摘要
目的探讨彩色多普勒超声对门静脉海绵样变性的诊断价值。方法应用彩色多普勒超声对12例门静脉海绵样变的声像图进行观察和分析。结果12例门静脉海绵样变性,全部经CT及动脉间接门静脉造影证实,其中5例为原发性,肝脏损害轻微,7例为继发性,肝脏损害严重。门静脉海绵样变性二维超声显像肝门区结构紊乱,呈蜂窝状或网格状无回声区;彩色多普勒呈红蓝相间彩色血流信号;脉冲多普勒在蜂窝状或网格状无回声区显示门静脉样血流频谱。结论彩色多普勒超声具有无创性、无放射性、简便、实时的优点,可准确地对门静脉海绵样变性做出诊断。
Objective To investigate diagnostic value of cavernous transformation of portal vein (CT- PV) on color Doppler ultrasonography. Methods 12 cases of CTPV were examined with color Doppler ultrasonography. Results 12 cases of CTPV, 5 congenital, 7 postnatal, confirmed by CT or DSA. 2D ultrasound showed structural confusion fluid dark areas and network topology of the porta hepatic, CDFI showed alternating red and blue color Doppler signal. Color Doppler flow spectra showed images of smooth continuous bands in the honeycomb or snaky black areas. Conclusion Color Doppler ultrasonography is non-invasive, non-radioactive, simple and can accurately make diagnosis.
