title: Characterization of Atypical Preeclampsia.
abstract: OBJECTIVE
  To characterize patients with atypical preeclampsia (PE), in relation to socio-demographic characteristics, clinical presentation, maternal complications and perinatal outcome.
  
  
  METHODS
  Between July 1, 2011 and November 30, 2013, a cohort was created of women attended at a Obstetric High-dependency Unit who met criteria for atypical PE: gestational hypertension with severe hypertension or symptoms or laboratory signs suggestive of microangiopathy/hemolysis; normotensive proteinuria with the presence of symptoms or laboratory signs suggestive of microangiopathy/hemolysis; presence of PE or eclampsia or HELLP syndrome appearing after 48 h postpartum, and, PE or eclampsia appearing before 20 weeks of pregnancy.
  
  
  RESULTS
  A total of 200 women fulfilling criteria for atypical PE, were included: 61.5% corresponded to non-proteinuric gestational hypertension, 35.5% to normotensive proteinuria and 3% to PE/eclampsia in late postpartum. Criteria for severe maternal morbidity were present in 12% of the cases and there were no maternal deaths. There were 6 perinatal deaths.
  
  
  CONCLUSIONS
  Atypical preeclampsia is a type of preeclampsia not fully recognized that is associated with maternal and neonatal morbidity, mainly related to smallness-for-gestational-age and low birth weight. Vasospasm symptoms are a key element to detect this condition.
