Abstract

Background: Obstetrical haemorrhage continues to be an important cause of maternal mortality, accounting for 15-20% of maternal deaths. Placenta previa is an important cause of both antepartum haemorrhage and post partum haemorrhage.

Objectives

1.To observe Incidence of placenta previa among LSCS To analyse risk factors associated with development of placenta previa among study population

Material and Methods: Type of study: Prospective Observational study done among 100 Previous LSCS cases and observed occurrence of placenta previa during 3 months of period.

All the patients with previous history of LSCS, within18-32 weeks of gestation period were included, after observing scar, were further observed for placenta previa.

Results: The incidence of Abnormal Placentation among total deliveries with previous history of Lower Segment caesarean Section during this period in our hospital was 17%. The risk of abnormal placentation is around 4 times higher among the cases of placenta previa cases than normal placentation. This differencence was statistically significant.

Discussion: The incidence of placenta accreta is as high as 67% in patients with placenta praevia and multiple previous CS. This association of previous CS, placenta praevia and placenta accrete is becoming increasingly acknowledged and is causing concern since it carries a significant risk of caesarean hysterectomy with its incumbent morbidity and mortality.

Conclusion: Women with previous LSCS scar are at high risk for developing placenta praevia in subsequent pregnancy. The nature of placenta previa can be unpredictable and harsh on the mother and baby. So, Careful monitoring of high risk pregnancies is of utmost importance.
