小儿非肝病性门静脉海绵样变性的能量多普勒超声诊断

Diagnosis of Children Non-hepatopathic CTPV Using CDE

目的:探讨小儿非肝病性门静脉海绵样变性的超声二维声像图特点及能量多普勒血流动力学特征。方法:在二维超声下观察门静脉主干及分支的结构,用能量多普勒观察病变区的血流状态及微血管的充盈情况。结果:肝门部正常门静脉、胆管结构消失,呈蜂窝状无回声区,CDE为明亮红色相互连通的血流图像,脉冲多普勒(PW)示血流信号为门静脉样低速血流频谱。结论:二维超声结合能量多普勒血流显像能为小儿非肝病性门静脉海绵样变性提供有效的诊断依据。

Objective：To investigate the characteristics of 2- D ultrasonography and hemodynamics with CDE in non-hepatopathic CTPV. Methods：The main hepatic vein and its branches were observed with ultrasonography,and the blood flow and the capillary perfusion with CDE. Results：The portal vein and bile duct in porta hepatis disappeared and showed echoless in honeycombe appearance. The rheogram showed bright red imaging of blood which communicated with each other in CDE. The sign of blood flow in porta hepatis was in lower flow rate of spectrum in PW. Conclusion： Ultrasonography combined with CDE provides diagnostic evidence for children non - hepatopathic CTPV.
