We describe five cases of dilation or varix of the umbilical portion of the left portal vein appearing as a fetal intra-abdominal cyst. Doppler or color flow examination, or both, indicated umbilical venous flow within the cystic area in each case. Only one fetus exhibited transient cardiomegaly, which resolved before birth. This fetus was the only one discovered to have the varix as early as the second trimester. All five infants were delivered at term without sequelae.
我们描述了5例表现为胎儿腹腔内囊肿的左门静脉脐部扩张或静脉曲张病例。多普勒或彩色血流检查，或两者均显示，每例病例的囊性区域内均有脐静脉血流。只有1例胎儿出现短暂性心脏肥大，在出生前消退。该胎儿是唯一早在孕中期就发现有静脉曲张的病例。所有5例婴儿均足月分娩，无后遗症。
