Ominous normalization of middle cerebral artery flow velocity waveforms preceding fetal death: case report.
The loss of middle cerebral artery compensatory vasodilation appears to be ominous in fetuses with absent end-diastolic umbilical waveforms. The authors report a case with a loss of the 'brain-sparing effect' 24 h before fetal death. Current pathophysiological explanations are discussed.
