Normalisation of a severely abnormal ductus venosus Doppler flow velocity waveform in a growth-retarded fetus with absent end-diastolic flow in the umbilical artery and congenital anomalies.
Doppler recordings of fetal venous blood flow seem to be superior to arterial velocimetry and CTG concerning the prediction of fetal outcome and optimal time of delivery in pregnancies with fetal growth retardation and AREDV. An improvement of arterial Doppler flow velocities has been described. We report the reappearance of a normal end-diastolic flow velocity in a ductus venosus temporarily showing reversed end-diastolic flow in a growth-retarded fetus with congenital anomalies. This normalization was accompanied by an improvement of the CTG, a loss of umbilical vein pulsations, a reappearance of umbilical diastolic flow and a progressive return of cerebral and venous blood flow into the 'normal' range. Improvement of fetal condition may be the explanation for our observation.
