门静脉属支超声影像预测血吸虫肝硬化的临床价值

Clinical value of the ultrasonography on portal vein branch in the prediction of schistosoma cirrhosis

目的探讨超声测量门静脉主干内径(Dpv)与肠系膜上静脉内径(Dsmv)增宽率在预测血吸虫肝硬化中的临床价值。方法选取血吸虫肝硬化患者102例(血吸虫肝硬化组)、乙肝肝硬化患者40例(乙型肝硬化组)及体检健康成人150例(正常对照组),检测各组Dpv及其属支的内径和门静脉流速及流量比例。结果血吸虫肝硬化组Dpv增宽率、Dsmv增宽率分别为39.2%、92.15%;乙型肝硬化组Dpv增宽率、Dsmv增宽率分别均为95.0%;各内径与正常对照组比较差异均有统计学意义;两组Dpv增宽率比较差异有统计学意义(P<0.01);血吸虫肝硬化组门静脉流速低于乙肝肝硬化组和正常对照组,差异均有统计学意义(P<0.01)。结论门静脉的属支肠系膜上静脉内径变化可预测血吸虫肝硬化,而且对其他原因引起的门脉高压也有临床参考价值。

Objective To discuss the clinical value of broadening rates between portal vein trunk diameter （Dpv） and superior mesenteric vein diameter （Dsmv） in schistosoma cirrhosis as determined by ultrasouography. Methods One hundred and two patients with schistosoma cirrhosis, 40 patients with hepatitis B liver cirrhosi and 150 healthy controls were enrolled in this study. The inner diameters of Dpv and Dsmv, the ratio of blood flow velocity and volume in portal vein in all groups were measured. Results The broadening rates of Dpv and Dsmv in schistosoma cirrhosis group were 39.2% and 92.15% ,respectively.Both the broadening rates of Dpv and Dsmv in hepatitis B liver cirrhosi group were 95.0%. Statistical difference was found between these two groups. The flow velocity of portal vein in schistosoma cirrhosis group was lower than that in the other two groups （P〈0.01）. Conclusion The change of superior mesenteric vein diameter determined by uhrasonography can predict schistosoma cirrhosis and has clinical reference value for portal hypertension caused by other reasons.
