摘要
目的探讨联合应用腹部超声、会阴超声、阴道超声对前置胎盘的诊断价值。方法腹部超声观察胎儿生长情况及胎盘的附着部位,如果附着部位为后壁、侧壁,胎头位置过低,胎盘下缘与宫颈内口关系显示不清,临床高度怀疑前置胎盘时,则联合使用会阴超声和阴道超声。结果联合超声的使用,能较准确清晰地显示宫颈内口及其与胎盘下缘的关系,从而提高前置胎盘诊断的准确率。结论联合超声检查能为临床提供可靠信息,提高前置胎盘的诊断准确率,减少母婴的死亡率。
Objective To explore the diagnostic value of combined ultrasonography including transabdominal, transperineal and transvaginal uhrasonography for placenta previa. Methods Transabdoninal ultrasonography was used to observe the fe- tal growth and the placenta position. If there was no concreate relationship between the lower edge of placenta and the in- ner cervix, but the placenta previa was highly suspected, transperineal and transvaginal uhrasonography should be used combinedly. Results Combined ultrasonography could clearly observe the inner cervix and the lower edge of placenta and could increase the diagnostic rate of placenta previa. Conclusion Combined ultrasonography can provide reliable clinical information, improve the diagnostic rate of placenta previa and minimize the death rate of newborns and mothers.
