Application of transvaginal real-time three-dimensional hysterosalpingo-contrast sonography in infertility

Abstract

Objective To investigate the clinical application of transvaginal real-time three-dimensional hysterosalpingo-contrast sonography (TVS RT-3D-HyCoSy) in infertility. Methods In 202 women with infertility, 385 fallopian tubes were examined by transvaginal hysterosalpingography under real-time three-dimensional (4D) mode of ultrasound, and the development of the liquid in uterine cavity and fallopian tube was observed continuously. Normal saline was injected into the uterine cavity before pulling out the double lumen catheter to observe uterine cavity lesions by two-dimensional ultrasound (2D); and the shape of the uterine cavity was evaluated by three-dimensional volumetric imaging (3D) after the catheter was pulled out. Results Among the 385 fallopian tubes in the 202 women, 298 fallopian tubes were diagnosed with patency by contrast-enhanced ultrasonography, 32 incompletely obstructed, and 55 completely obstructed. There were 3 cases of endometrial polyp, 4 cases of intrauterine adhesion, 4 cases of abnormal uterine cavity morphology, and 26 cases of myometrium countercurrent and/or venous countercurrent. Conclusion Transvaginal real-time three-dimensional hysterosalpingo-contrast sonography can observe the development of the liquid in uterine cavity and fallopian tube in real time, and accurately judge the patency of fallopian tube. Three-dimensional ultrasound and two-dimensional ultrasound supplementary observation have important values in judging uterine cavity morphology and uterine cavity pathological changes.
