Maternal and perinatal outcomes in women with placenta praevia and accreta in teaching hospitals in Western Turkey.

In this retrospective study, we investigated patient characteristics and fetal and maternal outcomes of placenta praevia and accreta at two tertiary hospitals in Istanbul. A total of 364 pregnancies complicated by placenta praevia with (n = 46) and without (n = 318) placenta accreta managed between January 2005 and December 2010 were reviewed. Among 364 women, 46 (12.6%) had placenta accreta and 318 (87.4%) had placenta praevia without accreta. The rates of curettage history and caesarean delivery were significantly higher in the group with placenta accreta. Furthermore, we found that emergency surgery had negative effects on maternal outcomes in the placenta praevia group. In addition, when accreta was suspected at ultrasound examination in women who had placenta praevia, the mean estimated blood loss during surgery was reduced significantly. If placenta praevia is detected, a careful ultrasound examination should be performed and the patient should undergo elective surgery at a tertiary referral hospital.
