Placenta previa is the pathology of placenta in which the placenta lies completely or partially within the lower uterine segment. According to its relationship with internal os it is divided into four grades 1, 2, 3, 4. The objective of this study was to explore the risk factors and pregnancy outcome of patient with placenta. A case control study was done on 382 subjects in which 82 were included in the cases, and 300 were included in controls who presented at Obstetrics and Gynecology Department of Tripoli medical center during 2011. Diagnosed patients of placenta previa were included in case group and other healthy subjects were included in the control group and statistical significance was also calculated. In conclusion, previous history of cesarean section, previous history of D + C, previous history of placenta previa is independent risk factors for placenta previa. An increase in the incidence of these risk factors probably contributes to a rise in the number of pregnancies complicated with placenta previa and its association with adverse maternal and prenatal outcome. Carful surveillance of these risk factors is recommended with timely delivery in order to reduce the associated complication.
