经阴道三维超声测定子宫内膜容积对异位妊娠的预测价值

Predictive Value of Transvaginal Three-dimensional Ultrasonography for Endometrial Volume in Ectopic Pregnancy

目的:探讨经阴道三维超声测定子宫内膜容积对异位妊娠的预测价值。方法:应用经阴道三维超声对120例疑似异位妊娠患者,进行子宫内膜容积的检测。根据子宫内膜容积将患者分为三组(<2 ml、2~4 ml、>4 ml),比较各组的妊娠结局。根据正常妊娠与异位妊娠分为两组,比较两组的子宫内膜容积。结果:120例患者中,临床妊娠97例。子宫内膜容积<2 ml组、2~4 ml组、>4 ml组的妊娠结局比较,差异均无统计学意义(P>0.05)。正常妊娠组和异位妊娠组子宫内膜容积比较,差异无统计学意义(ROC曲线下面积=0.539)。子宫内膜容积与异位妊娠有相关性,但非完全线性相关(rs=0.724 8)。结论:子宫内膜容积不能完全预测异位妊娠,但对于临床判断是否为异位妊娠具有一定的指导意义。

Objective： To investigate the predictive value of transvaginal three-dimensional ultrasound in the determination of endometrial volume in ectopie pregnancy.Method： The volume of endometrium was measured in 120 patients with suspected ectopic pregnancy by transvaginal three-dimensional ultrasound.According to endometfial volume, the patients were divided into three groups（〈2 ml, 2-4 ml, 〉4 ml）, and the pregnancy outcomes were compared. According to normal pregnancy and ectopie pregnancy, the patients were divided into two groups, and endometrial volume were compared.Result： There were 97 cases of clinical pregnancy among the 120 patients.Compared the pregnancy outcomes between the endometrial volume 〈2 ml group, 2~4 ml group and 〉4 ml group, there was no significant differenee（P〉O.O5）.There was no significant difference in endometrial volume between normal pregnancy and eetopie pregnancy（areas under the ROC curve=O.539）.Endometrial volume was associated with ectopic pregnancy, but not entirely linear（rs=0.724 8）.Conclusion： The volume of endomctrium can not predict the ectopic pregnancy, but it has some guiding significance for the clinical diagnosis of ectopic pregnancy
