Abstract:
Objective To evaluate prenatal sonograpic findings and clinical value in fetus with congenital portal-hepatic venous shunt.Methods The prenatal ultrasonographic characteristic of ten cases of congenital portal-hepatic venous shunt were analyzed and summarized.Results Three cases had portal vein-left hepatic venous shunt,two cases with portal vein-right hepatic venous shunt,two cases with situs inversus of left right portal vein,and three cases with multiple shunt among portal and hepatic veins.All the 10 cases with portal-hepatic venous shunt had common sonographic features,①Two-dimensional ultrasound revealed the distal hepatic veins.The hepatic vein and portal vein were both visualized on the same plane and connected by an anechoic area.②Vascular signal were noted inside the anechoic area.③Blood flow inside the anechoic area demonstrated by spectral Doppler was similar to that of the portal vein.Conclusions Prental ultrasonography is valuable in the diagnosis of fetal portal-hepatic venous shunt.
