目的:探讨阴道B超下子宫内膜厚度和试管婴儿临床妊娠之间的关系。方法:随机选择2014年6月至2016年3月肇庆西江医院生殖中心收治的100例进行体外受精-胚胎移植患者,通过回顾分析法将其分为妊娠组(35例)与非妊娠组(65例),分析阴道B超下子宫内膜厚度和试管婴儿临床妊娠之间的关系。结果:妊娠组中35例患者均妊娠成功;其中患者的绒毛膜促性腺激素(HCG)注射日、取卵日的内膜厚度等与妊娠之间没有任何关系;而内膜厚度<7 mm的患者则没有出现妊娠等情况;内膜厚度>11 mm的患者妊娠明显上升;可见,HCG注射日的内膜类型与妊娠没有任何联系(P>0.05);而取卵日的内膜类型和妊娠具有密切的关系(P<0.05);因此可以利用阴道B超下子宫内膜厚度来预测妊娠。结论:在阴道B超下,通过子宫内膜厚度可以有效预测试管婴儿的成功率。
Objective: To explore the relationship between vaginal B-suberymal endometrial thickness and IVF clinical pregnancy. Methods: A total of 100 in vitro fertilization and embryo transfer patients who were admitted to the reproductive center of Zhaojiang Xijiang Hospital from June 2014 to March 2016 were randomly selected and divided into three groups according to retrospective analysis: pregnancy group (35 cases) and non-pregnancy group (65 cases) Cases), analysis of vaginal B ultrasound endometrial thickness and IVF clinical pregnancy relationship. Results: All the 35 pregnant women in pregnancy group had successful pregnancy. There was no relationship between HCG injection day, the thickness of intima on ovulation day and pregnancy, while the thickness of intima was <7 mm The patient did not have pregnancy and so on; in patients with endometrial thickness> 11 mm pregnancy increased significantly; visible, HCG injection of endometrial type has no relationship with pregnancy (P> 0.05); while the date of ovulation endometrial type and pregnancy (P <0.05); therefore, vaginal B-submucosal endometrial thickness can be used to predict pregnancy. Conclusion: In vaginal B ultrasound, the success rate of IVF can be effectively predicted by the thickness of endometrium.
