【摘要】:目的:应用经阴道三维超声(3-dimentional transvaginalultrasound,3DTVU)测量纵隔子宫两侧内膜夹角大小,探讨两侧内膜夹角与纵隔子宫成形术后纵隔残余的关系,以及两侧内膜夹角与术后妊娠结局的关系。 方法:对72例流产、不孕的妇女子宫进行三维超声多平面成像。所有患者均行腹腔镜监视下宫腔镜纵隔切除术(transcervical resection of septum,TCRS)。在经3DTVU冠状切面上对子宫形态进行观察,测量宫底部切迹深度,纵隔长度,两侧内膜夹角大小。根据术前3DTVU测量两侧内膜夹角大小分组,小角度组(<90o)和大角度组(≥90o),术后3个月行经阴道三维超声复查,术后随访18个月妊娠结局。 结果:72例经3DTVU诊断纵隔子宫患者均行腹腔镜联合宫腔镜联合手术,手术诊断与术前3DTVU诊断相符合(符合率100%),其中完全性纵隔子宫22例,不全性纵隔子宫50例,大角度组19例,,小角度组53例。术后3个月经3DTVU复查,大角度组有9例出现纵隔残余,小角度组有10例出现纵隔残余,两组比较差异有统计学意义。大角度组和小角度组各有1例纵隔残余长度>1.0cm,行二次手术,大角度组有2例宫腔粘连,行宫腔镜确诊并行粘连松解术。术后随访18个月妊娠结局,随访率80.6%(58/72)。大角度组(17例)累计妊娠5例,活胎分娩2例,小角度组(41例)累计妊娠22例,累计活胎分娩14例。应用Kaplan-Meier法计算两组18个月累计妊娠率和活胎分娩率,并使用log-rank检验对比两组曲线差异。大角度组和小角度组累计妊娠率分别33.9%和55.8%,两组比较差异无统计学意义(χ2=1.098,P=0.295);大角度组和小角度组累计活胎分娩率分别为16.4%和37.1%,两组比较差异无统计学意义(χ2=3.067,P=0.080)。 结论:3DTVU可获取满意的纵隔子宫冠状面图像,准确测量宫底切迹深度、纵隔长度及两侧内膜夹角,为准确诊断纵隔子宫提供更多信息。大角度纵隔子宫术后易发生纵隔残余。纵隔子宫两侧内膜夹角的大小对妊娠结局的影响尚未不能确定。
[Abstract]:Objective: to measure the angle of mediastinal endometrium with 3-dimentional transvaginal ultrasound (3DTVU), and to investigate the relationship between the angle of endometrium and mediastinal remnant after mediastinectomy, and the relationship between the angle of endometrium and the pregnancy outcome after operation. Methods: 72 women with abortion and infertility underwent three-dimensional multi-planar ultrasound imaging. All patients were treated with transcervical resection of septum TCRSs under laparoscopic surveillance. The shape of uterus was observed on the coronal section of 3DTVU. The depth of notch at the bottom of uterus, the length of mediastinum and the angle between two sides of endometrium were measured. According to preoperative 3DTVU measurement of bilateral endometrial angle, the small angle group (< 90 o) and the large angle group (鈮
