ABSTRACT
Objective@#To investigate the sonographic findings of fetal congenital absence of the ductus venosus (ADV) and its effect on the prognosis of fetus.@*Methods@#The ultrasonographic features of 11cases of fetal ADV deficiency diagnosed from December 2013 to June 2017 were retrospectively analyzed, and the fetal prognosis was followed up.@*Results@#Of the 11 cases, umbilical vein flew directly back to the right atrium in 7 cases; umbilical vein connected with the inferior vena cava in 1 case; umbilical vein directly flowed into the iliac vein in 1 case; umbilical vein and portal vein connection in the other 2 cases. Of the 11 cases, 4 cases were solitary and had no abnormality after birth; 5 cases were complicated with abnormal structure of intracardiac and extracardiac system; 2 cases were only followed with abnormal extracardiac system. Of the 5 complicated cases, 1 case was double chorionic twin amniotic membrane pregnancy (the second fetuse had no obvious abnormality) and died after birth; the other 4 cases were terminated before 28 weeks of gestation. Of the 2 complicated cases, 1 case was followed with severe digestive tract abnormalities and died after birth, and the other one was followed with single umbilical artery and hydramnion.@*Conclusions@#Color Doppler ultrasonography is an important means for prenatal screening of fetal ADV.The prognosis of patients with solitary ADV without fetal cardiac dysfunction is good.The prognosis is poor to patients with severe intracardiac and extracardiac abnormality. There is a correlation between the ADV and fetal chromosomal abnormalities. If pregnancy is necessary, fetal chromosome examination should be recommended first and cardiac function should be followed up closely by ultrasound.
