Abstract

Introduction: Placenta previa and placental abruption are one of the most common causes of late pregnancy and delivery bleeding which is associated with increasing of harm and death of mother and fetus. This study was conducted to investigate the outcome and risk factors of placenta previa and placental abruption in pregnant women. Materials and Methods: This descriptive-analytical study was performed on 188 pregnant mothers between 2016-2017. The study population consisted of mothers who referred to the gynecological ward of the hospital with complaints from pain or bleeding in the third trimester of pregnancy and were treated by an obstetrician with the diagnosis of placenta previa and placental abruption. T-test and Pearson correlation were used to investigate the relationship between variables. Results: The results showed that the incidence of placenta previa in pregnant women was 1.3% and the incidence of placental abruption was 1.1%. The most fetal complications of placental abruption were preterm delivery, and maternal complications were bleeding. The most fetal complications of placenta previa were preterm delivery and maternal complications were bleeding before, after and during delivery. The most risk factors of placental abruption were a history of abortion and the most risk factors of placenta previa was the history of previous cesarean. Conclusion: The history of previous cesarean and abortion and stillbirth have had an important role in the occurrence of these complications. Understanding the relevant factors to reduce placenta previa and placental abruption will be effective in reducing complications and thus the health of the mother and fetus.
