[目的]观察与分析利用彩色多普勒超声对急性病毒性肝炎(简称急性肝炎)的诊断价值。[方法]观察36例急性肝炎患者彩色多普勒超声下脾脏厚度、胆囊图像的变化,门静脉(PV)、脾静脉(SPV)和肠系膜上静脉(SMV)的内径(D)及血流速度(V),并与36例正常人进行比较。[结果]急性肝炎患者脾脏厚度及胆囊图像变化、门脉系统V与对照组比较差异有统计学意义;肝脏实质回声改变、PV、SPV的D改变无统计学意义。[结论]彩色多普勒超声诊断急性肝炎患者中,其脾脏厚度、胆囊变化及门脉系统V均发生一定的改变,对临床无创性诊断急性肝炎具有一定的指导意义。
[Objective] To observe and analyze the diagnostic value of using color Doppler ultrasound in acute viral hepatitis (acute hepatitis). [Methods] The changes of spleen thickness and gallbladder image in 36 patients with acute hepatitis were observed. The diameter (D) and blood flow velocity (PV), splenic vein (SPV) and superior mesenteric vein (SMV) V), and compared with 36 normal subjects. [Results] The changes of spleen thickness and gallbladder image in patients with acute hepatitis showed that there was significant difference between portal vein system V and control group. The change of liver echogenicity and the change of PV and SPV D were not statistically significant. [Conclusion] Color Doppler ultrasound in the diagnosis of acute hepatitis patients, the spleen thickness, gallbladder changes and portal system V are some changes, clinical noninvasive diagnosis of acute hepatitis has some guidance.
