Preeclampsia: Diagnosis and management of the atypical presentation

Abstract

Preeclampsia, eclampsia, and HELLP (hemolysis, elevated liver enzymes, low platelets) syndrome remain as major obstetric problems that plague a large percentage of women resulting in an equally large percentage of maternal and perinatal morbidities. It is important that a clinician makes the most accurate diagnosis possible to prevent these adverse maternal and perinatal outcomes. In general, most women will have a classical presentation of preeclampsia (hypertension and proteinuria) at >20 weeks gestation and <48 hours postpartum. However, recent studies have suggested that some women will develop preeclampsia without the classical findings. The purpose of this review is to increase awareness of the non-classical and atypical features of preeclampsia, eclampsia, and HELLP syndrome and their respective management. Atypical cases are those that develop before 20 weeks, beyond 48 hours postpartum and those that present with some of the signs and symptoms of preeclampsia without the usual hypertension or proteinuria. By formulating a rational stepwise approach towards diagnosis, we may prevent the costly consequence of a missed diagnosis and its eventual possible fatalities.
