目的 :探讨胎膜血管前置的产前超声诊断方法及意义。方法 :选取2015年5月—2016年5月间于我院进行产前超声检查的8520例孕妇为研究对象,回顾性分析其超声诊断资料,追踪其妊娠结局。结果:8520例受检者中,临床确诊为血管前置的患者共17例,血管前置发生率为0.02%,超声诊断结果显示18例血管前置患者,诊断准确率为94.44%,其中1例因胎头低而误诊,误诊率为5.56%;17例胎盘前置患者均行剖宫产,母婴健康,未发生围产期死亡病例或结构畸形情况。结论 :产前超声诊断可有效识别胎膜血管前置,可避免不良妊娠结局的发生,值得临床推广及应用。
Objective: To investigate the prenatal ultrasound diagnostic method of fetal vascular previa and its significance. Methods: From May 2015 to May 2016, 8520 pregnant women undergoing prenatal ultrasound examination in our hospital were selected as the research objects. Their diagnostic data were retrospectively analyzed and their pregnancy outcomes were tracked. Results: Of the 8520 subjects, 17 were diagnosed as pre-vascular and 0.02% were pre-vascular, and 18 were pre-vascular with ultrasonography. The diagnostic accuracy was 94.44%, of which 1 Misdiagnosis rate of 5.56% due to low fetal head, misdiagnosis rate of 5.56%; 17 cases of placenta previa patients undergoing cesarean section, maternal and child health, no perinatal deaths or structural deformity. Conclusion: Prenatal ultrasound diagnosis of fetal membranes can effectively identify the pre-vascular, can prevent the occurrence of adverse pregnancy outcomes, worthy of clinical promotion and application.
