Transcranial Doppler (TCD) has been used in pre\u2010eclampsia\/eclampsia to evaluate non\u2010invasively the cerebrovascular hemodynamics in the maternal middle cerebral artery. TCD has demonstrated in pre\u2010eclamptic women maternal cerebral vasospasm, which does not correlate with mean arterial pressure assessed simultaneously. Estimated cerebral perfusion pressure, assessed using a modified formula, has been shown to be increased in women with severe and non\u2010severe pre\u2010eclampsia. However, in severe pre\u2010eclampsia, elevated cerebral perfusion pressure is counterbalanced by increases in cerebrovascular resistance and cerebral blood flow is unaffected. In eclampsia a significant fall in cerebral vascular resistance occurs which, in the presence of increases in cerebral perfusion pressure, leads to hyperperfusion. Cerebral vascular changes to date have not been sensitive enough to predict the development of pre\u2010eclampsia or eclampsia. Longitudinal studies with the aim of predicting the onset of pre\u2010eclampsia and to assess the effects of various drugs on the maternal cerebral circulation need to be designed.
