ABSTRACT
To evaluate relationship of maternal hepatic vein Doppler flow parameters and cardiac output (CO) with neonatal birth weight in uncomplicated pregnancies (UP) and pregnancies complicated by fetal growth restriction (FGR) .


Methods:

Hepatic vein impedance index (HVI), venous pulse transit time (VPTT), and CO were measured in women with UP at the 14th-37th weeks and complicated by FGR at the 26th-37th weeks who underwent maternal hepatic hemodynamic and echocardiographic examination during the ultrasonography. After delivery, the birth weight and the birth weight percentile of each neonate in this study were recorded. Correlations among HVI, VPTT, and CO were analyzed.


Results:

In the UP group, HVI, VPTT, and CO changed with the increase of gestation. In the FGR group, HVI was higher, VPTT was shorter, CO and neonatal birth weight were obviously lower than those in the UP at the 26th-37th weeks (P<0.05).


Conclusion:

There is a series of adaptive changes in hepatic venous hemodynamics and CO in UP with the increase of gestation to meet the demand of fetal growth, while the maladaptive changes in hepatic venous hemodynamics and CO in pregnant woman may contribute to FGR.
