肝移植术后肝脏淋巴回流淤滞的影像学特征

目的:分析肝移植术后病人肝脏淋巴回流淤滞(intrahepatic lymphatic stasis,IHLS)的计算机断层扫描(Computed Tomography,CT)及磁共振(Magnetic Resonance Imaging,MRI)影像学特征。方法:回顾性收集我院自2004~2012年肝移植术后病人66例,分析其术后CT及MRI图像,对IHLS的阳性次数、持续时间及其影像学特征进行观察分析。结果:66病人中IHLS病人22例。肝移植术后IHLS的直接征象为血管周围项圈征(perivacular collar,PC),CT和MRI可清晰显示且可根据PC的部位分型。结论:肝移植术后IHLS的CT及MRI具有特定的影像学特征,对其识别具有一定的临床意义。

Image Characteristics of Intrahepatic Lymphatic Stasis in Patients after Liver Transplantation

Objective： To study computed tomography （CT） and magnetic resonance imaging （MRI） characteristics of intrahepatic lymphatic stasis （IHLS） in patients after liver transplantation. Methods： 66 patients with liver transplantation whom performed CT and/or MRI seaning collected retrospectively in our hospital from 2004 to 2012 year. Then number, duration, of IHLS, CT and MRI characteristics of IHLS were analyzed after review the CT and MRI data. Results： Of 66 cases with liver transplantation, there was 22 cases with IHLS which displayed called direct Sign called perivaseular collar （PC） after operation. CT and MRI modality can not only show the IHLS clearly but also apply to classification of IHLS according the site of PC. Conclusions： IHLS after liver transplantation has its CT and MRI characteristics and to read it rightly has clinical significance to some extent.
