彩色多普勒超声对前置血管的诊断及临床价值

目的:评价彩色多普勒超声(CDFI)对前置血管的诊断价值及临床意义。方法:回顾分析19例前置血管彩色多普勒超声的声像图表现及母儿结局,并进行超声分型分析。结果:16例前置血管患者的彩色多普勒超声诊断与临床和病理诊断结果一致,诊断符合率84.2%;漏诊3例(占15.8%)。19例前置血管患者中彩色多普勒超声检出脐带帆状附着型10例,0副胎盘型4例,双叶胎盘型3例,脐带胎盘边缘附着型2例。19例前置血管孕妇剖宫产16例,阴道分娩3例;活婴23例,死胎7例;母亲全部康复出院。结论:彩色多普勒超声对前置血管的诊断准确率较高,能降低围生儿死亡率,可作为前置血管的首选检查方法。

Diagnosis and Clinical Value of CDFI in the Treatment of Vasa Previa

Objective: To evaluate the diagnosis and clinical value of color doppler flow imaging(CDFI) in the treatment of vasa previa.Method: A retrospective analysis was made on the CDFI ultrasonographical features of 19 cases patients with vasa previa and also made on the situation of mother and baby,then carrying out ultrasound classification.Result: There were 16 cases vasa previa patients whose CDFI diagnosis was in conformity with the clinical and pathological diagnosis.The coincidence rate was 84.2%.There were 3 cases patients who belonged to missed diagnosis(15.8%).Of 19 cases patients with vasa previa checked by CDFI,10 cases were velamentous insertion of umbilical cord,4 cases were accessory placenta,3 cases were placenta bipartite and 2 cases were marginal insertion of umbilical cord.Of 19 cases pregnant women with vasa previa,16 cases were conducted cesarean birth and 3 cases gave birth by natural labor,including living babies of 23 cases and stillbirths of 7 cases.All mothers recovered and left the hospital.Conclusion: It is accurate that the vasa previa is diagnosed by CDFI,which can drop the death rate of fetus.Therefore,it shall be the first-choice method in the examination of vasa previa.
