超声造影在儿童肝移植术后肝动脉血栓中的临床应用价值

Clinical application value of contrast-enhanced ultrasound in hepatic artery thrombosis after pediatric liver transplantation

    摘要
  • 摘要:
      目的  探讨超声造影（CEUS）在儿童肝移植术后肝动脉血栓（HAT）中的临床应用价值。
      方法  回顾性分析126例儿童肝移植受者的临床资料，总结儿童肝移植术后HAT发生情况，比较HAT的彩色多普勒超声和CEUS表现。
      结果  彩色多普勒超声高度怀疑HAT者17例，CEUS诊断HAT者9例，其中CEUS提示HAT的9例受者均经CT血管造影（CTA）或手术证实诊断。HAT的CEUS表现为肝动脉在动脉期乃至门静脉期在门静脉周围未见显影，4例HAT患者发生肝细胞坏死，CEUS表现为肝内造影剂无灌注。
      结论  CEUS在儿童肝移植术后HAT的诊断中有较高的临床应用价值，与传统CTA相比优势明显，可以在临床广泛推广。

     

    Abstract:
      Objective  To investigate the clinical application value of contrast-enhanced ultrasound (CEUS) in hepatic artery thrombosis (HAT) after pediatric liver transplantation.
      Methods  Clinical data of 126 pediatric recipients undergoing liver transplantation were retrospectively analyzed. The incidence of HAT after pediatric liver transplantation was summarized. Color Doppler ultrasound and CEUS manifestations of HAT were compared.
      Results  According to color Doppler ultrasound, 17 cases were highly suspected with HAT. Nine cases were highly suspected with HAT by CEUS, who were subsequently confirmed by CT angiography (CTA) or surgery. CEUS manifestations of HAT showed that hepatic artery was not seen surrounding the portal vein during the arterial phase or even portal venous phase. Hepatocyte necrosis occurred in 4 patients with HAT, and no perfusion of intrahepatic contrast agent was observed on CEUS.
      Conclusions  CEUS yields high clinical application value in the diagnosis of HAT after pediatric liver transplantation. It has significant advantages compared with traditional CTA, which could be widely applied in clinical practice.
