A congenitally patent ductus venosus is the rarest form of portosystemic shunt. Although it occurs in the absence of serious parenchymal liver disease, it may be associated with hepatic encephalopathy. This case report describes a 49-year-old man with a patent ductus venosus who presented with recurrent bouts of encephalopathy but few other features of chronic liver disease. Ligation of the shunt was followed by life-threatening complications. The portal venous system must be carefully assessed before closure of a patent ductus venosus is attempted.
先天性静脉导管未闭是门体分流最罕见的形式。虽然它在没有严重实质性肝病的情况下发生，但可能与肝性脑病有关。本病例报告描述了一名49岁患有静脉导管未闭的男性，他反复出现脑病发作，但几乎没有其他慢性肝病的特征。分流结扎后出现了危及生命的并发症。在尝试闭合未闭的静脉导管之前，必须仔细评估门静脉系统。
