摘　　要：目的探讨超声对小儿先天性颈内静脉扩张症的诊断价值及超声诊断流程。方法 131例颈内静脉扩张症患儿(病变组),体检健康小儿100例为对照组,分别在平静呼吸状态和哭闹或Valsalva’s试验时记录两侧颈内静脉短轴的最大前后径和左右径,并观察颈内静脉形态特征。结果在平静呼吸状态下,病变组颈内静脉的内径与对照组比较差异无统计学意义(P>0.05)。在Valsalva’s试验时,病变组颈内静脉管腔径线较对照组增大(P<0.05),左右径和前后径平均增加到平静呼吸时的2.47倍和2.42倍,其中最大者分别为5倍和4.18倍;血流在扩张的颈内静脉段呈涡流状,彩色多普勒超声呈五彩镶嵌血流束,频谱多普勒超声可见一过性逆流信号。结论超声是诊断小儿先天性颈内静脉扩张症的首选方法,必要时还需结合其他影像学检查辅助诊断。Objective To investigate the diagnostic value and criteria of ultrasonography in children with congenital internal jugular phlebectasia.Methords One hundred and thirty-one children with congenital internal jugular phlehectasia and 100 healthy children were enrolled. The diameters of internal jugular veins（IJV）at short axis were measured by ultrasonography in eupnea and crying or Valsalva＇s test, and morphological characteristic of IJV was observed. Results In eupnea, there was no significant difference in diameters of IJV between the two groups. In Valsalva＇s test, the diameters of IJV in experimental group were larger than that in control group（P〈0.05）. The transverse and antero-posterior diameter of IJV averagely increased to 2.47 and 2.42 times of eupnea. Blood flow in expanded IJV showed eddy current. Color Doppler ultrasound showed colorful blood flow. Spectrum Doppler ultrasonography showed a transient reverse flow. Conclusion Uhrasonography is a preferred method in the diagnosis of congenital internal jugular phlebectasia. Other imaging examinations may be needed to diagnose the patients who progress worsely.
