摘    要:目的:应用彩色多普勒血流显像(CDFI)评价原位肝移植(OLT)患者的肝血流动力学的改变。方法:85例OLT患者,于术前、术中、术后应用CDFI测定肝总血流量(TLBF)、血流灌注指数(DPI)、门静脉充血指数(PCI)、阻力比(RR)等血流参数,并与30例正常人对照。结果:①OLT患者术后七天之内动脉峰值流速明显低于正常对照组(P<0.01);②术后七天之内门静脉平均流速略高于正常对照组(P<0.05);③其它各项血流动力学参数与正常对照组无显著性差异(P>0.05);④CDFI对OLT术后肝动脉(HA)狭窄、门静脉(PV)、腔静脉(IVC)血栓及胆道并发症可做出较为特异性的诊断。结论:CDFI对OLT术前患者的筛选、术后血流动力学的监测及并发症的早期诊断和鉴别诊断提供重要的依据。

Abstract:Objective:To evaluate the changes of hepatic hemodynamics of 85 cases with orthotopic liver transplantation(OLT)by colour Doppler flow imaging(CDFI).Methods:To measure the total liver blood flow(TLBF),Doppler perfusion index(DPI),Portal congestive index(PCI),and resistance ratio index(RR)of the OLT and 30 healthy persons as the controls by CDFI.Results:1)The peak velocity in the hepatic artery(HA)of the patients was obviously lower than that of the controls within 7 days after the operation(P<0.01);2)The mean velocity of portal vein(PV)was higher than that of the controls within 7 days ofter the operation(P<0.05).3)As to all the other parameters of hemodynamics,there were no significant differences between the patients and the controls.4)CDFI could help to diagnose the complications of OLT specifically,especially HA strictness,Portal vein and inferior vena cava thrombi and biliary duct complications.Conclusions:CDFI can provide main bases for sifting liver transplantation patients before operation,monitor hemodynamics and diagnose complications in the early stage after operation.
Keywords:Liver transplantation  Color Doppler flow imaging  Hemodynamics
