The Features of Clinical Imaging, Disease Severity and Pregnancy Outcomes in Posterior Reversible Encephalopathy Syndrome With Preeclampsia or Eclampsia

The purpose of this study is to determine the features of clinical imaging, disease severity and pregnancy outcomes in posterior reversible encephalopathy syndrome with preeclampsia or eclampsia.

The investigators retrospectively collected data (General information, clinical data, biochemical indicators, imaging features, and pregnancy outcome) from pregnant woman diagnosed with PRES with preeclampsia or eclampsia to analyze features of clinical imaging, disease severity and pregnancy outcomes during 2012 to 2021.Then, the investigators grouped all the patients into early onset group and late onset PE group according to gestational weeks to analyze differences of clinical imaging. Finally, the investigators grouped all the patients into good pregnancy outcomes group and poor pregnancy outcomes group according to diagnostic criteria, including the incidence of stillbirth and premature birth, to analyze differences of clinical imaging .

Inclusion Criteria:

1. patients were diagnosed of PRES with PE or E
2. all patients provided written informed consent
