Intra-Abdominal Umbilical Vein Varix – A Case Report

AbstractThe incidence of the fetal intra-abdominal umbilical vein varix condition is very rare and has been associated with fetal hydrops, IUGR and still birth A 26-year-old primigravida was referred for routine antenatal scan. The scan at 30 weeks showed an intra-abdominal ovoid structure superior to the fetal bladder. Color flow Doppler revealed venous flow in continuity with the umbilical vein. A diagnosis of umbilical varix was made. The venous flow was present throughout the lesion, suggesting the absence of thrombi. There was no evidence of fetal hydrops. Subsequent scans at regular intervals showed no increase in size of the umbilical varix. The patient had an uneventful elective cesarean section at 39 weeks. Postnatal assessment and a follow-up neonatal cardiac echo scan were normal. Our case supports the new emerging evidence that pregnancy outcome in cases of isolated fetal umbilical vein varix is generally good. Caution must be exercised against unnecessary early induction and costly preterm births
