背景：机械性改变宫颈角度已被提出来减少自发性早产。通过超声测量子宫颈角预测自发性早产的性能知之甚少。目的：我们试图确定一种新的超声标记物，子宫颈角，是否与一般人群中自发性早产的风险相关。研究设计：我们从2014年5月到2015年5月进行了一项回顾性队列研究，对16 0/7- 23 6/7周之间的单胎妊娠进行了经阴道超声宫颈长度筛查。再次测量子宫下段与宫颈管之间的子宫颈角。主要结果是预测自发性早产
BACKGROUND: Mechanical alteration of the cervical angle has been proposed to reduce spontaneous preterm birth. Performance of the uterocervical angle as measured by ultrasound for predicting spontaneous preterm birth is poorly understood.OBJECTIVE: We sought to determine whether a novel ultrasonographic marker, uterocervical angle, correlates with risk of spontaneous preterm birth in a general population.STUDY DESIGN: We conducted a retrospective cohort study from May 2014 through May 2015 of singleton gestations between 16 0/7- 23 6/7 weeks undergoing transvaginal ultrasound for cervical length screening. Images were remeasured for uterocervical angle between the lower uterine segment and the cervical canal. Primary outcome was prediction of spontaneous preterm birth
