Detection of Congenital Uterine Malformation by Using Transvaginal Three-dimensional Ultrasound

This study assessed the clinical application of transvaginal three-dimensional ultrasound （3D TVUS） in the diagnosis of congenital uterine malformation. A retrospective study was performed on 62 patients with congenital uterine malformation confirmed hysteroscopically and/or laparoscopically. The patients were subjected to transvaginal two-dimensional ultrasound （2D TVUS） and 3D TVUS. The accuracy rate was compared between the two methods. The accuracy rate of 3D TVUS was （98.38%, 61/62）, higher than that of 2D TVUS （80.65%, 50/62）. 3D TVUS coronal plane imaging could demon- strate the internal shape of the endometrial cavity and the external contour of the uterine fundus. It al- lowed accurate measurement on the coronary plane, and could three-dimensionally show the image of cervical tube, thereby providing information for the diagnosis of some complex uterine malformation. 3D TVUS imaging can obtain comprehensive information of the uterus malformation, and it is superior to 2D TVUS for the diagnosis of congenital uterine malformations, especially complex uterine anomaly.

经阴道三维超声对剖宫产瘢痕部位妊娠的早期预测价值

目的探讨经阴道三维超声对剖宫产瘢痕部位妊娠的早期预测价值。方法回顾性分析2016年4月-2018年4月佛山市妇幼保健院临床诊断为剖宫产瘢痕部位妊娠的患者142例。术前均行经阴道三维超声及经阴道二维超声检查。比较2种检查方式的诊断符合率,分析对切口孕囊型、包块型、部分切口及部分宫腔孕囊型剖宫产瘢痕部位妊娠的诊断结果,并计算2种检查方法的敏感性及特异性。结果52例患者确诊为剖宫产瘢痕部位妊娠,其中切口孕囊型22例,包块型13例,部分切口及部分宫腔孕囊型17例。经阴道二维超声阳性诊断符合率为55.74%(34/61),经阴道三维超声检查阳性诊断符合率为85.45%(47/55),2种检查方法比较,差异有统计学意义(P<0.05),经阴道三维超声检查阳性诊断符合率高于经阴道二维超声检查。2种检查方法检查切口孕囊型剖宫产瘢痕部位妊娠结果比较,差异无统计学意义(P>0.05)。经阴道三维超声检查对包块型、部分切口及部分宫腔孕囊型剖宫产瘢痕部位妊娠的确诊率高于经阴道二维超声检查(P<0.05)。经阴道三维超声检查诊断剖宫产瘢痕部位妊娠的敏感性、特异性、ROC曲线下面积均高于经阴道二维超声检查。结论经阴道三维超声应用于剖宫产瘢痕部位妊娠的早期诊断,具有较高的敏感性及特异性,阳性符合率高,为提高临床诊断准确性提供客观依据。
