Abstract

Objective: Placenta previa complicates 0.3-0.5% of pregnancies and can cause sudden antepartum massive hemorrhage (APH). Previous studies have indicated that cervical length (CL) measured by transvaginal ultrasonography may be a predicting parameter for APH in patients with placenta previa; however, conflicting data exist. Thus, we investigated the association between CL and APH in patients with placenta previa.

Methods: In total, 129 singleton pregnant women with placenta previa, who delivered at our institution from January 2010 to December 2016, were included in this study. The shortest CL measured throughout gestation was used for analysis, and we defined CL less or more than 30 mm as short or normal CL, respectively. We performed univariate and multivariate analyses, and a receiver-operating characteristics (ROC) curve was plotted to determine the cut-off CL value to predict APH.

Results: APH occurred in 26 patients. The adjusted odds ratio for APH was 3.80 (95% CI, 1.36-10.65) in patients with short CL. ROC analysis was performed to determine a cut-off CL value of 35 mm to predict APH, with a sensitivity of 80.7% and a specificity of 60.2%.

Conclusions: Our data indicated that CL measurements may be useful in determining patients at high risk of APH.

宫颈长度是前置胎盘患者产前出血的有效预测因子吗?

前言:目的:前置胎盘并发症发生率为0.3% ~ 0.5%，可引起突发性产前大出血(APH)。既往研究提示经阴道超声测量宫颈长度(CL)可作为前置胎盘患者APH的预测参数;然而，存在矛盾的数据。因此，我们研究了前置胎盘患者CL和APH之间的关系。方法:选取2010年1月至2016年12月在我院分娩的129例前置胎盘单胎孕妇。在整个妊娠期间测量的最短CL用于分析，我们将CL小于或大于30 mm分别定义为短CL或正常CL。我们进行了单因素和多因素分析，并绘制了受试者工作特征(ROC)曲线，以确定预测APH的截止CL值。结果:26例患者发生APH。在短期CL患者中，APH的校正优势比为3.80 (95% CI, 1.36-10.65)。ROC分析确定35 mm的截止CL值预测APH，敏感性为80.7%，特异性为60.2%。结论:我们的数据表明CL测量可用于确定APH高危患者。
