Placental Abruption and Analysis of Risk Factors

Objective: It was aimed to evaluate pregnancies with suspected placental abruption and investigate the related risk factors. Methods: Ninety-four pregnancies who delivered by cesarean section for suspected placental abruption in Zeynep Kamil Hospital between 01.03.2012 and 31.01.2013 were included in this study. During the operation, the placenta was examined macroscopically. The presence of retroplacental bleeding or clots in the placenta confirmed the diagnosis of placental abruption. Age, parity, height, weight, blood group, placental localization, previous delivery type, presenting symptoms, pregnancy complications were recorded. Results: The diagnosis of placental abruption was confirmed in 43 (46%) patients while 51 of them (54%) were not confirmed. There was no significant difference between the groups in terms of maternal age, gestational age and body mass index. Mean arterial pressure (MAP) was 95.1±17.8 at the group with placental abruption confirmed and 85.4±8.7 (p=0.006) at the group with placental abruption not confirmed. Placental abruption is more frequent in patients with preeclampsia (OR=8.5; p=0.022). When the groups were compared according to their blood groups; 87.5% of pregnant women with 0 Rh (+) blood group was confirmed for diagnosis of placental abruption (OR=8.7; P=0.005). Conclusion: Identification of risk factors for placental abruption is the basic criterion for the management and reduction of potential complications.
