The aim of this study was to determine whether a short interpregnancy interval is associated with uterine scar failure in laboring patients with previous low transverse cesarean delivery.
This was a case-control study of uterine scar failures among laboring patients with previous low transverse cesarean delivery. Control patients underwent abdominal delivery during labor after failure of an attempted vaginal birth after cesarean delivery in the same month as case patients.
An interpregnancy interval of <6 months was significantly more prevalent among case patients with uterine scar failure (P =.02). Mean interpregnancy interval was less in all cases of uterine scar failure (P = .06).
Interpregnancy interval was inversely associated with likelihood of uterine scar failure during subsequent labor.
本研究旨在确定妊娠间隔时间短是否与既往有低位横切口剖宫产史的产妇分娩时子宫瘢痕破裂相关。
这是一项针对既往有低位横切口剖宫产史的产妇子宫瘢痕破裂的病例对照研究。对照患者在与病例患者同月剖宫产术后试产失败后，于分娩期间行剖宫产。
子宫瘢痕破裂的病例患者中，妊娠间隔时间<6个月的情况明显更为普遍（P = 0.02）。所有子宫瘢痕破裂病例的平均妊娠间隔时间均较短（P = 0.06）。
妊娠间隔时间与后续分娩时子宫瘢痕破裂的可能性呈负相关。
