The data about the safety of vaginal birth after caesarean section are conflicting. This study in a referral hospital in Sana'a, Yemen investigated the outcome of vaginal birth after caesarean section in 357 women who had one prior caesarean section and were admitted to hospital at term with spontaneous onset of labour. A control group (n = 155) was matched from women without previous caesarean section. The success rate of vaginal birth after caesarean section was 311/357 (87.1%). The mean duration of the first and second stages of labour were not significantly different in the study group (146.2 and 30.7 min respectively) compared with the control group (146.7 and 29.8 min). There were infrequent complications; only 1 woman (0.3%) had ruptured uterus and 3 women (1.0%) suffered uterine dehiscence. There was 1 stillbirth after the uterine rupture but no maternal deaths.
剖宫产术后阴道分娩的安全性数据存在争议。本研究在也门萨那的一家转诊医院进行，共纳入 357 名既往行剖宫产且足月时因自发性临产而住院的妇女，调查其剖宫产术后阴道分娩的结局。选择同期无剖宫产史的妇女 155 名作为对照组。357 名妇女中，311 名（87.1%）成功经阴道分娩。研究组的第一产程和第二产程平均时间与对照组相比均无显著差异（分别为 146.2 分钟和 30.7 分钟）。并发症罕见，仅 1 例（0.3%）发生子宫破裂，3 例（1.0%）发生子宫切口裂开。1 例子宫破裂后发生死胎，但无产妇死亡。
