目的:探讨联合经腹与经会阴超声诊断前置胎盘的价值。方法:对临床怀疑前置胎盘的孕妇行经腹与经会阴联合超声检查,并与分娩所见对照。结果:经腹诊断负荷率明显低于经腹与经会阴联合检查(P<0.05)。结论:经腹和经会阴超声联合可提高前置胎盘的诊断符合率。
Objective: To investigate the value of combined transabdominal and perineal ultrasound in the diagnosis of placenta previa. Methods: Pregnant women with suspected placenta previa were subjected to combined perineal and perineal ultrasonography and compared with that of childbirth. Results: The transabdominal diagnostic load was significantly lower than the transabdominal and transperineal combined examination (P <0.05). Conclusion: Transabdominal and transperineal ultrasound can improve the diagnostic accuracy of placenta previa.
