[Cerebral lesions in the severe pregnancy induced hypertension: 61 cases of X-ray computed tomography of the brain].

Among 61 patients with severe pregnancy induced hypertension, cerebral lesions were detected on CT scans in 23 cases (37.7%). The positive rates were 5/25 cases in preeclampsia and 18/36 cases in eclampsia. The incidence rate of cerebral lesions in eclampsia was significantly higher than that in preeclampsia (chi 2 test, P < 0.05). Furthermore, it showed that patients with renal impairment and retinal changes were more susceptible to cerebral lesions (P < 0.05), through comparative study of the relationships between either the function of liver and kidney or retinal changes and cerebral lesions. Main manifestations of cerebral lesions were ischemia, edema and infarction. The represented the different pathological stage of cerebral lesions. The cerebral lesions were mainly involved at cortical or subcortical area of bilateral parietal or occipital lobe (60%), secondly at the deep basal ganglia and the superior sagittal sinus. The pathological process of cerebral lesions and the management of pregnancy induced hypertension were analysed.
