Abstract

Placental abruption is a serious complication of pregnancy but its etiology is usually undetermined. Advanced maternal age and multiparity have been associated with an increased risk for placental abruption. Placental abruption may lead to preterm premature rupture of the membranes. The aim of this study was to investigate the leading reasons of placental abruption in pregnant women. Materials & Methods: This retrospective study included 7301 pregnant women and their medical records in Valiasr hospital of Zanjan. The necessary data were collected using a questionnaire. Birth records of 78 cases with placental abruption and 390 randomly selected controls were reviewed retrospectively. Statistical analysis was performed using Pearson's Chi square method. The data were analyzed by SPSS software. Results: Placental abruption was more dominant among mothers over 35 years old (P<0.001). 52.7% of mothers had previous cesarean delivery (p<0.0001) and 29% with a history of abortion in previous pregnancies that is significantly high compared with the control group (p<0.001). 12% of mothers had the history of placental abruption multiparity ( p<0.001) and 16% of infants were preterm (P<0.001). Conclusions: The risk factors for placental abruption found in this study were increased maternal age, multiparity, previous cesarean delivery and history of previous placental abruption. Recognition of these factors is helpful in reducing the occurrence of placental abortion and its risk factors for both the mother and fetus in the future.
