经腹部和经阴道彩色多普勒超声在流产后宫内残留物诊断中的应用比较

目的对经腹部超声和经阴道超声在妊娠早期流产后宫腔内残留物诊断中的应用进行比较分析。方法选取2014年1月至2015年12月，于妊娠早期来我院行妊娠终止术110例．术后超过2周仍有阴道出血的患者．对其进行经腹部及经阴道彩色多普勒超声检查．观察宫腔内有无异常回声及彩色血流情况．并对其诊断价值进行分析。结果应用经阴道彩色多普勒超声．比经腹部超声能更清晰显示宫内异常回声的部位、大小及不同的声像图表现．残留物基底部堤局部宫壁组织内血流信息，可发现微小残留物．诊断准确率较经腹部高，漏诊率较经腹部低．差异具有统计学意义（P〈0．05）。结论对于产后宫内残留物诊断应用经阴道超声的诊断准确率高，漏诊比例低，能及时指导治疗，预防并发症的发生。

Objective to compare and analyze 1he application of abdominal uhrasound and transvaginal ultrasound in lhe diagnosis of early postpartum intrauterine residue. Methods A retrospective analysis of 110 cases that cboosed termination of pregnancy In early pregnancy in our hospital From January 2014 to December 2015, which still had vaginal bleeding after surgery more than 2 weeks, Througb the abdominal and transvaginal color Doppler ultrasound examination, observation the uterine cavity with abnormal echo and color Doppler flow, and analysis the diagnostic value. Results compared the abdominal uhrasound, application of transvaginal color Doppler ultrasound can be clearer display abnormal intrauterine echo location, size and different sonographic appearance and information of blood flow in the basal part of the residue and local uterus wall, found that small residues. The diagnoslic accuracy rate is higher, missed diagnosis rate is lower and the difference is statistically significant （P〈0.05）. Conclusion For tbe diagnosis of postpartum in trauterine residue, the application of transvaginal ultrasound has higher diagnostic accuracy rate, lower missed diagnosis rate, can guide treatment in time to prevent tbe occurrence of complications.
