化患者门静脉血流动力学的临床价值。方法选取60例肝硬化患者作为研究组,另选取60例健康体检者作为对照组,彩色多普勒超声检测受检者门静脉血流动力学,观察门静脉的内径(DPv)、血流速度(VPv)及血流量(QPv),并观察不同的肝功能的childPugh分级(患者依此分为A、B、C三级)和检测结果的相关性。结果对照组的DPv及QPv均低于研究组,VPv高于研究组,差异均具有统计学意义(P<0.05);DPv随着肝功能分级程度增加呈增宽趋势,但各级间比较差异无统计学意义(P>0.05);VPv随着肝功能分级程度增加而减小,但A、B与C级间比较差异具有统计学意义(P<0.05);QPv随着肝功能分级程度增加而减少,A、B级间比较差异无统计学意义(P>0.05),C级和A、B级比较差异具有统计学意义(P<0.05)。结论彩色多普勒超声检测肝硬化患者门静脉血流动力学是一种良好的检测方法 ,利于临床准确判断肝硬化的进展状况,值得临床推广。
Objective To investigate the clinical value of color Doppler ultrasonography in detecting portal vein hemodynamics in patients with liver cirrhosis. Methods Sixty patients with cirrhosis were selected as the study group. Sixty healthy subjects were selected as the control group. The portal hemodynamics of the subjects were detected by color Doppler sonography. The diameters of portal vein (DPv), blood flow velocity (VPv) ) And blood flow (QPv), and observed the different liver function childPugh classification (patients were divided into A, B, C three) and the correlation between test results. Results The DPv and QPv of the control group were lower than those of the study group, and the VPv of the control group was higher than that of the study group (P <0.05). DPv tended to broaden with the degree of liver function grading increased, (P> 0.05). VPv decreased with the grading of liver function, but there was significant difference between A, B and C (P <0.05). With the increase of liver function grading (P <0.05). There was no significant difference between A and B grades (P> 0.05). There was significant difference between C grade and A grade and B grade (P <0.05). Conclusion The color Doppler ultrasound examination of portal vein hemodynamics in patients with cirrhosis is a good detection method, which is conducive to accurately determine the clinical status of cirrhosis, which is worthy of clinical promotion.
