Objective: To evaluate perinatal and obstetric outcomes of preeclampsia-eclampsia cases and to define prognostic factors on abnormal outcome. To make a comment on preeclampsia classification according to our clinical findings. Material and Methods: A retrospective investigation of 311 cases of preeclampsia-eclampsia delivered in our clinic, 2001 January-2009 December inclusive. Perinatal and obstetric outcomes are evaluated. Results: Delivery before 34 weeks, fetal growth restriction, HELLP syndrome and abruptio placenta was diagnosed in 55.9%, 54%, 3.9% and 3.2% of cases retrospectively. Fetal and neonatal mortality rates were 10% and 21.8% respectively. There was no maternal mortality and maternal morbidity rate was 18.6%. Fetal growth restriction, fetal mortality and maternal morbidity rates were significantly higher in severe preeclampsia-eclampsia than mild preeclampsia (p< 0.01). Fetal growth restriction, fetal and neonatal mortality and maternal morbidity rates were significantly higher in cases delivered before 34 gestational weeks (p< 0.01). Fetal growth restriction, fetal and neonatal mortality rates in mild preeclamptic cases delivered before 32 gestational weeks were 47.5%, 10% and 37.5% respectively. Fetal growth restriction, fetal and neonatal mortality rates were significantly higher in mild and severe preeclampsia cases delivered before 32 gestational weeks than above 36 gestational weeks (p< 0.01). Conclusion: Preeclampsia owns risks for both the mother and the fetus. Preeclampsia that develops early in pregnancy is mostly due to placentation abnormality and is potentially more dangerous.
