“…With agenesis of DV, abnormal UPSVS develops, here the most important prognostic factor is connection of UV with systemic circulation. Achiron et al [6] and Stabulidau et al [7] studied outcome in fetuses with DV agenesis. When UV directly connects to systemic circulation and bypasses the portal system, this leads to cardiac overload and congestive cardiac failure.…”

To evaluate intraabdominal course of umbilical vein, its relation with portal vein and ductus venosus and its anomalies. All pregnant women were examined during midtrimester anomaly scan between January 2015 and December 2017. With evaluation of umbilical vein in its intraabdominal course, size of umbilical vein, its relation to the stomach and the gallbladder and origin of ductus venosus were studied in middle and upper abdominal axial and sagittal planes by two dimensional and colour doppler sonography. Anastomosis of umbilical vein with portal vein and its further course was examined and detailed anatomical survey was made to look for associated anomalies. Fetal and neonatal outcome was assessed after delivery. Twelve cases of umbilical vein abnormalities were evaluated. Of them, there were three cases of umbilical vein varix, four cases of persistent right umbilical vein and five cases of abnormal umbilical-portal-systemic venous shunt were noted. Examination of the intraabdominal course of umbilical vein and ductus venosus should be a part of second trimester anomaly scan. Proper knowledge of umbilical portal venous system is mandatory.Keywords Ductus venosus (DV) Á Persistent right umbilical vein (PRUV) Á Umbilical vein (UV) Á Umbilicalportal-systemic venous shunt (UPSVS) Á Umbilical vein varix (UVV)

“…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]. Hypothetically each umbilical vein in cords with supernumerary vessels should have a DV to regulate fetal circulation.…”

Two ductus venosus: a previously unreported anomaly

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

Ductus venosus connecting the portal and embryonic venous circulation into the inferior vena cava has a crucial role in fetal circulation. The absence of ductus venosus is a rare anomaly, in which the umbilical vein connection to the venous system may be extrahepatic, bypassing the liver or intrahepatic via the portal venous system. We report three cases of ductus venosus agenesis with associated anomalies. In two of them the connection was directly to the right atrium, whereas the umbilical vein drained to the left internal iliac artery in the third case.
