Abstract

Background: The association of posterior reversible encephalopathy syndrome (PRES) and severe preeclampsia/eclampsia has been established but the frequency is uncertain.

Objectives: To determine the frequency of PRES in severe preeclampsia or eclampsia.

Methods: We searched published articles in PubMed, Cochrane library, Embase, and CINAHL from 1990 to 2020. We included articles that reported on six or more cases of PRES with eclampsia or severe preeclampsia who underwent neuroimaging during pregnancy or up to 6 weeks postpartum.

Results: We identified 29 studies presenting data on 1519 women with eclampsia or severe preeclampsia. Among 342 women with eclampsia who had neuroimaging, 176 (51.4%) were diagnosed with PRES. Of 121 women with severe preeclampsia, 24 (19.8%) had PRES. The pooled maternal death rate was 5.3% (21/395).

Conclusion: PRES is commonly reported on neuroimaging of women with eclampsia/ severe preeclampsia. The role of neuroimaging in eclampsia and especially in women with severe preeclampsia requires re-evaluation as further management is often dictated by this finding.

重度子痫前期和子痫孕妇后部可逆性脑病综合征的系统评价

后部可逆性脑病综合征（PRES）与严重子痫前期/子痫的相关性已经确定，但其频率尚不确定。确定重度子痫前期或子痫患者的PRES频率。我们检索了1990年至2020年在PubMed、Cochrane图书馆、Embase和CINAHL发表的文章。我们纳入了报道6例或6例以上妊娠期或产后6周接受神经影像学检查的先兆子痫或重度先兆子痫患者的文章。我们确定了29项研究，这些研究提供了1519名患有子痫或严重子痫前期的女性的数据。在342名接受神经影像学检查的子痫妇女中，176名（51.4%）被诊断为PRES。在121名严重子痫前期妇女中，24名（19.8%）患有PRES。合并的孕产妇死亡率为5.3%（21/395）。PRES常见于子痫/重度子痫前期妇女的神经影像学。神经影像学在子痫中的作用，尤其是在患有严重子痫前期的女性中的作用需要重新评估，因为这一发现往往决定了进一步的治疗。
