This descriptive study was conducted to evaluate the risk of uterine rupture in cases of late vaginal induced abortions among women with previous cesarean sections. 23 women were referred at a mean gestational age of 23.9 (SD 6.9) weeks of gestation after one or two cesarean sections. Indications for terminating the pregnancy were maternal diseases in 4 cases and fetal anomalies in 19 cases. RU 486 and/or prostaglandins were used for cervical ripening and to induce labor. Vaginal birth was obtained in 20 cases (86.9%) with an average duration of 72 (SD 52) h. Cesarean section was performed in the remaining 3 women because no cervical dilation could be obtained. One uterine rupture occurred and was treated with conservation of the uterus. Late termination of pregnancy in such cases can be achieved without cesarean section with a high success rate.
本描述性研究旨在评估既往有剖宫产史的妇女晚期阴道引产时子宫破裂的风险。23例妇女在一或两次剖宫产术后，平均妊娠23.9（标准差6.9）周时前来就诊。终止妊娠的指征为4例母体疾病和19例胎儿畸形。使用RU 486和/或前列腺素进行宫颈成熟和引产。20例（86.9%）经阴道分娩，平均产程72（标准差52）小时。其余3名妇女因宫颈未扩张而行剖宫产。发生1例子宫破裂，行子宫保留治疗。此类病例晚期终止妊娠可不经剖宫产而获得较高成功率。
