Background: to assess whether certain risk factors predispose pregnancies complicated by PPROM (preterm premature rupture of membrane) to placental abruption.

Methods: A prospective study was done during July-Nov 2016 in Khalij Fars general hospital on singleton pregnancies between 20-36 weeks gestation with verified PPROM. Data were collected through patients' demographic data and their hospital documents. The diagnosis of abruption was verified by gross placental examination. All risk factors were compared in both groups of pprom with and without abruption.

Results: The incidence of abruption placenta in pprom patients was 8 %( n=24). A significant correlation and increased incidence of placental abruption was seen in patients with intrapartum fetal distress (P<0.05), APGAR <6 (P<0.05), Urinary tract infection (P> 0.05), parity (P<0.001), previous abruption (P<0.05), chorioamnionitis (P<0.05) and oligohydramnious (P<0.05).

Conclusion: abraptio placentae in preterm premature rupture of membrane cases has a strong correlation with chorioamnionitis, oligohydramnious and previous abruption. With identification of these predisposing factors, threatening ingredient can be prevented in order to decrease both maternal and fetal mortality.
