Abstract:【Abstract】 Objective To study the clinical outcomes of different delivery modes for secondary pregnancy of women with cicatricial uterus, and provide the basis for the reasonable choice of delivery mode. Methods 113 cases of clinical data of cesarean section in pregnant women with different delivery modes in our hospital form October 2014 to December 2016 were divided into vaginal delivery group (group A, 48 cases), vaginal delivery failure after cesarean section group (group B, 19 cases) and cesarean section group (C group, 46 cases), the other selected non uterine scar pregnancy vaginal delivery group (group D, 51 cases). The child birth bleeding, hospitalization time, the incidence of puerperal fever, and neonatal Apgar score were observed. Results The results of uterine scar pregnancy vaginal delivery success rate was 466% (48/113). The higher the degree of cervical receptivity at admission (cervical length) and anterior uterine wall muscle layer thickness value, the higher the success rate of vaginal delivery was. There was no significant difference between group A and D in the amount of blood loss during labor or during operation and the average hospital stay. Compared with group A, blood loss and average hospital stay in group B and C were significantly increased (P<0.01). Compared with A group, B group, C group and D group had no significant difference (P>0.05) in the incidence of puerperal fever, neonatal general situation and Apgar score. Conclusion On the premise of strict monitoring of clinical risk, to some extent, vaginal delivery of scar uterus is better than cesarean section in vaginal bleeding and hospitalization days.
