Fetal intra‐abdominal umbilical vein varix (IUVV) is one of the rare anomalies of the umbilical vessels that simulate a cystic structure but with a vascular nature. IUVV usually drains into IVC through ductus venosus (DV), with evidence of an increase in the cardiac preload in most cases. In the current report, we present a fetus with congenital heart disease; however, the association of large IUVV with DV agenesis and direct drainage into the heart resulted in a high output fetal heart failure.

“…73 The latter two criteria are gestational age-dependent and therefore account for The main complication of UV varix is thrombosis, which was found in 2 of 167 isolated cases (1.2% or 1 in 83), 76 and has been associated with fetal death. 74 However, most cases are associated with a normal pregnancy outcome, 74,77 especially those with no associated findings. In our cohort, 19 cases of UV varix were diagnosed, for a prevalence of 1 in 898 fetuses.…”

Visualization of the axial plane of the fetal abdomen is mandatory to obtain abdominal biometry in the assessment of fetal growth in the second and third trimesters.The main anatomic landmarks that must be identified in this view include the fetal stomach and the intrahepatic portion of the umbilical vein, which are easily identifiable as they appear anechoic on ultrasound. The gallbladder is the other prominent anechoic structure in this plane. Focused study of the morphological characteristics of, and spatial relationship among, these three anechoic spaces is a simple technique to detect anomalies involving fetal upper abdominal organs. In this review, the sonographic features of those conditions that can be detected using this technique, which was termed the Fetal Examination of the Anechoic Spaces of upper abdomen Technique (FEAST), are classified and illustrated.

“…A value greater than 9 mm or 1.5-fold dilatation, compared to the normal adjacent segment of the umbilical cord, is required for the diagnosis [ 97 ]. The main complication is the thrombosis of the varix with hydrops fetalis as a direct consequence, but the recent multicenter cohort study of Novoa et al sustains the association with chromosomal and/or anatomical abnormalities in 20% of cases [ 98 ]. Antenatal ultrasound reveals a cystic/elongated dilatation in close relation to the umbilical artery with non-pulsatile flow on a Doppler exam ( Figure 11 and Figure S2 ).…”

Umbilical cord abnormalities are not rare, and are often associated with structural or chromosomal abnormalities, fetal intrauterine growth restriction, and poor pregnancy outcomes; the latter can be a result of prematurity, placentation deficiency or, implicitly, an increased index of cesarean delivery due to the presence of fetal distress, higher admission to neonatal intensive care, and increased prenatal mortality rates. Even if the incidence of velamentous insertion, vasa praevia and umbilical knots is low, these pathologies increase the fetal morbidity and mortality prenatally and intrapartum. There is a vast heterogeneity among societies’ guidelines regarding the umbilical cord examination. We consider the mandatory introduction of placental cord insertion examination in the first and second trimester to practice guidelines for fetal ultrasound scans. Moreover, during the mid-trimester scan, we recommend a transvaginal ultrasound and color Doppler assessment of the internal cervical os for low-lying placentas, marginal or velamentous cord insertion, and the evaluation of umbilical cord entanglement between the insertion sites whenever it is incidentally found. Based on the pathological description and the neonatal outcome reported for each entity, we conclude our descriptive review by establishing a new, clinically relevant classification of these umbilical cord anomalies.
