| 目的 应用MRI扫描成像技术和血管成像方法对肝移植进行术前综合评价,为肝移植手术方案的制定提供依据。方法 对拟行肝移植的29例患者进行MRI成像、肝胰胆管水成像,肝脏体积测量和动态3D血管成像,处理和分析成像结果,以明确肝脏病变性质与范围,病肝体积以及肝脏动静脉及门静脉情况。结果 29例肝移植患者中肝硬化10例,肝恶性肿瘤15例,慢性活动性肝炎2例,布加综合征1例,多囊肝1例。出现肝动脉变异5例,其中2例肝动脉起自肠系膜上动脉,2例起自腹腔干,1例起自胃左动脉。门静脉栓子6例,其中癌栓5例,门静脉海绵样变性1例,1支或2支肝静脉栓塞7例,肝体积明显缩小5例。结论 应用正确的MRI扫描方法可充分显示肝脏病变的范围与性质,明确肝脏体积,采用动态3D血管成像方法可明确显示肝动脉起源,门静脉有无栓子,肝静脉是否通畅,为肝移植术前手术方案的制定提供依据。 |

| Objective To investigate synthetical evaluation of pre-operation of liver transplantation with MRI scanning technology and vessel imaging methods,and offer message of operation project.Methods Twenty-nine cases of liver transplantation were scanned by MRI,MR cholangio-pancreatography (MRCP),volume measure,dynamic contrast enhanced three-dimensional magnetic resonance angiography (DEC 3D MRA) and imaging were analyzed to make explicit property and extension of liver disease,volume and thing of liver artery,vein and portal vein.Results There were 10 hepatocirrhosis,15 liver malignancies,2 chronic activity hepatitis,1 Budd-Chiari syndrome (BCS),1 polycystic liver.There were 5 cases of variation of hepatic artery,and among them 2 cases came from superior mesenteric artery,2 cases from celiac truncus and one from gastric sinistral artery.There were 6 cases portal vein embolus,and among them 5 cancerous embolus,1 portal vein spongy degeneration.One or two hepatic veins had been embolized in 7 cases,liver volume reduced obviously in 5 cases.Conclusion Proper MRI methods will show range and property of hepatic disease fully.DEC 3D MRA can display hepatic artery origin,portal vein embolus or not,hepatic vein flow or not clearly,and it offers message for pre-operation scheme of liver transplantation. |
