Clinical evaluation of tubal patency by transvaginal four-dimensional hysterosalpingo-contrast sonography / 中华医学超声杂志（电子版）

ABSTRACT

Objective To explore the clinical value of transvaginal four-dimensional hysterosalpingo-contrast sonography (TVS 4D-HyCoSy)in evaluation of the patency of fallopian tubes. Methods Totally 53 patients underwent SonoVue TVS4D-HyCoSy to observe the tubal patency. Results Among the 106 tubes in 53 patients, TVS 4D-HyCoSy showed 47 unobstructed tubes, 23 obstructed tubes, and 36 partially passable tubes. In unobstructed cases, the fallopian tubes were smooth and regular in morphology, and contrast agents flowed into and dispersed over pelvic cavity rapidly and evenly. In the cases of partially passable tube, fallopian tubes were discontinuous and irregular in morphology, and contrast agents lfowed into and dispersed over pelvic cavity slowly and unevenly. In obstructed cases, there were no or little contrast agents into the fallopian tubes. Compared with the results of laparoscopy, the diagnostic accuracy of TVS 4D-HyCoSy was 94.4%(17/18). Conclusions TVS 4D-HyCoSy is a useful tool in demonstrating the morphological features of fallopian tube, diagnosing intrauterinc adhesion and lesion and assessing the tubal patency.
