摘要 目的 :应用多普勒超声检测经颈静脉肝内门体静脉支架分流术(Transjugular intrahepatic portosystemic stentshunt,TIPSS)术后内支架及其血流情况,包括正常、狭窄和闭塞,探讨多普勒超声在TIPSS术后随访中的价值。方法:32例肝硬化门脉高压患者行TIPSS,术后多普勒超声检查86例次,包括支架内的血流、门静脉和脾静脉的血流方向和速度。结果:随访时间为8月~3年,二维超声清晰显示TIPSS内支架的网状回声,彩色多普勒和能量多普勒显示支架内的血流方向,频谱多普勒显示支架内以及门静脉和脾静脉的血流速度。其中5例病人多普勒血流显示支架内狭窄,支架门静脉端和肝静脉端血流速度减慢,支架内狭窄处为高速湍流。门静脉及脾静脉速度明显降低,为门静脉造影所证实。与非狭窄支架组比较,狭窄支架的血流速度测值差异有显著性意义(P〈0.05)。结论:多普勒超声可以方便有效地检测TIPSS术后内支架的血流情况及早期发现分流道的狭窄,是TIPSS术后定期复查和疗效判断的首选方法。
