Objective: To study the incidence of placenta previa. To examine the risk factors and fetomaternal outcomes in placenta previa in previously scarred and unscarred uterus in Dept. of Obstetrics & Gynecology, S.P. Medical College, Bikaner. Methodology: The patients who came with complaint of painless bleeding per vagina after 28 weeks of gestation were hospitalized and were divided into two groups, Group A in which placenta previa occurred in a previously scarred uterus and Group B in which placenta previa occurred in an unscarred uterus. Results: The overall incidence of the placenta previa was 0.56 %. Incidence of placenta previa in group A (Scarred uterus) was 1.15% which was higher than group B (Unscarred uterus) i.e. 0.35%. Cesarean section with Uterine artery ligation and uterine packing was present in 12.9% cases and 3.70% cases respectively in group A while in 2.08 % cases each in group B. Previous 1 LSCS and previous 2 LSCS was present as a risk factor in group A only in 88.89% cases & 11.11% cases respectively. Conclusion: An increase in incidence of prior cesarean section and advanced maternal age probably contributes to a rise in number of pregnancies complicated with placenta praevia and its association with adverse maternal & perinatal outcome. Early diagnosis by ultrasound and planned delivery should be the mainstay of management.
