应用经阴道三维超声诊断子宫畸形的价值研究

The Value of Three-dimensional Transvaginal Ultrasound in Diagnosing Congenital Uterine Anomalies

目的:探讨应用经阴道三维超声在诊断子宫畸形方面的价值。方法:对怀疑子宫畸形的126例患者进行经阴道二维、三维超声检查,并与宫腔镜、腹腔镜检查结果进行对比。结果:三维超声检查诊断准确率97.61%(123/126),其中不全纵隔子宫31例,完全性纵隔子宫13例,双子宫4例,双角子宫4例,单角子宫22例(其中17例合并残角子宫),弓型子宫32例,正常子宫20例,误诊3例(其中2例弓形子宫为假阳性,1例正常子宫伴子宫肌瘤被误诊为单角子宫合并残角子宫)。二维超声正确诊断99例,准确率为78.57%,明显低于三维超声的97.61%(P<0.01)。结论:经阴道三维超声成像诊断子宫畸形准确率高,具有重要的应用价值。

ObjectiveTo assess the value of three-dimensional transvaginal ultrasound in diagnosing congenital uterine anomalies.Method：Two-dimensional ultrasound and three-dimensional ultrasound were performed in 126 cases suspected uterine anomalies, and the results were verified with laparoscope and hysteroscopy.Result：Three dimensional ultrasound diagnostic accuracy rate of 97.61%（123/126）,including subseptate uterus in 31 cases,13 cases of complete septate uterus,4 cases of double uterus,4 cases of double uterus,unicornuate uterus in 22 cases（including 17 cases with rudimentary uterine horn）,32 cases of arch type uterus,20 cases of normal uterus,3 misdiagnosed cases（including 2 cases of arcuate uterus were false positive,1 case of normal uterus with uterine myoma misdiagnosed as single horn of uterus and rudimentary uterine horn）.Two dimensional ultrasound correctly diagnosed 99 cases,the accuracy rate was 78.57%,significantly lower than 97.61% of the dimensional ultrasound（P〈0.01）.Conclusion： Three-dimensional ultrasound has high diagnostic accuracy and great value in diagnosing congenital uterine anomalies.
