摘　　要：目的描述肝脏血管周围晕征(PVL)的病理机制和MRI表现,探讨其与在同肝脏疾病的出现情况,并评价PVL的临床意义。方法回顾性分析2019年1月至2020年1月九江市第三人民医院收治的197例肝脏相关疾病患者为研究对象,按疾病种类分为慢性乙型肝炎组(111例)、肝硬化组(57例)、肝脏肿瘤组(29例)。观察三组患者PVL的MRI的表现,研究患者上腹部MRI平扫及增强的影像资料,分析不同肝脏疾病及其不同程度的PVL情况。结果慢性乙型肝炎患者的PVL检出率为32.4%,肝肿瘤患者的PVL检出率为31.0%,肝硬化患者的PVL检出率为40.4%。肝硬化患者PVL的出现率未随着肝硬化分级评分增加而变化(P>0.05)。肝门梗阻患者的PVL出现率高于肝门区未受到侵犯的患者,差异有统计学意义(P<0.05)。结论PVL的MRI分布和表现在不同肝脏疾病中,有相应的特征性,对于慢性乙型肝炎疾病严重程度和预后评价,以及肝肿瘤是否侵犯肝门区的诊断有参考价值。Objective To describe the pathological mechanism and MRI findings of PVL,discuss its association with the occurrence of the same liver diseases,and evaluate the clinical significance of PVL.Methods A total of 197 patients with liver-related diseases admitted to the Third People's Hospital of Jiujiang from January 2019 to January 2020 were retro-spectively analyzed,and according to the disease type,they were divided into chronic hepatitis B group(11l cases),cirrhosis group(57 cases),and liver tumor group(29 cases).The MRI manifestations of PVL in the three groups were observed,and the MRI plain scan and enhanced image data of the upper abdomen of the patients were studied,and different liver diseases and different levels of PVL were analyzed.Results The PVL detection rate was 32.4%in patients with chronic hepatitis B,31.0%in patients with liver tumor,and 40.4%in patients with cirrhosis.The incidence of PVL in patients with cirrhosis did not change with the increase of cirrhosis grading score(P>0.05).The incidence of PVL in patients with hilar obstruction was higher than that in patients with uninvaded hilar area,and the difference was statistically significant(P<0.05).Con-clusion The MRI distribution and manifestations of PVL in different liver diseases have corresponding characteristics,which has reference value for the evaluation of the severity and prognosis of chronic hepatitis B disease,as well as the diagnosis of liver tumor invading the hepatic portal region.
