Four cases of fetal intra-abdominal umbilical vein varix: A single centre's approach to management

Abstract: Fetal intra-abdominal umbilical vein (FIUV) varix is a rare prenatal abnormality characterised by a focal intrahepatic or extrahepatic dilatation of the intra-abdominal portion of the umbilical vein. Usually, it is an isolated finding, but in some cases it can be associated to other fetal anomalies. Thrombosis is a possible complication of FIUV varix and it can lead to poor fetal or neonatal outcome. We describe four consecutive cases of FIUV varix diagnosed in our Unit and managed with low-dose aspirin (LDA) … Show more

“…Otros diagnósticos diferenciales son lesiones quísticas abdominales, como vesícula biliar distendida, quiste mesentérico o duplicación entérica. La evaluación Doppler color detecta el flujo venoso en su interior y permite diferenciarlo de otras estructuras sonolucentes, como quiste de colédoco o del uraco (10) . Además, el trazado espectral también contribuye a confirmar el patrón de flujo venoso dentro de la lesión (2) .…”

“…Las aneuploidías (trisomías 9, 18 y 21), al igual que las triploidías, también pueden estar asociadas al desarrollo de la lesión. Todas estas condiciones justifican la evaluación adicional por estudio del cariotipo neonatal (10)(11)(12) . Aunque la várice intraabdominal de la vena umbilical fetal es poco frecuente, está asociada con alta tasa de mortalidad y debe considerarse su curso clínico.…”

“…Table 2 presents information on sonographic fetal monitoring and (preterm) labor induction due to i-FIUVV. Most study groups performed at least weekly sonographic assessments after 28-32 weeks of gestation, 14,[42][43][44][45] while two did not specify their method and frequency of monitoring. 12,15 Two study groups induced labor in all i-FIUVV subjects at 36-37 weeks of gestation 13,43 while three others based the decision to induce on the presence of turbulent flow, non-reassuring CTG, and/or other obstetrical indications.…”

“…12,15 Two study groups induced labor in all i-FIUVV subjects at 36-37 weeks of gestation 13,43 while three others based the decision to induce on the presence of turbulent flow, non-reassuring CTG, and/or other obstetrical indications. 42,44,46 One study 47 did not induce labor due to i-FIUVV presence. The remaining four studies did not (clearly) specify their indications or timing of induction of labor, 12,15,39,45 or the authors only mentioned that the timing of birth was left at the discretion of the primary caretaker.…”
