A child with trisomy 21 had altered mental status and hyperammonemia at presentation and was found to have a congenital portosystemic shunt as a result of a congenital abnormality of the portal venous system. Anomalies of the portal venous system leading to portosystemic shunting, although they are infrequent, should be considered in the differential diagnosis of hyperammonemia.
一名21三体综合征患儿在就诊时出现精神状态改变和高氨血症，结果发现其因门静脉系统先天性异常而患有先天性门体分流。导致门体分流的门静脉系统异常虽然不常见，但在高氨血症的鉴别诊断中应予以考虑。
