Effect of amnioinfusion on the umbilical Doppler flow velocity waveform: a case report.
A case of intrauterine growth retardation with marked oligohydramnios is presented in which, following amnioinfusion of 200 ml of a 5% glucose solution, the diagnosis of bilateral renal agenesis was established. Doppler flow study in the umbilical artery revealed a high resistance flow velocity waveform which became normal following amnioinfusion, suggesting cord compression rather than poor uteroplacental perfusion. Abnormal Doppler flow velocity waveforms in the umbilical artery in the presence of severe oligohydramnios should be interpreted with caution.
