经阴道二维和三维超声对剖宫产术后子宫疤痕部位妊娠的诊断价值

摘要

目的 评价经阴道二维、三维超声在诊断剖宫产术后子宫疤痕部位妊娠(简称切口妊娠)的价值.方法 回顾分析2015-2016年经阴道二维超声诊断为子宫前壁下段剖宫产切口妊娠的病例30例,在此基础上进行阴道三维超声诊断,所有病例均行磁共振检查核实.分析阴道二维、三维超声诊断为切口妊娠的价值.结果 有1例经阴道二维超声诊断为切口处及宫腔下段孕囊部分植入型,后经阴道三维超声诊断为切口处孕囊完全植入型,其余分型与三维超声诊断一致.磁共振检查结果与阴道三维超声一致.三者诊断分型符合率比较差异无统计学意义(P>0.05).结论 阴道三维超声可更为直观地显示病灶位置、范围、切口受累情况,较经阴道二维超声具有更加丰富的诊断信息.%Objective To evaluate the value of transvaginal two-dimensional and three-dimensional ultrasound in diagnosis of cesarean scar pregnancy (incision area pregnancy ) after cesarean section .Methods Thirty cases of cesarean incision pregnancy at lower section of uterine anterior wall diagnosed by transvaginal two-dimensional ultrasound during 2015-2016 were retrospectively analyzed .On this basis ,all cases conducted transvaginal three-dimensional ultrasound and were verified by magnetic resonance(MR) examination .Then the values of transvaginal two-dimensional and three-dimensional ultrasound in diagnosis of incision area preg-nancy were analyzed .Results One case was diagnosed as the incision site and partial implantation of pregnant capsule by transvagi-nal two-dimensional ultrasound ,and then diagnosed as the complete implantation of pregnant capsule at incision site ,the other types were consistent to the diagnosis by the three-dimensional ultrasound .The MR examination results were consistent to the those by three-dimensional ultrasound .The diagnosis typing coincidence rate had no statistical difference among the three methods ( P>0 .05) .Conclusion Transvaginal three-dimensional can more intuitively display the lesion′s position ,range ,incision involvement sit-uation ,while transvaginal two-dimensional ultrasound has more plentiful diagnostic information .
