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.
子痫和/或高血压脑病的病理生理变化尚不清楚。本文报道了1例子痫患者恢复阶段大脑中动脉血流速度的变化。体征和症状消失后，血流速度开始增加，这可能是由于延迟性血管痉挛所致，磁共振血管造影证实了这一点。血管痉挛可能是子痫的结果，在发病机制中可能意义不大。
