Abstract
Placenta previa is the condition of pregnancy in which placenta implants in lower uterine segment, partially or completely covering the internal os. This condition may associate with many risk factors. Because with placenta previa pregnancy becomes high risk and fetomaternal morbidities and mortalities are also increased. By knowing the risk factors which are the main causative factors for placenta previa fetomaternal outcome can be optimized The purpose of this study is to find the incidence of placenta previa, and also determine the risk factors for placenta previa. This is descriptive prospective study. This study was done in tertiary care hospital of Pakistan. In this study total deliveries were 5381, total patient with previa were found 325 (6.03%). The risk factors of placenta previa are age more than 35 years (28.92%), smoking (20.16%), multiparity (44%), uterine scar (60.30%), previous evacuation and curettage (24.30%). According to age distribution to mostly patients about 135 out of 325 were found between age group of 36-40 years with percentage of 41.23%. Distribution of patients accrding to gestational age mostly found between age 33-35 weeks with percentage of 54.76 percent amd according to gravidity mostly found between G5–G7 with percentage of 42.46 percent. Aim of the study is to find out the risk factors associated with placenta previa and also determine the incidence of placenta previa in tertiary care hospital of Pakistan.
Highlights
Placenta previa occurs with an incidence of 0.3 - 0.5%
Journal of Gynecology and Obstetrics 2020; 8(3): 67-70. This is observational prospective study to find out the incidence and identifying the risk factors for placenta previa
These risk factors are important in the emergency situation which can aid in careful preoperative preparation and in counseling of women with placenta previa regarding morbidity and mortality
Summary
Placenta previa occurs with an incidence of 0.3 - 0.5%. It is defined by implantation of placenta in lower uterine segment, partially or completely covering the internal os [1]. It is an obstetric complication [2]. Transabdominal and transvaginal ultrasound are complementary diagnostic techniques and should be used as needed. Transvaginal ultrasound is safe for patients with placenta previa and allows a more complete examination of the lower uterine segment [5]. The use of Doppler imagining does not significantly improve the diagnostics sensitivity compared with that achieved by gray scale ultrasonography alone [6]
