Aneurysmal dilatation of the portal vein (ADPV) is a rare cause of portal hypertension. We described a case of ADPV in a female patient who presented with ascites. Imaging studies revealed tortuosity and dilatation of the main portal vein with turbulent flow. Endoscopy revealed oesophageal varices. A liver biopsy showed no abnormalities in liver histology. This is the first case of ascites as a complication of ADPV in the absence of liver cirrhosis, arteriovenous fistula or documented portal vein thrombosis. Hyperdynamic circulation and increased portal vein flow could be implicated in the pathogenesis of ascites in this setting.
门静脉瘤样扩张（ADPV）是门静脉高压的罕见病因。我们描述了一例患有腹水的女性ADPV病例。影像学检查显示门静脉主干迂曲、扩张，血流紊乱。内镜检查发现食管静脉曲张。肝活检显示肝脏组织学无异常。这是首例在无肝硬化、动静脉瘘或门静脉血栓形成记录的情况下，腹水作为ADPV并发症的病例。高动力循环和门静脉血流增加可能与这种情况下腹水的发病机制有关。
