“…High‐resolution sonography combined with 3D/four‐dimensional applications has advanced our ability to visualize the normal fetal portal venous system and its abnormalities 6,7 . As a result, in utero detection of CPSS is feasible but still limited.…”

“…The routine fetal ultrasound scan was performed in accordance with the practice guidelines of the International Society of Ultrasound in Obstetrics and Gynecology, 4 using a Voluson E8 Expert machine (GE Healthcare, Kretzchnik). Findings such as an abnormal tubular structure, a prominent hepatic vein and congestive heart failure can be important clues for identifying CPSS, 5 which would promote the fetal umbilical‐portal‐systemic venous survey 6,7 …”

Aim: To review our experience with the prenatal diagnosis of congenital portosystemic shunt (CPSS). Methods: This is a retrospective study of CPSS cases examined at an ultrasonographic tertiary referral center from 2013 to 2019. The anatomical origin and drainage of the shunt were assessed. Feto-maternal clinical characteristics and long-term outcomes were investigated via medical files and telephone interviews with the mothers. Results: Eleven cases were reviewed. Based on the anatomical origins, before or after portal vein division, cases were classified into extrahepatic portosystemic shunt (EHPSS, n = 3, 27.3%) and intrahepatic portosystemic shunt (IHPSS, n = 8, 72.7%). Additional abnormalities were also observed in the EHPSS (n = 2, 66.7%) and IHPSS (n = 3, 37.5%) groups. Intrauterine growth restriction was the most common abnormality (n = 4, 80%). The median age of the pregnant women was 31.9 years (range 26~43 years). Most cases (n = 8, 72.7%) were diagnosed in the third trimester, and the median gestational age was 31 +5 weeks (range 24~36 +6 weeks). Three cases underwent karyotype examinations, and one had trisomy 13. The median time after birth was 2 years (range 0.7~5.7 years). The overall postnatal live-birth rate was 60% (6/10), not including one case with no data on pregnancy outcome. The mothers of the six live births indicated that their children were in excellent health. Conclusion: This study indicates that prenatal CPSS diagnosis is feasible, especially in the third trimester. IHPSS is more common than EHPSS. Complicated cases most often occur with EHPSS. Intrauterine growth restriction is the most common concomitant abnormality. The prognosis of most cases is good.

“…Between the 4th and the 6th week of gestation, the subhepatic intervitelline anastomosis transforms into a large, definitive intrahepatic channel connecting the intrahepatic portal vein and the umbilical vein, and known as the sinus intermedius or portal sinus (Mavrides et al,2001; Paris et al,2004). This transformation results from the regression of the left half of the subhepatic anastomosis, which is likely incorporated into the umbilical vein, as suggested by the apparent displacement of the ramus angularis from the left angle of the subhepatic anastomosis to a point located caudally along the umbilical vein (Dickson,1957).…”

The vascular architecture of the human liver is established at the end of a complex embryological history. The hepatic primordium emerges at the 4th week and is in contact with two major venous systems of the fetal circulation: the vitelline veins and the umbilical veins. The fetal architecture of the afferent venous circulation of the liver is acquired between the 4th and the 6th week. At the end of this process, the portal vein is formed from several distinct segments of the vitelline veins; the portal sinus, deriving from the subhepatic intervitelline anastomosis, connects the umbilical vein, which is the predominant vessel of the fetal liver, to the portal system; the ductus venosus connects the portal sinus to the vena cava inferior. At birth, the umbilical vein and the ductus venosus collapse; the portal vein becomes the only afferent vein of the liver. The efferent venous vessels of the liver derive from the vitelline veins and are formed between the 4th and the 6th week. The hepatic artery forms at the 8th week; intrahepatic arterial branches progressively extend from the central to the peripheral areas of the liver between the 10th and the 15th week. Hepatic sinusoids appear very early, as soon as hepatic cords invade the septum transversum at the 4th week. They then progressively acquire their distinctive structural and functional characters, through a multistage process. Vascular development and differentiation during liver organogenesis is, therefore, a unique process; many of the cellular and molecular mechanisms involved remain poorly understood.

“…Sonographic evaluation of the fetal UPVS was described in the early 1980s2, 3. However, in recent years, meticulous pathological studies4, 5 and high‐resolution sonography combined with three‐dimensional (3D)‐4D applications have advanced our knowledge and ability to identify the normal UPVS and its abnormalities6–9.…”
