目的:应用多普勒超声评价经颈静脉肝内门体分流术(TIPS)后分流道内血流动力学变化情况和在术后随访中的临床价值。方法:收治肝硬化行TIPS术患者36例,采用多普勒超声观察术后分流道内血流动力学变化情况。结果:所有患者手术均成功,发生肝性脑病患者2例,分流道功能障碍患者3例;正常支架内血流速度与狭窄支架内血流速相比,差异有统计学意义(P<0.05)。结论:多普勒超声能简单、直观地观察分流道内血流动力学变化情况,是发现分流道功能障碍的有效方法。
Objective: To evaluate the changes of hemodynamics in shunt after transjugular intrahepatic portosystemic shunt (TIPS) with Doppler ultrasound and its clinical value after follow-up. Methods: Totally 36 patients underwent hepatic stenting underwent TIPS. The changes of hemodynamics in the shunt were observed by Doppler echocardiography. Results: All the patients were operated successfully. There were 2 patients with hepatic encephalopathy and 3 patients with diverticular dysfunction. The blood flow velocity in the normal stent was significantly different from that in the stenosis stent (P <0.05) . Conclusion: Doppler ultrasound can observe hemodynamics changes easily and intuitively, and it is an effective method to find out the diversion dysfunction.
