凶险型前置胎盘合并胎盘植入的产前超声诊断及临床意义

Prenatal Ultrasonographic Diagnosis and Clinical Significance of Severe Placenta Previa with Placenta Accreta

目的:探讨凶险型前置胎盘合并胎盘植入的产前超声诊断及临床意义。方法:回顾性分析凶险型前置胎盘合并胎盘植入患者60例的临床资料,对所有患者进行产前超声诊断,分析诊断准确率、漏诊率、误诊率以及超声检查特点。结果:超声诊断准确率为91.67%,漏诊率为5.00%,误诊率为3.33%,与病理结果之间无明显差异(P>0.05)。结论:产前超声诊断凶险型前置胎盘合并胎盘植入具有无创性,可重复进行诊断检查,有助于疾病的早期诊断及防治,可有效降低产妇以及胎儿死亡概率,值得推广。

Objective：To investigate the prenatal diagnosis and its clinical significance of dangerous placenta previa with placenta accreta.Methods：The clinical data of 60 patients with malignant placenta previa and placenta accreta were retrospectively analyzed.All patients were diagnosed by prenatal ultrasound,and the diagnostic accuracy,missed diagnosis rate,misdiagnosis rate and the characteristics of ultrasonography were analyzed.Results：The accuracy rate of ultrasonic diagnosis was 91.67%,the rate of missed diagnosis rate was 5.00% and the rate of misdiagnosis was 3.33%.There was no significant difference in pathological results（P〉0.05）.Conclusion：Prenatal ultrasound diagnosis of perilous placenta previa combined with placenta accreta is noninvasive and can be diagnosed repeatedly,which is helpful to the early diagnosis and prevention of diseases,can effectively reduce the probability of maternal and fetal death,and is worthy of popularizing.
