目的探讨肝脏血管周围晕环征( PVL)的CT表现及相关临床意义. 方法回顾性分析18例肝脏PVL的CT及临床资料,总结其CT表现、分布特点、相关病理基础及疾病类型. 结果肝脏CT增强扫描中,PVL表现为肝脏门静脉左右支及其分支周围和/或第二肝门区下腔静脉周围"双轨道征"或"日晕征". 18例PVL中,位于门静脉主干及左右分支者8例,门静脉中远段者4例,第二肝门区下腔静脉周围者2例,同时出现上述两种或3种征象者4例. 疾病类型中,慢性活动性肝炎7例,肝硬化4例,心功能不全3例,外伤后2例,食管癌化疗后1例,长期大量饮酒者1例. 结论肝脏PVL的CT增强表现和分布特点具有特异性,是反映肝内淋巴动力学和血液动力学异常的重要指标.

Objective To find out the clinical significance of liver perivascular lucency ( PVL) via CT tech-nology .Methods Eighteen cases were retrospective analyzed ,which include liver PVL analysis in CT repots;related pa-tients'clinical manifestations .It tried to find out typical display of PVL in liver CT images;review hepatic PVL structures and distuibutions:and explain pathological features and clinical manifestations of these cases .Results With Hepatic En-hancement technology of computerized tomography (CT),PVL images,called "dual-track"or "solar halo",are found a-round portal vein ,portal vein left and fight branch ,and their small branches areas;include or only show in the combina-tion area of 2nd liver portal vein and inferior caval vein .Among 18 cases,8 cases have PVL which are around portal vein,its left and right branches area;4 cases have PVL which are around middle and distal parts of portal vein;2 cases have PVL which are around hepatic 2 nd portal vein and inferior cacal vein area;4 other cases have 2 or 3 different PVL displays which are discussed above .In the diagnosis of these 18 cases,7 cases have chronic hepatitis;4 cases have hepa-tocirrhosis;3 cases have cardiac in sufficiency;2 cases have trauma syndrome;1 case is post-chemo-therapy patient with esophagus cancer;and 1 case is alcoholic .Conclusion PVL and its distribution in liver enhanced CT are specificity which are important anomaly indic ators in hepatic lymph liquid dynamic and hepatic hemodynamic .
