目的:分析彩色多普勒超声对产前诊断胎盘血管前置的诊断价值。方法:选取从2014年1月至2016年1月,于东莞市第三人民医院收治的胎盘血管前置孕妇40例。采用彩色多普勒超声对所有孕妇进行产前诊断,观察胎盘血管前置检出率、孕妇分娩情况以及新生儿存活情况。结果:彩色多普勒超声检出率为92.50%(37/40),漏诊2.50%(1/40),误诊5.00%(2/40);选择阴道分娩孕妇占比17.50%(7/40),而选择剖宫产孕妇占比82.50%(33/40),二者相比,差异有统计学意义(P<0.05)。两种分娩方式的新生儿存活率及死亡率组间比较,差异无统计学意义(P>0.05)。结论:彩色多普勒超声能作为一种早期诊断胎盘血管前置的手段,具有较高的诊断符合率。
Objective: To analyze the diagnostic value of color Doppler ultrasonography in prenatal diagnosis of placenta previa. Methods: From January 2014 to January 2016, 40 pregnant women with placental precursors were enrolled in the Third People’s Hospital of Dongguan City. Prenatal diagnosis was performed on all pregnant women by color Doppler sonography. The detection rate of placenta previa, the delivery of pregnant women and the survival of neonates were observed. Results: The detection rate of color Doppler ultrasound was 92.50% (37/40), missed diagnosis of 2.50% (1/40), misdiagnosed 5.00% (2/40), and vaginal delivery of pregnant women accounted for 17.50% (7/40) , While the proportion of pregnant women choosing cesarean section accounted for 82.50% (33/40), the difference was statistically significant (P <0.05). There was no significant difference between the two groups in neonatal survival rate and mortality rate (P> 0.05). Conclusion: Color Doppler ultrasound can be used as an early diagnosis of placental vascular anterior approach, with a high diagnostic accuracy.
