目的探讨彩色多普勒超声(CDFI)在门静脉海绵样变性诊断中的临床应用价值。方法回顾性分析2004年1月至2008年6月39例彩色多普勒超声诊断为门静脉海绵样变性患者的声像图特征,并与手术、CT、血管造影对照。结果彩色多普勒超声诊断符合率100%(39/39)。声像图特征:肝门部正常门脉、胆管结构消失,出现“蜂窝状”无回声区,CDFI显示无回声区内出现红、蓝相间彩色血流信号,脉冲多普勒(PW)示门静脉频谱。结论彩色多普勒超声在门静脉海绵样变性诊断中具有重要的临床应用价值。
Objective To investigate the clinical value of color Doppler ultrasound (CDFI) in the diagnosis of cavernous degeneration of portal vein. Methods The echographic features of 39 cases diagnosed as cavernous degeneration of portal vein by color Doppler sonography were retrospectively analyzed from January 2004 to June 2008 and compared with those of surgery, CT and angiography. Results The diagnostic accuracy of color Doppler ultrasound was 100% (39/39). Echocardiography features: normal portal vein, bile duct structure disappeared, there was “honeycomb ” anechoic area, CDFI showed red, blue and white phase color flow signal in anechoic area, pulse Doppler (PW) Show the portal vein spectrum. Conclusion Color Doppler ultrasound in the diagnosis of cavernous degeneration of portal vein has important clinical value.
