【摘要】 目的探讨产前超声诊断不同类型前置胎盘的临床应用价值。方法选取我院经产前超声诊断为前置胎盘孕妇228例,对比产后不同类型前置胎盘的诊断准确率,分析其临床特征、妊娠结局等情况。结果产前超声诊断228例前置胎盘孕妇中,准确诊断224例(98.2%),分别为完全性前置胎盘75例,部分性前置胎盘组71例,边缘性前置胎盘78例;误诊4例。其中以完全性前置胎盘危害最为严重,其胎盘植入、产后出血及新生儿发生窒息的情况较部分性和边缘性前置胎盘发生率高,差异均有统计学意义(均P<0.05)。结论产前超声诊断不同类型前置胎盘对产前临床处理和预后提供了重要依据和指导意义。更多还原

【Abstract】 Objective To explore the clinical application value of prenatal ultrasound in diagnosis of different types of placenta praevia. Methods Two hundred and twenty-eight pregnant women with placenta praevia diagnosed by prenatal ultrasound were selected. The coincidence rate of prenatal ultrasound with the postpartum clinical diagnosis was compared. The clinical characteristics,pregnancy outcome etc. were analyzed. Results In 228 cases with placenta praevia,there were 75 cases of complete placenta praevia,71 cases of partial placenta praevia,78 cases of marginal placenta praevia. The general coincidence rate of prenatal ultrasound was 98.2%. The complete placenta praevia was the most serious,the incidence rate of placenta accrete,postpartum hemorrhage and neonatal asphyxia was higher than that of other types of placenta praevia,there was significant difference(P < 0.05). Conclusion Prenatal ultrasound diagnosis of different types of placenta praevia provides important reference and guidance significance for prenatal clinical treatment and prognosis.更多还原
