Frequency of placenta previa in previously scarred and non scarred uterus

ABSTRACT

To determine the frequency of placenta Previa in patients coming to a tertiary care unit with previously scarred and non-scarred uterus. A descriptive cross sectional study was carried on 114 cases who underwent caesarean sections [37 cases out of 645 cases with non scarred uterus and 77 cases from 721 cases with scarred uterus] in the department of obstetrics and gynecology Lady Willingdon Hospital from January 2008- December 2011. Most patients [47.36%] were between 26-30 years age group, presented with gestational age between 36-40 weeks [70.17%], were mostly G2-4, while frequency of placenta Previa in non-scarred uterus was 32.45% [37 cases], and frequency in previously scarred uterus was 67.54% [77 cases]. Major degree Previa was found in 88 cases [77.19%]. There were 5.70% cases of placenta Previa from non-scarred uteruses and 10.67% cases of placenta Previa [10.67%] from already scarred uteruses. Stratification revealed a higher trend of the morbidity with the increase in number of previous caesarean sections. A significantly higher frequency of placenta Previa was found among patients coming to a tertiary care hospital with previously scarred uterus
