摘要
目的 探讨产前胎盘血管前置诊断中彩色多普勒超声的临床价值。方法 选取2007年至2013年我院产检的孕产妇多普勒超声检查资料进行分析,分析血管前置的发生情况。结果 孕检73186例孕妇中血管前置发生28例,发生率为0.038%,经产前超声诊断确诊25例,检出率为89.29%,漏诊3例。3例漏诊的患者均在晚孕期行B型超声检查确诊,阴道分娩,胎儿死亡。合并帆状胎盘17例,合并副胎盘7例,合并多叶胎盘4例。结论 产前彩色多普勒超声检查能够有效诊断胎盘血管前置,具有较高的诊断符合率,能够作为早期诊断的有效方法 。
Objective:To explore the application value of color Doppler ultrasonography in the prenatal diagnosis of placenta previa in blood vessel.Method:Maternal doppler ultrasonography data in our hospital from 2011 to 2013 were selected and analyzed.The occurrence of vasa previa was analyzed and further diagnosised combine with the clinical operation.Result:There were 28 cases of vasa previa occurred, the incidence was 0.053% in 53186 cases of pregnant women in pregnancy test.Prenatal ultrasound diagnosed 25 cases, the positive rate was 89.29%, 3 cases were missed diagnosis. Color doppler ultrasonography in cervical sagittal cervical internal tubular vessels across the top,visible placental cord entrance section, the umbilical cord blood vessels near or across the endocervix,the placental edge was placenta cord entrance.3 cases of missed diagnosis for patients were given ultrasound examination for type B in late pregnancy,vaginal delivery,and fetal death. The merger of velamentous placenta were 17 cases,with vice placenta were 7 cases, 4 cases were complicated with placenta extract.Conclusion:Antenatal examination may be useful for diagnosis of placental vasa previa by color Doppler ultrasound, and to achieve a higher diagnosis rate, and can be used as early diagnostic method.
