The hypertensive disorders of pregnancy are a leading cause of maternal mortality and morbidity. According to the group studies of NHPBEB 2000 four entities are defined: Chronic Hypertension (CH) previous to pregnancy, Gestational Hypertension (GH), Preeclampsia/Eclampsia (PE/E) and superimposed Preeclampisa/Eclampsia in Chronic Hypertension (PE/E CH). All this entities have different outcomes and require adequate follow-up and specific attitude.Review all cases of hypertensive disorders in a two-year period, its incidences, and related maternal and fetal complications.In a retrospective study, from January 2008 to December 2009, all files related with hypertensive disorders, seen in our department, were reviewed. The statistic analysis was based on Excel 2007.The global incidence of hypertensive disorders was 3.8% (309 cases), with each entity with an incidence of: 40% in CH, 40% GH, 25% PE/E and 7% PE/E CH. In terms of demographic characteristics the majority of the population were caucasian (46%) and black (40%), the mean age was of 31years (minimum of 12-maximum of 47), and mainly previous Chronic Hypertension and endocrinologic disorders as co-morbidities (Diabetes Mellitus, obesity and thyroid pathology). The fetal/maternal complications were mainly preterm delivery (26.2%), with a low percentage of Abruptio Placentae (1%). Maternal complications were analysed in terms of ICU admissions of 7%, cardiovascular/renal disorders of 1% and maternal bleeding 1%. No maternal death was described. Fetal outcomes were also studied, specifically in terms of birth weight, with an average of 2794 (500-5480g), apgar index in 1st and 5th minute below seven in respectively, 14% and 3.5%.The incidence of maternal complications in our analysis was lower than described in literature. The incidence of preterm delivery was similar to that reported in other studies, mostly due to late pre-terms (>32w).
