“…The application of high-resolution and color Doppler ultrasound has enabled the prenatal investigation of the fetal venous system which has been done intensively during the past few years [1][2][3][4][5][6]. Different types of abnormalities have been described (persistence of the right umbilical vein, umbilical vein varix, ductus venosus agenesis, anomalous course or outlet of the umbilical vein, etc.…”

Objective: To evaluate sonographic appearance, natural history, and neonatal outcome of fetal venous anomalies. Methods: We performed an observational study, including all fetuses affected by abnormalities of the venous system diagnosed by ultrasound during the prenatal period. Results: 26 fetuses were identified. Other malformations were present in 5 cases (19.2%), 1 fetus had trisomy 21, and 1 fetus had intrauterine growth retardation (IUGR). Twenty-five pregnancies ended in liveborn infants, and there was 1 case of unexplained intrauterine death in the fetus with IUGR affected by varix of the umbilical vein. Conclusions: Fetal venous anomalies are very rare and may be associated with fetal malformations or IUGR. Conservative management appears to be an adequate medical practice in the absence of other fetal problems, but in the presence of a varix of the umbilical vein, serial follow-up scans are needed to exclude the onset of hydrops or thrombosis of the varix.

“…Presentation has ranged from stillborn with multiple congenital anomalies [9] to normal term delivery with no associated abnormalities [10][11][12]. On the other hand, persistent right umbilical vein may occur as frequently as 1 in 500 live births [13]. In this situation, the left umbilical vein involutes but the right umbilical vein persists.…”

“…The umbilical cord usually contains two arteries and one vein. The commonest reported abnormality in the cord is the presence of a single umbilical artery; however, multiple arteries and veins have also been reported [3]. Furthermore, the most commonly reported anomaly of the DV is its agenesis, which is often associated with chromosomal as well as fetal cardiac and extracardiac malformations often manifesting as hydrops fetalis [4,5].…”

Two ductus venosus: a previously unreported anomaly

et al. 2014

In early fetal life, the ductus venosus (DV) connects the umbilical vein, carrying nutrient-rich and oxygenated blood from the placenta to the inferior vena cava (IVC). We present the first ever case of a fetus with two ductus venosus. The fetus presented with a fourvessel cord and a dilated bowel at 31 weeks of gestation. Ultrasonography showed a persistent right umbilical vein. Echocardiographic investigation revealed normal cardiac anatomy with no major malformations. Two DVs with slightly different Doppler patterns were visualized anastomosing with the IVC. The baby was born uneventfully at 39 weeks of gestation with stable hemodynamics. Assuming every supernumerary umbilical vein should be connected to a DV for balanced circulation, a fetus with supernumerary umbilical veins lacking a corresponding number of DV connections is likely to be predisposed to complications such as hydrops fetalis and poor perinatal outcomes. The possibility of one or more umbilical veins lacking a DV connection warrants significant attention and regular monitoring from feto-maternal specialists, given the severity of the associated morbidity and mortality. Keywords Two ductus venosus Á Four-vessel umbilical cordRiassunto Nei primi mesi di vita fetale, il dotto venoso (DV) collega la vena ombelicale, portando il sangue ossigenato, ricco di sostanze nutritive dalla placenta alla vena cava inferiore (IVC). Presentiamo il primo caso in assoluto di un feto con due dotti venosi. Il feto, alla 31 settimane di gestazione, si presentava con quattro vasi nel cordone ombelicale e un intestino dilatato. L'ecografia mostrava la persistenza di una vena ombelicale destra. L'indagine ecocardiografica rilevava un'anatomia cardiaca normale, senza malformazioni maggiori. Sono stati evidenziati due DV con tracciati Doppler leggermente diversi, che si anastomizzavano con l' IVC. Il bambino è nato senza complicazioni a 39 settimane di gestazione, con emodinamica stabile. Supponendo che ogni vena ombelicale soprannumeraria deve essere collegato ad un DV per una circolazione equilibrata, un feto con vene ombelicali soprannumerarie, che manchi di un corrispondente numero di DV rischia di essere predisposti a complicanze come l'idrope fetale e difficoltà perinatali. La possibilità di una o più vene ombelicali prive di DV merita notevole attenzione e un regolare monitoraggio feto-materna, data la gravità della morbilità e la mortalità associate
