目的探讨瘢痕子宫产妇再次妊娠经阴道分娩的安全性及可行性。方法回顾性分析瘢痕子宫再次妊娠经阴道分娩的132例产妇(瘢痕子宫组)的临床资料,另选择同期分娩的无子宫手术史的产妇140例作为对照组,观察两组产妇经阴道分娩的成功率、侧切率、产后出血率、新生儿评分及产程时长情况。结果瘢痕子宫组侧切率高于对照组(P<0.01),两组产妇在阴道分娩成功率、产后出血率、新生儿评分及产程时长无统计学差异(P>0.05)。结论瘢痕子宫再次妊娠经阴道分娩具有较高的成功率和安全性,符合阴道分娩指征的产妇应给予阴道分娩机会。 Objective To investigate the safety and feasibility of transvaginal delivery of pregnant women with scar uterine pregnancy. Methods The clinical data of 132 maternal (scar tissue) women who had vaginal delivery of scar pregnancy were retrospectively analyzed. Another 140 maternal women without history of uterine surgery were selected as the control group. The successful delivery of vaginal delivery Rate, lateral incision rate, postpartum hemorrhage rate, neonatal score and duration of labor. Results The rate of unilateral cesarean section was significantly higher than that of the control group (P <0.01). There was no significant difference in the success rate of vaginal delivery, postpartum hemorrhage, neonatal score and labor duration between the two groups (P> 0.05). Conclusions Transvaginal delivery of scar pregnancy after uterine pregnancy has a higher success rate and safety. The women who meet the indications of vaginal delivery should be given vaginal delivery.
