肝移植术后胆道并发症的影像学诊断

目的分析肝移植术后胆道并发症的影像学（ＣＴ、ＭＲＩ、“Ｔ”形管造影）表现。材料与方法回顾性分析了我院７例原位肝移植术后影像学资料，７例均为男性，年龄３３～５０岁，肝硬化病史４～１０年。术后１例行腹ＣＴ平扫，５例行平扫加增强扫描，１例行单纯增强扫描，其中３例作了ＭＲＩ检查。所有病例均行“Ｔ”形管造影。结果胆漏１例；肝内胆管狭窄１例，非吻合口胆总管狭窄１例。结论胆系造影是肝移植术后胆道系统并发症（胆漏、胆管狭窄）诊断的常规方法，ＣＴ及ＭＲＩ扫描可以显示间接征象。

Diagnostic Imaging of Billary Tract Complication after Liver Transplantation

Purpose To analyse CT, MRI and T tube cholangiography findings of binary tract complications after orthotopic liver transplantation. Materials and methods We retrospectively reviewed the postoperative CT, MRI and T tube cholangiography findings of the 7 patients who underwent orthotopic liver transplantation (OLT)in our hospital. All 7 patients are men, ranging in age from 33-50 years. History of cirrohsis were 4-10 years. Postoperation one patient was taken abdominal plain CT scan, five patients were taken plain and enhanced plain CT scan, one patient was taken enhanced plain CT scan, and three patients were taken MRI examination. All 7 patients were perfomed T tube cholangiography. Results Bile leak: one case; nonanastomotic common binary stricture,one case; intrahepatic biliary stricture, one case. Conclusion Cholangiography are routinely used in the postoperative evaluation of patients with binary tract complication. CT and MRI can provid indirectly signs.
