Our goal was to assess the state of the portal vein in cirrhotic patients treated with a portacaval shunt associated with an arterialization of the portal vein.
We reviewed the follow-up CT of 23 patients treated by portacaval shunt with arterialization of the portal vein.
Five patients demonstrated an aneurysm of the portal vein. Follow-up studies revealed progression of the aneurysm and development of a mural thrombosis in four patients. The thrombosed portal vein was calcified in three patients. One patient demonstrated a dilatation of the saphenous vein graft in addition to the portal vein aneurysm. Only one of the five patients was symptomatic, presenting with ascites, dilatation of intrahepatic biliary ducts, and jaundice secondary to the compression of hilar structures by the huge portal vein.
Aneurysm of the portal vein following portacaval shunt associated with arterialization of the portal vein is not a rare complication.
我们的目标是评估接受门静脉动脉化联合门腔分流术治疗的肝硬化患者的门静脉状态。
我们回顾了23例接受门静脉动脉化联合门腔分流术治疗患者的随访CT。
5例患者出现门静脉瘤。随访研究显示4例患者的动脉瘤进展并出现壁内血栓形成。3例患者血栓形成的门静脉发生钙化。1例患者除门静脉瘤外还出现大隐静脉移植物扩张。5例患者中仅1例有症状，表现为腹水、肝内胆管扩张以及因巨大门静脉压迫肝门结构继发黄疸。
门静脉动脉化联合门腔分流术后门静脉瘤并非罕见并发症。
