Prenatal diagnosis and management of fetal intra-abdominal umbilical vein varix
Journal of family medicine and primary care
Fetal intra-abdominal umbilical vein varix (FIUVV) is a rare pathology and suggests an enlargement of the umbilical vein. Prenatal diagnosis is done through meticulous ultrasound imaging. Management variables are the diameter of varix, presence or absence of turbulent flow, and fetal anomalies. Color and power Doppler ultrasound helps in diagnosis and follow-up and has a critical role in decision-making for intervention. Clinical guidelines for management are not clear. The adverse fetal outcome is usually associated with multiple malformations, turbulent flow, and thrombotic varix. This case study presents the prenatal diagnosis, obstetric management, and neonatal development of a fetus, diagnosed with FIUVV along with a brief review of the literature.
Prenatal diagnosis of fetal intra-abdominal umbilical vein varix: Report of 2 cases
Journal of Clinical Ultrasound, 2008
Fetal intra-abdominal umbilical vein varix (FIUVV) is a focal aneurysmal dilatation of the umbilical vein. Its clinical importance has not yet been clearly established, but it has been reported to be associated with increased fetal death rate (in nearly 44% of cases) and chromosomal abnormalities (in 12% of cases). We report 2 cases of FIUVV diagnosed via sonography in the third trimester. © 2007 Wiley Periodicals, Inc. J Clin Ultrasound, 2008
Isolated Fetal Intra-Abdominal Umbilical Vein Varix
Journal of Ultrasound in Medicine, 2011
fetal intra-abdominal umbilical vein varix is defined by an index portion of the umbilical vein that is at least 50% wider than the nondilated portion or dilatation of 9 mm or greater. 1 Others have defined it as a measurement that is more than 2 SDs above the mean for gestational age. The first description of a fetal intra-abdominal umbilical vein varix was of several cases with grave fetal outcomes, 3 and most of the initial studies were case reports with mortality rates of up to 43%. For many years, cases of isolated fetal intra-abdominal umbilical vein varices have not been differentiated from cases associated with other fetal structural or chromosomal abnormalities. Approximately 150 cases of isolated fetal intra-abdominal umbilical vein varices have been described in the last 3 decades. In recent reports, the neonatal prognosis was found to be substantially better than that reported in older studies. In this series, we describe our experience with cases of an isolated fetal intra-abdominal umbilical vein varix. This series adds to other recent studies reporting rather reassuring outcomes of fetuses with fetal intra-abdominal umbilical vein varices. This information affects fetal surveillance and preterm labor induction policies in these cases.
Fetal Intra-abdominal Umbilical Vein Varix: A Case Report and Literature Review
Gynecology & Obstetrics, 2016
Fetal intra-abdominal umbilical vein (FIUV) varix is a rare malformation of the umbilical cord. This is a critical situation due to discrepancies in outcomes varying from normal to high rates of complications and fetal mortalities. We report the observation of a FIUVV vein diagnosed precociously at 22 weeks with a quiet increasing of the diameter by 31 weeks. The outcome was favourable and close monitoring after birth showed no anomalies. Despite a good prognosis it seems that a close monitoring is essential in antenatal period.

ABSTRACT – The 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 KEYWORDS - Fetal umbilical vein varix, Ultrasonography, Pregnancy outcome
