目的探讨二维超声联合彩色多普勒超声(彩超)对疤痕子宫合并前置胎盘植入诊断的临床运用价值。方法分析福建省妇幼保健院住院的疤痕子宫合并前置胎盘孕妇,产前二维超声联合彩超像图特征和表现。分析二维超声联合彩超对该类孕妇胎盘植入产前诊断的敏感性和特异性。结果共纳入209例疤痕子宫合并前置胎盘孕妇,病理确诊胎盘植入38例,其中产前二维联合彩超诊断有31例,7例超声未确诊,2例产前二维联合彩超诊断胎盘植入,但是病理未确诊。二维超声联合彩超诊断疤痕子宫合并前置胎盘植入的敏感性为81.6%、特异性为98.8%、阳性预测值为93.9%、阴性预测值为96.0%。诊断符合率为95.7%。结论二维超声联合彩超对产前诊断疤痕子宫合并前置胎盘植入具有较高的运用价值,可作为临床筛查的重要辅助检查方法。
Objective To investigate the clinical value of two-dimensional ultrasonography combined with color Doppler ultrasonography (Doppler ultrasonography) in the diagnosis of uterine scarring combined with placenta previa. Methods The characteristics and manifestations of pregnant women with preimplantation scar and uterus with placenta previa combined with color Doppler echocardiography in Fujian Province MCH hospital were analyzed. To analyze the sensitivity and specificity of two-dimensional ultrasound combined with color Doppler ultrasonography in prenatal diagnosis of placenta accreta. Results A total of 209 cases of uterus with placenta previa were enrolled in this study. 38 cases were diagnosed as placenta accreta by pathology. Among them, 31 cases were diagnosed by prenatal two-dimensional combined color Doppler ultrasound, 7 cases were diagnosed by ultrasound, 2 cases were diagnosed by prenatal two- Into, but the pathology is not diagnosed. The sensitivity and the specificity of two-dimensional ultrasonography combined with color Doppler ultrasound in the diagnosis of uterine scar with placenta previa were 81.6%, 98.8%, 93.9%, and 96.0%, respectively. The diagnostic coincidence rate was 95.7%. Conclusions Two-dimensional ultrasonography combined with color Doppler ultrasonography has a high value for prenatal diagnosis of uterine scarring combined with placenta previa. It can be used as an important auxiliary examination method for clinical screening.
