The Relation Of Placenta Previa With History Of Previous Cesarean Section And Miscarriages

Abstract

Background and objectives: The factors that increase the risk of placenta previa in subsequent pregnancies include past miscarriages and the scar from a previous cesarean operation. This study aimed to determine whether a history of cesarean section or miscarriage was related to placenta previa at Sulaimani Maternity Teaching Hospital. Methods: At the Sulaimani Maternity Teaching Hospital, this case-control study was conducted between the 11th of September 2021 to the 31st of June.2022. A total of 100 women provided information, which was divided into two groups: Group A, which included 50 pregnant women with gestational ages between 30 and 40 weeks and confirmed placenta previa, and Group B, which included 50 pregnant women randomly selected with pregnancy lengths of 30 to 40 weeks and the placenta was in its usual location. Detailed history was taken from each woman, through this the relationship of placenta previa with previous cesarean section and miscarriages was studied. Results: The results of this study revealed that prior cesarean sections were previously performed in 74% of cases of placenta previa, compared to 46% of controls (p value = 0.004). In addition; there was no correlation between placenta previa and prior miscarriages (p value= 1.000), and a highly significant correlation was seen between the rise in previous cesarean deliveries and the presence of accreta (p value = 0.003). Conclusion: The likelihood of placenta previa in subsequent pregnancies is dramatically increased in this study by past cesarean deliveries; previous miscarriages have no significant impact on placenta previa development.
