Abstract:
Objective TostudythevalueofordinarycolorDopplerflowimaging(CDFI)inthe diagnosis of hepatic artery thrombosis (HAT)in early stage after pediatric liver transplantation (PLT).Methods Clinicaldataof55childrenundergoingPLTintheGeneralHospitalofChinesePeople'sArmed Police Forces from April 2005 to May 2014 were analyzed retrospectively. Conventional hemodynamic monitoring was performed in all cases in the early stage after operation by CDFI. No intrahepatic arterial blood flow signal was observed by CDFI multi-angle examination and HAT was suspected. Computed tomography angiography (CTA)and surgical exploration were performed in the suspected HAT patients. The sensitivity and specificityofordinaryCDFIindiagnosingHATwerecalculatedbyChissstatisticalsoftware.Results Among the 55 PLT recipients,3 cases were suspected as HAT by CDFI,including 2 cases of HAT in the main hepatic artery,1 cases of HAT in the right hepatic artery. All cases were confirmed by CTA or surgical exploration.The incidence of HAT was 5% (3/55 ). The sensitivity and the specificity of CDFI in diagnosing HAT after PLTwereboth1.0,andfalsepositiveratewas0.Conclusions OrdinaryCDFIisthepreferredandmain method for hemodynamic examination after PLT. The experienced sonographer for transplantation can improve the accuracy in diagnosing HAT.
