Feto-Maternal Outcome In Placenta Previa In Scarred Versus Non-Scarred Uterus

ABSTRACT

Introduction: Placenta previa complicates 0.3–0.5% of all pregnancies and is a major cause of third-trimester hemorrhage. Itaffects both mother and fetus; therefore, it is important to study this condition and its complications.Aims and Objectives: The aims and objectives of this study were to compare the incidence of placenta previa, associated factors,complications, placental position, mode of delivery, and fetal and maternal outcome in non-scarred uterus and scarred uterus.Materials and Methods: A total of 100 patients identified with the diagnosis of placenta previa beyond 28 weeks of gestationwere taken. The cases were divided into two groups Scarred and unscarred. Both the groups were compared for parameterssuch as maternal age, parity, frequency of placenta previa, fetal outcome, operative procedures, and maternal morbidity andmortality.Results: Of 100 patients, 23% were in the age group between 18 and 25, 49% between 26 and 30, and 28% between 31 and40 years. 6% of patients in scarred uterus had 2 or more previous dilatation and curettage. In all patients of scarred uterus, 80%of the patients had previous 1 cesarean section, while 15% had two previous sections and 4.5% had previous three cesareansections. Chances of placenta previa increase both with dilatation and curettage and previous cesarean sections. However, itwas found in this study that fetal outcome did not differ much with the presence of scarred uterus.Conclusion: It can be concluded that, in our study, the cesarean section had a significant relationship with placenta previa andthis risk becomes very high with escalation in number of cesarean sections.
