Fetal intraabdominal umbilical vein varix (FIUV) is focal dilatation of the intrabdominalumbilical vein of thefetus. It appears as a round or fusiform cystic structure in thefetal abdomen, which shows continuity with the umbilical vein ongrayscale andcolor Dopplerimaging. The diagnostic criteria include the FIUV varix diameter at least 50% wider than the diameter of the intrahepatic umbilical veinand an intraabdominal umbilical vein diameter exceeding 9 mm orgreater than twostandard deviations above the mean for gestational age. We report three cases, two cases with isolated FIUV and favorable outcome and the third case with FIUV and atrioventricular septal defect, where trisomy 21 (Down syndrome) was diagnosed.
胎儿腹腔内脐静脉瘤样扩张（FIUV）是胎儿腹腔内脐静脉的局限性扩张。它在胎儿腹部表现为圆形或梭形囊性结构，在灰阶和彩色多普勒成像上与脐静脉相连。诊断标准包括FIUV瘤样扩张的直径至少比肝内脐静脉直径宽50%，且腹腔内脐静脉直径超过9mm或比胎龄平均直径高出两个标准差以上。我们报告3例病例，2例为孤立性FIUV且预后良好，第3例为FIUV合并房室间隔缺损，诊断为21三体综合征（唐氏综合征）。
