Cerebral Hemodynamics in Preeclampsia and Eclampsia

Abstract

Significantly higher MCA velocities in eclamptic, but not preeclamptic, women compared with those in normotensive pregnant women suggests that moderate to severe vasospasm is associated with eclampsia.

Serial Assessment in Eclampsia of Cerebrohemodynamics by Combined Transcranial Doppler and Magnetic Resonance Angiography

“…Lack of significant vasospasms 5 h after an eclamptic seizure seems inconsistent with reports of segmental vasospasms by Qureshi et al [2] and by Raps et al [4]. However, their angiographic examinations were done more than 36 h after seizure attacks, in contrast to 5 h in our case.…”

Eclampsia: A neurological perspective

“…Headache character (throbbing or pounding) and other associated symptoms described by most of these women (blurring of vision, photophobia, sonophobia, nausea, vomiting) are similar to the headaches described in patients with migraine without aura [11]. This is an interesting observation, as eclampsia is considered to be a multisystem vascular syndrome by many and vascular changes as evidenced by four vessel cerebral angiogram, magnetic resonance angiogram (MRA) and transcranial Doppler (TCD) studies provide evidence for the same [12][13][14][15][16][17][18].…”

Maternal transcranial Doppler in pre‐eclampsia and eclampsia

“…Qureshi et al 42 reached similar conclusions about MCBFV in eclamptic patients. His three eclamptic patients had significantly higher mean flow velocities and lower average pulsatility indices than did normotensive patients (average MCA‐mean flow velocity, 165 vs. 79 cm/s; P = 0.007).…”
