Transvaginal hysterosalpingo-contrast sonography for the assessment of tubal patency with gray scale imaging and additional use of pulsed wave Doppler.

OBJECTIVE: To determine whether the additional use of pulsed wave (PW) Doppler can improve the tubal diagnosis reached with gray scale imaging in doubtful cases. DESIGN: The study is an open, uncontrolled clinical trial of women of childbearing age. SETTING: Clinical environment. PATIENTS: Seventeen female patients (23 to 37 years of age) with diagnosed sterility problems. INTERVENTIONS: The contrast agent SH U 454 was administered transcervically during transvaginal gray scale and PW Doppler sonography. MAIN OUTCOME MEASURES: Hysterosalpingo-contrast sonography by gray scale and by PW Doppler and follow-up chromolaparoscopy (n = 16) or hysterosalpingography (HSG, n = 1) were performed. The diagnostic efficacy of gray scale and PW Doppler were compared with each other and against a conventional control procedure (chromolaparoscopy or HSG). RESULTS: The gray scale findings were confirmed by PW Doppler in 5 cases on one side; confirmed by PW Doppler in 7 cases on both sides; corrected by PW Doppler in 4 cases on one side; and corrected by PW Doppler in 1 case on one side and confirmed on the other side by PW Doppler. In all 17 cases, the tubal findings after PW Doppler were confirmed by chromolaparoscopy or HSG. CONCLUSION: The additional use of PW Doppler in hysterosalpingo-contrast sonography is recommended as a supplement to gray scale imaging (1) in cases of suspected tubal occlusion and (2) in the event of intratubal flow demonstrable only over a short distance.

[Transvaginal contrast hysterosalpingo-sonography with the B-image procedure and color-coded duplex sonography for the assessment of fallopian tube patency].

Transvaginal hysterosalpingo-contrast-sonography (HYCOSY), a new method for the direct assessment of tubal patency by means of ultrasonography, was employed in 68 women with infertility problems. In 67 cases, the findings were compared with hysterosal-pinography or chromolaparoscopy, performed either subsequently while the patient was still under the anaesthetic or later. The contrast demonstration of the Fallopian tubes was performed with the B mode procedure in 54 cases (Group 1) and by means of colour-coded duplex sonography in 14 (Group 2). In Group 1, the findings agreed completely in 39 cases, partially in 14 and not at all in one. In Group 2, in which 13 of the 14 cases were compared, the findings were identical in 9 cases and partially in 4. From the point of view of image documentation, the more vivid demonstration of free tubal passage in colour Doppler sonography compared to the simple B mode appears to be an advantage. Further studies are needed to determine whether contrast-perfused but dislocated tubes can be detected more easily and quickly with colour Doppler than in B mode.

Transvaginal hysterosalpingo-contrast-sonography (Hy-Co-Sy) compared with conventional tubal diagnostics.

Transvaginal hysterosalpingo-contrast-sonography (Hy-Co-Sy) is described as a new method for direct imaging of the tubal passage in tubal diagnostics. During one period of anaesthesia, a transvaginal Hy-Co-Sy was followed by either hysterosalpingography or chromolaparoscopy in 42 patients with sterility disorders. The contrast-enhanced sonography of the tubes was performed in eight cases with sterile saline solution (group 1) and 34 cases with a specially developed ultrasound contrast medium (SH U 454, group 2). The findings obtained by transvaginal Hy-Co-Sy were compared with those of the conventional method. By both methods, there was complete agreement with respect to the same evaluation of tubal passage for both sides, partial agreement when firstly the tubes were assessed as unilaterally or bilaterally open--without precise localization of the side--depending on the appearance of fluid in the pouch of Douglas, or secondly, only one side, when compared, showed agreement. In group 1 complete agreement was found once, partial agreement five times and non-agreement twice, while in group 2 complete agreement was found 22 times (65%), partial agreement 11 times and non-agreement once.

[Transvaginal contrast hysterosonography. A new diagnostic procedure for the differentiation of intrauterine and myometrial findings].

In 30 patients with sterility problems, menstrual irregularities, and/or suspected tumor the uterine wall was evaluated by transvaginal hystero-contrast-sonography (CoSy). These findings were compared with those of hysterosalpingography (HSG) or chromo-laparoscopy which were done during the same anesthesia. In 6 patients there was no coincidence, and additional information of relevance could be achieved by the other procedure. One case of submucous and an other of intramural fibroid were exactly differentiated by the transvaginal CoSy. This was not possible by the HSG. In addition two large intramural fibroids were exactly localized by CoSy, where as this couldn't be demonstrated endoscopically. Two uteri arcuati have not been seen by CoSy, but were recognized by HSG. So we recommend the transvaginal CoSy of the uterus as a pretherapeutic procedure for the differentiation and localization of intracavital and myometrial findings. At least at moment it seems to be that the image of light uterine malformations could be better demonstrated by conventional diagnostic methods.
