摘　　要：目的探讨超声诊断前置胎盘及其合并症的方法和临床应用价值。方法收集2010年1月—2011年12月产前超声诊断前置胎盘与分娩后经临床证实前置胎盘的孕妇资料,进行回顾性分析。结果孕晚期超声诊断前置胎盘138例,均进行剖宫产术,手术结果证实138例均为前置胎盘,但随访中发现漏诊前置胎盘合并胎盘植入2例,前置胎盘合并胎盘粘连12例超声均未提示。结论产前超声诊断前置胎盘符合率较高,为临床诊断和治疗提供了可靠的依据,但超声对前置胎盘合并胎盘粘连和植入等合并症的诊断有待于进一步提高。Objective To assess the clinical value of prenatal ultrasound diagnosis in placenta previa and its complications.Methods The clinical and prenatal ultrasound data of placenta previa were studied and analyzed retrospectively from January 2010 to November 2011 in our hospital.Results All the 138 cases of placenta previa diagnosed by third trimester ultrasound had cesarean section and confirmed.But 2 missed diagnosis of placenta previa with placenta accreta were found by follow-up.12 cases of placenta previa with placenta adhesion were missed diagnosis by ultrasound.Conclusion The accuracy rate of ultrasound diagnosis of placenta previa is high.It can provide reliable data for clinic.But the ultrasound diagnosis of placenta previa with placenta accrete,placenta adhesion and other complications should be improved.
