目的应用彩色多普勒超声观察急性病毒性肝炎患者病程发展、转归过程中,肝脏门静脉、脾静脉血管内径的变化程度、脾脏厚度及肝脏实质回声的改变情况,以及急性肝炎门静脉系统血流动力学的改变,从而协助临床提高无创性诊断急性肝炎的准确性。方法1.本文观察了34例病理诊断为急性肝炎的患者在转氨酶重度升高时,门静脉(PV)、脾静脉(SV)的内径、脾脏(SP)厚度及肝脏实质回声的变化,并与转氨酶降至轻度升高时以上各值进行比较;2.急性肝炎发病期门静脉(PV)、门静脉右支(RPV)、脾静脉(SV)的内径(D)、血流速度、门静脉血流量(Q),并与34例除外肝脏及心、血管显性病变的正常人进行比较。结果1.随着急性肝炎病程的发展,脾脏厚度有显著性差异,门、脾静脉内径的改变没有统计学意义;2.急性肝炎患者门脉系统各血管内径与对照组没有显著差异,血流速度和门静脉血流量有显著差异。结论通过本文观察认为急性肝炎在发病过程中,肝脏实质回声、脾脏厚度及门脉系统血流速度、血流量均发生一定的改变,这对临床无创性诊断急肝具有一定的指导意。
Objective To observe the changes of the diameter of hepatic portal vein and splenic vein, the changes of the thickness of the spleen and the echogenicity of the liver, and the portal hemodynamics of acute hepatitis by color Doppler ultrasonography. Learning to change, so as to help clinically improve the accuracy of noninvasive diagnosis of acute hepatitis. In this study, 34 patients with pathologically diagnosed acute hepatitis were enrolled in this study. The changes of portal vein (PV), splenic vein (SV) diameter, spleen (SP) (PV), right ventricle (RPV), splenic vein (SV) diameter (D), blood flow velocity, portal vein blood flow ( Q), and compared with 34 cases of normal except for the liver and heart, vascular lesions. With the development of the course of acute hepatitis, the thickness of spleen has significant difference, and the change of the diameter of portal vein and splenic vein has no statistical significance.2. There is no significant difference between the inner diameter of portal system and the control group There was a significant difference in velocity and portal vein blood flow. Conclusions Through the observation of this paper, acute encephalopathy in the pathogenesis of the process, the liver echoes, spleen thickness and portal system blood flow velocity, blood flow were some changes, which non-invasive clinical diagnosis of acute liver injury has some guidance.
