ObjectivesThe purpose of our study was to examine the hypothesis that pregnancies complicated with placenta previa have an increased risk of placental insufficiency associated pregnancy complications (IUGR, preeclampsia, placental abruption and perinatal mortality).Materials And MethodsOur study included all deliveries that occurred at Soroka University Medical Center (Beer Sheva, Israel) between January 1998 and December 2013. Of them 1,249 were complicated by placenta previa and represented our study group. A composite outcome was created to include conditions associated with placental insufficiency. It included hypertensive disorders (i.e. gestational hypertension, mild and severe preeclampsia, HELLP and eclampsia), small for gestational age neonates and placental abruption.ResultsPatients with pregnancy complicated by placenta previa had significantly different obstetrical characteristics including bad obstetric history (8% vs. 4%, p < 0.001), recurrent abortions (11% vs. 5%, p < 0.001). Patients with placenta previa had higher rates of vaginal bleeding in the second half of pregnancy (3% vs. 0%, p < 0.001), gestational diabetes (8% vs. 5.5%, p < 0.001), placental abruption (10% vs. 1%, p < 0.001), adherent placenta (4% vs. 0.5%, p < 0.001), preterm delivery (52% vs. 8%, p < 0.001), with a median gestational age of 36 vs. 39 weeks, p < 0.001. The composite outcome was significantly more prevalent in the placenta previa group (21% vs. 13%, p < 0,001).ConclusionsOur study demonstrated an increased rate of placental insufficiency associated complications in women with placenta previa. This is of clinical relevance and suggests that a careful surveillance for women with placenta previa may help in minimizing maternal, fetal and neonatal complications.Copyright © 2017.
