ObjectiveTo explore the risk factors influencing the occurrence of cesarean scar pregnancy (CSP), in order to accumulate evidence-based experience for the clinical diagnosis and treatment of these pregnant women. MethodsForty-eight CSP patients were selected as the study group, and 51 cases with cesarean section history but no scar pregnancy throughout re-pregnancy period were selected as the control group. Univariate analysis and logistic regression analysis were performed to ascertain the risk factors for CSP. ResultsUnivariate analysis revealed that there were statistically significant differences between the two groups in the number of abortion , the time from the last cesarean section/abortion time, educational background, the history of pelvic and abdominal surgery, and the vaginal bleeding in early pregnancy (P＜0.05). Multivariate analysis exhibited that the time from the last cesarean section/abortion and vaginal bleeding in early pregnancy were independent risk factors for CSP. ConclusionThe independent risk factors for CSP include the time from the last cesarean section/abortion, vaginal bleeding in early pregnancy. Clinicians should pay attention to them and implement corresponding interventions in the early stage.
