Umbilical vein varices are rare umbilical cord anomalies that typically occur intra-abdominally. Extra-abdominal umbilical vein varices are exceedingly rare and usually diagnosed postnatally on gross pathologic examination. Umbilical vein varices have been associated with increased risk of fetal anemia, cardiac abnormalities, and intrauterine fetal demise. This case report discusses a patient who presented with a massive extra-abdominal umbilical vein varix, whose infant was ultimately delivered due to fetal distress and died in the neonatal period. This report also discusses associated fetal conditions and guidelines for antenatal testing and surveillance of known umbilical vein varices.
脐静脉静脉瘤是罕见的脐带血管畸形，通常发生在腹腔内。腹腔外脐静脉静脉瘤极为罕见，通常在产后大体病理检查时诊断。脐静脉静脉瘤与胎儿贫血、心脏异常和宫内胎儿死亡的风险增加有关。本病例报告讨论了一位患者，其表现为巨大的腹腔外脐静脉静脉瘤，由于胎儿窘迫，最终分娩，新生儿期死亡。本报告还讨论了相关的胎儿情况以及对已知脐静脉静脉瘤的产前检查和监测的指南。
