| 目的 评价彩色多普勒超声对原位肝移植患者术后肝动脉血栓形成的诊断价值。方法 分析和总结6例原位肝移植后肝动脉血栓形成患者的彩色多普勒超声检查资料,6例患者均经手术或造影证实。结果 5例肝门和肝内门静脉周围均没见肝动脉血流信号,其中1例膈下动脉分支伸入肝内形成侧支循环, 另1例术后第3天肝动脉血流信号显示,术后第5天未见肝动脉血流; 6例均见门静脉流速增高;3例肝内见坏死灶;2例肝内胆管轻度扩张;2例Glisson鞘回声增强。结论 彩色多普勒超声对肝移植后肝动脉血栓形成的诊断有重要作用。 |

| Objective To assess the characteristics of hepatic artery thrombosis (HAT) after orthotopic liver transplantation (OLT) with color Doppler ultrasonography (CDUS). Methods The CDUS data of 6 angiographyically or surgically proved cases of HAT after OLT was summarized. Results Five patients showed no hepatic arterial flow around portal vein. Hepatic arterial flow was observed on the third day after OLT but disappeared on the fifth day in a case. A significant increase in velocity of portal vein was observed in all the 6 patients. Collateral circulation established around hepatic artery in one case. Three patients had hepatic parenchymal necrosis. Two cases had contrast echo of Glisson and 2 had lightly dilated intrahepatic biliary duct. Conclusion CDUS has an important value in the diagnosis of HAT after OLT. |
