目的:探讨在产前前置胎盘的诊断中经腹联合经会阴超声的临床价值。方法:选取78例于2012年8月至2015年8月期间在我院确诊为前置胎盘的患者,所有患者先进行经腹超声检查,之后行经会阴超声检查,观察经腹联合经会阴超声检查及单独经腹超声检查前置胎盘的诊断符合率。结果:经腹超声诊断前置胎盘符合者67例,漏诊7例,误诊4例,联合会阴检查后,其中8例得以纠正,但仍有3例漏诊,经腹联合经会阴超声与单独经腹超声诊断前置胎盘的准确率分别为96.2%、85.9%,前者明显高于后者(P<0.05)。结论:临床在采用经腹超声筛查前置胎盘有疑虑或无法充分显示时,应联合经会阴超声检查,可相互补充,扬长避短,从而提高产前前置胎盘的诊断率,以利于医师及时制定治疗方案,减少母婴风险。
Objective: To investigate the clinical value of transabdominal combined transperineal ultrasonography in the diagnosis of prenatal placenta accreta. Methods: Seventy-eight patients diagnosed as placenta previa in our hospital from August 2012 to August 2015 were enrolled in this study. All patients underwent transabdominal ultrasonography before transperineal ultrasonography. The transabdominal ultrasonography And transabdominal ultrasonography alone placenta previa diagnosis coincidence rate. Results: In the diagnosis of placenta accreta by trans-abdominal ultrasonography in 67 cases, missed diagnosis in 7 cases and misdiagnosis in 4 cases. After combined perineal examination, 8 cases were corrected, but there were still 3 cases of missed diagnosis, transabdominal combined transperineal ultrasound and single transabdominal ultrasound The accuracy of ultrasonic diagnosis of placenta previa were 96.2%, 85.9%, the former was significantly higher than the latter (P <0.05). Conclusions: When using the transabdominal ultrasound screening of placenta previa doubt or can not be fully displayed, should be combined by the perineal ultrasound examination, can complement each other, avoid weaknesses, thereby increasing the prenatal diagnosis of placenta previa, in order to facilitate the timely development of physicians Treatment options to reduce maternal and child risks.
