Abstract 【Objective】To analyze the clinical features, mother and infant outcomes of scar uterus re-pregnancy complicated with placenta previa, and to explore the intervention measures. 【Methods】 A total of 174 cases with placenta previa treated in our hospital from March 2015 to March 2017 were analyzed retrospectively. According to the existence of maternal uterine scar, the patients were included in the uterine scar group (study group,n=81) and non scar uterus group (control group,n=93). The clinical characteristics and maternal outcome, the impact of uterine scar pregnancy complicated with placenta previa on maternal and neonatal outcomes in each group were analyzed. 【Results】 There was no significant difference between the two groups in the general clinical data such as the age of the pregnant women, the gestational age of admission, the type of placenta previa and the location of placenta previa (P＞0.05). The pregnancy rate of observation group was higher than that of control group, the difference was statistically significant (P＜0.05). The incidence of painless vaginal bleeding and the average amount of vaginal bleeding before operation in two groups were not statistically significant (P＞0.05). Two groups of pregnant women were terminated by caesarean section. The operation time and the amount of postpartum hemorrhage in the observation group were higher than those in the control group. The rate of intraoperative blood transfusion, the rate of intrauterine gauze filling, the rate of placental attachment, the rate of placenta accreta, the rate of suture and the rate of hysterectomy were also higher than those of the control group, the difference was statistically significant (P＜0.05); Premature birth rate of newborn, asphyxia rate and mortality rate of the observation group were slightly higher than that of the control group, but there was no significant difference between the two groups (P＞0.05).【Conclusion】The clinical features of scarred uterus secondary to placenta previa are similar to those of simple placenta previa, but its effect on the outcome of the m aternal is more severe than that of the simple placenta previa. Therefore, attention should be payed to active intervention to ensure the safety of mother and baby.
