Transcranial assessment of maternal cerebral blood flow velocity in patients with pre‐eclampsia

Abstract

In pre-eclamptic patients, we found increased MCA mean velocity before the onset of visual disturbance. Transcranial Doppler may be useful for the evaluation of cerebral hemodynamics and the prediction of eclampsia.

A low dose (‘Dhaka’) magnesium sulphate regime for eclampsia

“…The mechanism of action of magnesium sulphate is uncertain, but there is evidence from computed tomography and magnetic resonance angiographic studies implicating cerebral vasospasm and ischemia in the genesis of eclampsia (12–14). Magnesium seems to reverse and ameliorate the effects of cerebral ischemia (15).…”

A low dose ('Dhaka') magnesium sulphate regime for eclampsia: Clinical findings and serum magnesium levels

“…The mechanism of action of magnesium sulphate is uncertain, but there is evidence from computed tomography and magnetic resonance angiographic studies implicating cerebral vasospasm and ischemia in the genesis of eclampsia (12)(13)(14). Magnesium seems to reverse and ameliorate the effects of cerebral ischemia (15).…”

Maternal cerebral hemodynamics in pregnancy‐related hypertension. A prospective transcranial Doppler study

“…The fact that raised V mean values were found symmetrically in both hemispheres, in all basal arteries, over the whole insonated length of the arteries and also in the ICA in the three eclamptic patients suggests vasodilatation as the underlying mechanism. Ohno and coworkers 86 found an increase in V mean ICA of 11% in 18 pre-eclamptic women, accompanied by an increase in V mean MCA of 67%. This finding is in keeping with our results, i.e.…”
