产前超声诊断血管前置的临床价值

Clinical value of prenatal ultrasound in diagnosis of vasa previa

目的探讨产前超声检查诊断血管前置的临床价值。方法回顾性分析接受产前超声检查的65 230例孕妇的超声声像图资料。统计产前超声诊断血管前置的准确率,随访血管前置产妇的分娩方式和围产儿结局。结果产前超声初次检查拟诊血管前置53例,晚孕期复查排除10例,最终超声明确诊断43例。经临床证实41例(发生率41/65 230,0.06%),其中中孕期(15~28周)筛查加晚孕期(28~40周)复诊诊断血管前置的准确率为100%(28/28),仅行晚孕期检查诊断准确率为86.67%(13/15)。41例血管前置孕妇全部接受剖宫产手术,胎儿均存活。结论产前超声诊断血管前置具有较高的临床应用价值。

Objective To explore the clinical value of prenatal ultrasound in diagnosis of vasa previa. Methods The images of 65 230 pregnant women who underwent prenatal ultrasound examination were analyzed retrospectively. The accuracy of prenatal ultrasound in diagnosis of vasa previa was calculated. The delivery modes of all pregnant women and outcomes of all perinatal infants with vasa previa diagnosis were followed up. Results Fifty-three vasa previa cases were diagnosed during the first examination using prenatal ultrasound and 10 cases were eliminated during reexamination in late pregnancy, so 43 cases were diagnosed. Finally 41 cases(41/65 230, 0.06%) were clinically confirmed. The accuracy of middle pregnancy screening(15-28 weeks) and late pregnancy(28-40 weeks) reexamination was 100%(28/28), and the accuracy of late pregnancy was 86.67%(13/15). Cesarean section surgery was performed in all 41 pregnant women, and all fetuses survived. Conclusion Prenatal ultrasound has a high value of prenatal ultrasound in diagnosis of vasa previa.
