目的分析二维超声成像对胎盘残留诊断的临床应用价值。方法对2008年1月-2014年1月在医院进行生产且怀疑有胎盘残留的25例患者进行二维超声检查,将诊断结果与术后病理结果进行比对分析。结果二维超声依据宫腔体积诊断胎盘残留的准确率、灵敏度均高于二维超声依据子宫体积,差异均有统计学意义(P<0.05)。依据二维超声依据宫腔体积对分娩后第28天或28 d后出血患者诊断胎盘残留的准确率和灵敏度均高于对分娩后不足28 d出血患者的诊断,差异均有统计学意义(P<0.05)。结论依据二维超声测量宫腔体积诊断胎盘残留的准确率高于依据子宫体积,且对分娩后第28天或28 d以后出血患者诊断胎盘残留的准确率高于不足28 d出血的患者。
Objective To analyze the clinical value of two-dimensional ultrasonography in the diagnosis of placental residue. Methods Twenty-five patients who were hospital-based and suspected to have placental residue from January 2008 to January 2014 were examined by two-dimensional ultrasonography. The diagnostic results were compared with postoperative pathological results. Results Two-dimensional ultrasound based on intrauterine volume diagnosis of placental residual accuracy, sensitivity were higher than two-dimensional ultrasound based on uterine volume, the difference was statistically significant (P <0.05). The accuracy and sensitivity of two-dimensional ultrasound in diagnosing placental residue on the 28th day or 28th day after childbirth were higher than those on the bleeding less than 28 days after childbirth according to the volume of uterine cavity, the differences were statistically significant (P <0.05). Conclusions The accuracy of two-dimensional ultrasonography in the diagnosis of placenta accreta is higher than that of uterine volume, and the accuracy of diagnosis of placental residue after bleeding on the 28th day or 28th day after delivery is higher than that of the 28th day.
