The clinical significance of fetal intra-abdominal umbilical vein varix (FIUVV) remains unclear, and specific obstetric management protocols have not yet been established. The aim of the present report was to demonstrate a case of FIUVV resulting in favorable perinatal outcomes due to our clinical strategies. We suggest close management of cases with a fetal diagnosis of FIUVV, including detection of the venous thrombus, Doppler velocimetry, and continuous fetal heart rate (FHR) monitoring. The timing of delivery is arguable. Despite close fetal monitoring, unexpected acute fetal death occasionally may occur. We believe early delivery is considerable in order to obtain a healthy infant.
