摘要
目的探讨超声造影在肝移植后肝动脉栓塞诊断中的应用价值。方法对475例肝移植受者于术后常规进行肝动脉彩色多普勒超声检查，对11例怀疑肝动脉栓塞患者进行超声造影检查。结果11例患者超声造影均与血管造影或CT血管成像检查结果一致。11例可疑肝动脉栓塞患者中，超声造影明确诊断肝动脉栓塞6例，其中3例伴肝内梗死灶形成。另5例未栓塞患者肝动脉直径纤细，其中3例合并重度脂肪肝。结论超声造影诊断肝动脉栓塞的准确性与血管造影或CT血管成像一致，具有重要的临床应用价值。
Objective To discuss the application value of contrast-enhanced ultrasound（CEUS） in diagnosis of hepatic artery thrombosis（HAT） after liver transplantation. Methods Four hundred and seventy-five liver transplantation patients were performed routine exam by color Doppler ultrasound, 11 patients suspected of HAT were examined by CEUS. Results All cases were confirmed by DSA or CTA. Of them,6 cases were thrombotic by CEUS,and 3 cases out of the 6 cases HAT were founded infarction. The other 5 cases were nonthrombotic,but the diameter of hepatic artery showed narrow,3 patients were accompanied by severe fatty liver. Conclusions CEUS is equally effective as DSA or CTA in diagnosing HAT after liver transplantation.
