“…If the DV is defined as a connection of the hepatic/UV/portal complex to the prediaphragmatic infundibulum, separate from the IVC and hepatic veins, then there is no such thing as DVSS. Simcha Yagel, who authored or co‐authored a major part of the previous publications of this group, just recently looked at it in another way: USS and DVSS were classified as DV agenesis and subdivided into types with broad or narrow connection to the systemic veins. He hypothesized that only the narrow type of connection enables normal development of the portal circulation, as is confirmed in the cohort in this manuscript.…”

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)

“…Agenesis of the DV or abnormal development of the portal system, for example, may have grave prognoses. In fact, it would appear that some malformations of the venous system are not as rare as believed previously, and that more would be diagnosed prenatally if practitioners were cognizant of their sonographic appearance and associated anomalies. Diagnosis of anomalies of the cardinal, vitelline or umbilical venous systems should prompt thorough investigation of the other segments of the cardiovascular system.…”

“…Characteristic Doppler waveforms of fetal precordial veins investigated most commonly: (a) umbilical vein; (b) splenic artery and vein (note that, as splenic artery and vein are always imaged together, their waves appear together); (c) ductus venosus; (d) left hepatic vein; (e) inferior vena cava.

The fetal precordial veins comprise a complex system of vessels delivering oxygenated blood from the placenta through the umbilical vein to the developing fetus. This system draws most of its nomenclature from the adult venous system. However, the direction of flow, as well as the relative size and prominence of the component vessels, differ from those in the postnatal circulation. Understanding the unique characteristics of the fetal circulation and its differences from the postnatal system can aid the sonographer in identifying normal and anomalous anatomy (Figure 1).
