摘　　要：目的:探究产前经腹灰阶联合彩色血流超声多参数对胎盘植入性疾病的诊断效能。方法:2019年11月-2021年12月于我院收治的产前超声诊断为前置胎盘的孕妇共计62例,其中44例超声诊断合并了胎盘植入的孕妇。所有孕妇产前均进行经腹灰阶检查、经腹彩色超声检查和二者联合检查胎盘植入性疾病,通过分析胎盘植入性疾病筛查结果,评价产前超声经腹灰阶联合彩色血流超声多参数对胎盘植入性疾病的筛查效能。结果:(1)通过灰阶超声诊断检出胎盘植入的灵敏度为73.42%,特异度为86.54%;(2)通过彩色超声诊断检出胎盘植入的灵敏度为76.89%,特异度为89.07%;(3)经腹灰阶联合彩色血流超声多参数诊断检出胎盘植入的灵敏度为87.79%,特异度为90.36%;(4)经腹灰阶检查、经腹彩色超声检查和二者联合检查对胎盘植入性疾病筛查阳性率分别为56.45%、62.90%和67.74%,二者联合检查对产前胎盘植入性疾病筛查阳性率显著高于经腹灰阶检查和经腹彩色超声检查(P<0.05)。(5)二者联合检查的敏感度为72.26%,特异度为90.54%,阳性比为95.55%,诊断比值比为78.89%。结论:产前经腹灰阶联合彩色血流超声多参数对胎盘植入性疾病的诊断有较高的灵敏度和特异度,值得临床推广应用。Objective:To explore the diagnostic efficacy of prenatal transabdominal gray scale combined with color flow ultrasound for placental implantation diseases.Methods:A total of 62 pregnant women with placenta previa diagnosed by prenatal ultrasound in our hospital from November 2019--December 2021,including 44 pregnant women with placenta implantation.All pregnant women underwent transabdominal gray-scale examination,transabdominal color ultrasound and their combination to detect placental implantation diseases.The screening efficiency of transabdominal gray-scale ultrasound combined with color blood flow ultrasound on placental implantation diseases was evaluated by analyzing the screening results of placental implantation diseases.Results:(1)The sensitivity and specificity of detecting placental implantation by gray-scale ultrasound were 73.42%and 86.54%;(2)the sensitivity and specificity of detecting placental implantation by color ultrasound were 76.89%and 89.07%;(3)the sensitivity and specificity of detecting placental implantation by abdominal gray-scale combined with color blood flow ultrasound were 87.79%and 90.36%;(4)The positive rates of transabdominal gray scale examination,transabdominal color ultrasound examination and their combined examination in the screening of placental implantation diseases were 56.45%,62.90%and 67.74%respectively.The positive rates of the two combined examinations in the screening of prenatal placental implantation diseases were significantly higher than those of transabdominal gray scale examination and transabdominal color ultrasound examination(P<0.05).(5)The sensitivity was 72.26%,the specificity was 90.54%,the positive ratio was 95.55%,and the diagnostic odds ratio was 78.89%.Conclusion:Transabdominal gray scale combined with multi-parameter color flow ultrasound has high sensitivity and specificity in the diagnosis of prenatal placenta implantation diseases,which is worthy of clinical application.
