Serial assessments of middle cerebral artery flow velocity with transcranial Doppler sonography in the recovery stage of eclampsia. A case report.
The pathophysiologic changes of eclampsia and/or hypertensive encephalopathy are unclear. Changes of middle cerebral artery flow velocity during the recovery stage in a case of eclampsia are reported. After the disappearance of signs and symptoms, the flow velocity began to increase, owing probably to delayed vasospasm, which was confirmed by magnetic resonance angiography. The vasospasm may be a consequence of eclampsia and may be of small significance in the pathogenesis.
