经阴道超声测量子宫宫腔团块的厚度和体积诊断不全流产的价值

Applicable value of measuring endometrial thickness and volume by transvaginal ultrasonography for the diagnosis of incomplete miscarriage

目的评估采用超声测量方法诊断临床怀疑不全流产患者宫腔残留妊娠物的应用价值。方法 回顾性分析2013年1月~2015年6月在我院临床怀疑不全流产并行清宫术的患者共145例,经阴道超声测量子宫内异常回声团块的厚度及体积,清宫术后的组织送病理学检查。对比研究宫内异常回声团块的厚度、体积与病理学结果的相关性。结果 145例患者中,102例（70.3%）病理学检测发现绒毛膜组织,43例（29.7%）仅发现蜕膜组织。未发现有意义的团块厚度或体积的参考值,可以用来区分妊娠残留物和蜕膜组织。结论 超声测量子宫内异常团块的厚度或体积,不是诊断不全流产的有效指标。

Objective To access the applicable value of diagnosing retained products of conceptions（RPOC） by transvagi- nal ultrasonography in 145 women with clinical diagnosis of incomplete miscarriage. Methods A retrospective study was performed to analyze the data in 145 female patients treated during the period from Jan 2013 to June 2015.These women were suspected that there were retained tissue in uterus after incomplete miscarriage.The measurement of en- dometrial thickness and volume were acquired by transvaginal ultrasonography. And all the tissues in uterus were for pathological examination. The relationship among endometrial thickness, volume and pathological examination were an- alyzed. Results Among 145 patients,the pathological results of 102（70.3%） were chorionic villi,while the left 43 （29.7%） were decidua.There was no identifiable cut-off value of endometrial thickness and volume that could be used to differ- entiate retained products of conception and decidua. Conclusion Ultrasound parameters of endometrial thickness and volume are not good diagnostic marker for diagnosing an incomplete miscarriage.
