产前超声诊断中晚期孕妇胎儿血管前置的价值探析

目的探析产前超声诊断中晚期孕妇胎儿血管前置的价值。方法回顾性分析我院妇产科22例产前疑诊胎儿血管前置孕妇中晚期超声检查与手术病理临床资料,以手术病理结果作为金标准,评价产前超声检查对中晚期孕妇胎儿血管前置的诊断效能。结果手术病理结果显示,22例疑诊孕妇中16例为胎儿血管前置,经产前超声诊断检出例,孕中晚期超声诊断胎儿血管前置的灵敏度为87.5%(14/16),特异度为66.67%(4/6),准确率为81.81%(18/22),阳性预测值为87.5%(14/16),阴性预测值为66.67%(4/6)。结论于孕中晚期进行产前超声可有效对胎儿血管前置进行提前诊断。

Analysis of Value of Prenatal Ultrasound in the Diagnosis of Fetal Vasa Previa in Pregnant Women in Second and Third Trimester

Objective To analyze the value of prenatal ultrasound in the diagnosis of fetal vasa previa in pregnant women in second and third trimester. Methods The clinical data of ultrasonography and surgical pathology of 22 pregnant women in second and third trimester who were prenatally diagnosed as fetal vasa previa in the Department of Obstetrics and Gynecology in our hospital were retrospectively analyzed. Surgical pathological results were taken as gold standard to evaluate the diagnostic efficacy of prenatal ultrasound examination for fetal vasa previa in pregnant women in second and third trimester. Results The results of surgical pathology showed that 16 cases among 22 suspected pregnant women were with fetal vasa previa. The sensitivity, specificity, accuracy rate, positive predictive value and negative predictive value of prenatal ultrasound diagnosis of fetal vasa previa were 87.5%(14/16), 66.67%(4/6), 81.81%(18/22), 87.5%(14/16) and 66.67%(4/6). Conclusions Prenatal ultrasound in second and third trimester can effectively diagnose the fetal vasa previa.
