右肝动脉综合征

Right hepatic artery syndrome

右肝动脉综合征是指右肝动脉在与肝外胆管相交而行时,压迫肝外胆管,引起慢性胆管梗阻,严重者,可并发胆管结石、急性胆道感染、梗阻性黄疸等。该症发病率低,缺乏特征性的临床表现,常被误诊为胆管肿瘤或结石。提升认识水平,重视影像检查对胆管狭窄部位和右肝动脉解剖关系的显示,是提升右肝动脉综合征诊断水平的重要前提。治疗方式依病理改变和并发症的程度而定,腹腔镜下右肝动脉松解和胆道探查术是首选和常用的治疗方式。

Right hepatic artery syndrome refers to a syndrome of compression of extrahepatic bile duct by right hepatic artery, resulting in chronic biliary obstruction. In the severe cases, it can be complicated by bile duct stones, acute cholangitis and obstructive jaundice, and so on. This syndrome has a low incidence, lack of characteristic clinical manifestations and is often misdiagnosed as a bile duct tumor or bile duct stone. It is an important prerequisite to improve the recognition level of the syndrome and to pay attention to the imaging examination on the anatomic relationship between the site of bile duct stenosis and the right hepatic artery. The treatment should be based on the degree of pathological changes and complications. Laparoscopic right hepatic artery dissolution and biliary tract exploration are the most commonly preferred treatment methods.
