摘要
目的:探究分析产前超声技术对凶险型前置胎盘合并胎盘植入的检查与诊断作用。方法:选择2020年1月到2021年12月作为研究时间段,抽取这一期间到本院妇产科接受产检的120例凶险型前置胎盘孕妇纳入观察样本对象,所有的孕妇均接受彩色多普勒超声技术检查,以手术病理检查结果作为黄金标准,分析所有孕妇彩色多普勒超声技术检查的灵敏度、特异度、准确性,分析彩色多普勒超声技术检查的特征,总结凶险型前置胎盘合并胎盘植入的具体超声图像特征。结果:彩色多普勒超声技术检查的灵敏度为91.67%,特异度为87.50%,准确性为90.00%。93例孕妇子宫肌层<2mm、胎盘增厚、宫颈膨大的发生率分别为77.50%、67.5%、35.00%。凶险型前置胎盘合并胎盘植入孕妇的胎盘与子宫壁界限模糊、子宫肌层出现胎盘样回声、胎盘增厚、胎盘内部存在血池、胎盘内存在腔隙血流、胎盘后有间隙、子宫壁出现局限性回声外凸、子宫壁和膀胱壁血流丰富紊乱的发生率显著高于凶险型前置胎盘未合并胎盘植入的孕妇,差异存在统计学意义(P<0.05)。结论:产前彩色多普勒超声技术诊断凶险型前置胎盘合并胎盘植入的准确率比较高,对于优化母婴结局而言非常重要,具有较高的临床推广价值,可以作为临床产科主要的影像学产检手段,临床应不断加强研究,以进一步提高彩色多普勒超声技术的准确率。
Objective: To investigate and analyze the role of prenatal ultrasound in the detection and diagnosis of dangerous placenta previa with placenta accreta. Methods: The period from January 2020 to December 2021 was selected as the study period. 120 dangerous pregnant women with placenta previa who had undergone prenatal examination in the department of obstetrics and gynecology of our hospital during this period were selected as the observation samples.All pregnant women received the color Doppler ultrasound examination. Taking the results of surgical and pathological examination as the gold standard, the sensitivity, specificity and accuracy of color Doppler ultrasonography in all pregnant women were analyzed.. Then analyzing the characteristics of color Doppler ultrasonography and summarizing the specific ultrasonic image characteristics of dangerous placenta previa with placenta accreta. Results: The sensitivity,specificity and accuracy of color Doppler ultrasound were 91.67%, 87.50% and 90.00% respectively. The incidences of myometrium < 2mm, placenta thickening and cervical enlargement in 93 pregnant women were 77.50%, 67.5% and 35.00% respectively. The incidence of borderline blurring between placenta and uterine wall, placental echo in uterine muscle layer, placental thickening, blood pool in placenta, lacunar blood flow in placenta, space behind placenta,localized echo protrusion in uterine wall, and rich and disordered blood flow in uterine wall and bladder wall in pregnant women with dangerous placenta previa and placenta accreta was significantly higher than that in pregnant women with dangerous placenta previa but without placenta accreta. The difference was statistically significant(P<0.05). Conclusion:The accuracy of prenatal color Doppler ultrasound in the diagnosis of dangerous placenta previa with placenta accreta is relatively high, which is very important for optimizing maternal and infant outcomes, and has high clinical promotion value. It is worthy of being used as the main means of imaging prenatal examination in clinical obstetrics. Clinical research should be strengthened to further improve the accuracy of color Doppler ultrasound technology.
