- Abstract
Background: Progress in echographic techniques, particularly, high-resolution echography and color Doppler, as well increased depth of knowledge and systematization in fetal anatomy exploration, are the main factors responsible for the increased number of cardiovascular anomalies diagnosed prenatally. Objective: To describe the sonographic findings and perinatal outcomes in cases with prenatal ultrasound diagnosis of intra-abdominal umbilical vein varix. Material and methods: A descriptive and retrospective study of cases with prenatal ultrasound diagnosis of umbilical vein varix. The diagnosis is performed at the level of the abdominal circumference when the diameter of the vessel is above the established parameters for a certain gestational age. Variables concerning maternal-fetal features, ultrasound findings and perinatal outcomes of affected cases are described. Results: From August 2008 to August 2012, 14 cases of intra-abdominal umbilical vein varix were diagnosed in our center with a mean gestational age at diagnosis of 29 weeks. Of the 14 cases, 35% had associated anomalies, mostly cardiovascular anomalies. No chromosomal defects were detected. Perinatal outcomes in newborns were favorable, with mean gestational age at delivery of 38 weeks. Only one case of monochorionic-monoamniotic twin pregnancy required preterm elective termination secondary to a twin-to-twin transfusion syndrome. Conclusion: Prenatal diagnosis of intra-abdominal umbilical vein varix should be followed by further studies given its possible association with other anomalies, chromosomal defects and cases of stillbirth. However, isolated cases of umbilical vein varix, representing a majority, often evolve favorably with few complications.
