Placenta Previa a Lethal Disease: A Correlation With Uterine Scaring

Abstract

Placenta previa is the main cause of fetomaternal morbidity and mortality globally. Multiparity, advanced maternal age, infertility treatments and recurrent abortions has been linked to the prognosis of placenta previa. Scarred uterus due to history of Cesarean sections is main risk factor as frequently, primary cesarean sections result in recurrent cesareans, which can cause placenta previa. Our study aims to evaluate sonographic association of placenta previa in scarred and unscarred uterus. It was a descriptive cross-sectional study including 84 patients of placenta previa. Data of their previous pregnancies and previous Cesarean sections are also collected. The data is collected from the radiology department of Bhatti International Teaching Hospital Kasur within 3 months. Convenient sampling technique is used in data collection. Among the total 84 cases of females with placenta previa, most of the females had age below 30 years. Previous Cesarean section was mainly associated with the prevalence and grades of placenta previa, while number of previous pregnancies has a non-significant relation to the grades of placenta previa in scarred group of females. Therefore, our study showed that scarring has significant affect on the ultrasonographic grades of placenta previa rather than an unscarred uterus. Our findings indicate that placenta previa grading is significantly greater in the scarred group, indicating a more serious condition than the unscarred group. The result emphasizes the significance of uterine scarring in the development of placenta previa by demonstrating the strong correlation between the severity of the condition and previous Cesarean sections.
