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.
对于胎儿生长受限和AREDV妊娠中胎儿结局的预测及最佳分娩时间，胎儿静脉血流的多普勒记录似乎优于动脉测速和CTG。已有动脉多普勒血流速度改善的相关描述。我们报告了一名患有先天性异常的生长受限胎儿，其静脉导管曾出现舒张末期血流反向，随后舒张末期血流速度暂时恢复正常。这种正常化伴随着CTG改善、脐静脉搏动消失、脐部舒张期血流再现以及脑血流和静脉血流逐渐恢复到“正常”范围。胎儿状况的改善可能是我们观察结果的原因。
