妊娠子痫并发脑血管病的CT诊断

CT evaluation of cerebrovascular diseases in Pregnancy with eclampsia

目的：妊娠子痫并脑血管病并非少见，且脑水肿与脑梗塞的早期ＣＴ表现极为相似，早期诊断、及时治疗至关重要，本文旨在分析各并发症的ＣＴ特点，重点讨论脑水肿与早期脑梗塞的鉴别诊断。材料与方法：妊娠子痫合并脑血管病共２４例，其中脑水肿１２例，脑梗塞７例，脑内血肿４例，所有病人发病后急诊作ＣＴ平扫，３例行增强扫描，１５例病人复查ＣＴ。结果：脑水肿ＣＴ表现为双侧顶、额、枕叶较为对称的片状低密度区，以顶叶为甚，脑梗塞ＣＴ表现类似脑水肿，脑内血肿ＣＴ表现均为皮层下血肿。结论：ＣＴ检查妊娠子痫并脑血管病具有迅速、准确的诊断价值。

Purpose:The cerebrovascular diseases in pregnancy with eclampsia are not rarely seenmoreover CT finding of cerebral edema and early cerebral infarction were very similar and the early diagnosisand timely treatment were very important.This article analysed the CT features of each complicalion and emphaticaly discussed the diffirential diagnosis between cerebral edema and early infarction.Materials and Methods s: Ofthe 23 cases reviewed included:12 cases of cerebral edema,7 cases of cerebral infarction and 4 cases of intrac-erebral hematoma. Emergent plain CT scan were performed in all the cases,3 cases recived enhancement CTscan, 15 cases had follow-up CT scan. Results: The CT finding of cerebral edema demonstrated symmetric lowdensity area in parietal, occipital or frontal lobe, CT finding of early cerebral infarction was similar to cerebraledema, all the intracerebral hematoma located in subcortex.Conclusion: CT examination of cerebrovascular acci-dent in pregnany with eclampsia had rapid and accurate diagnostic value.[
