Spontaneous conception outcome in infertile women after four-dimensional hysterosalpingo-contrast-sonography.

BACKGROUND: Four-dimensional hysterosalpingo-contrast sonography (4D-HyCoSy) is the preferred way for evaluating fallopian tubal patency and it associated with higher rate of spontaneous conception. However, Few studies have evaluated the influencing factors of spontaneous conception in 4D-HyCoSy and suggested ways to choose treatment options after 4D-HyCoSy. The study was to evaluate the correlation between spontaneous conception outcome and the patients' clinical characteristics as well as tubal patency in infertile women to provide reference on ways to manage the patient after 4D-HyCoSy. METHODS: This was a retrospective study and analysis of two hundred and eighty three (283) infertile patients who underwent a 4D-HyCoSy between December 2014 and October 2017 in our center. Eligible patients were those whose partners semen parameters were normal when based on World Health Organization (WHO) criteria, and had spontaneous conception without clinical interventions after 4D-HyCoSy. RESULT(S): One hundred and sixteen patients (40.9%) conceived spontaneously and the mean conception time was (8.8 ± 0.3) months. Within a year after 4D-HyCoSy, the spontaneous conception rate was highest in type VI(62.5%), followed by type IV (46.2%), type III (44.4%), type V (39.4%), type II (33.9%) and type I (14.8%). With Cox regression analysis, two factors associated with spontaneous conception outcome appeared to increase spontaneous conception rate: patients with type IV or type VI tubes and duration of infertility less than 2 years. The age, type of infertility, multiparas, history of pelvic surgery, history of uterine cavity operation, uterine fibromyomata and polycystic ovary were unrelated to spontaneous conception outcome after 4D-HyCoSy. CONCLUSION(S): This study showed that some infertile women could succeed in spontaneous conception after 4D-HyCoSy. Hence, We recommend the usage of 4D-HyCoSy as first line for tubal patency test and infertile patients should be advised to accept 4D-HyCoSy examination as soon as possible. Expectant treatment of about 8-9 months is reported to be feasible for infertile women whose 4D-HyCoSy findings showed one tube patency or poor patency. Alternatively, an immediate clinical intervention is recommended for those with bilateral obstructed tubes .

The Influencing Factors of Venous Intravasation During Transvaginal Four-dimensional Hysterosalpingo-contrast Sonography With SonoVue.

Transvaginal 4-D hysterosalpingo-contrast sonography with SonoVue (TV 4-D HyCoSy) is the preferred imaging method for evaluating tubal patency. However, venous intravasation in 4-D HyCoSy may affect the diagnosis of tubal patency. The objective of this study was to analyze influencing factors of venous intravasation during TV 4-D HyCoSy. This study included 643 infertile patients who underwent TV 4-D HyCoSy. We analyzed the relationship between the incidence of venous intravasation and patients' basic clinical data, endometrial thickness, inspection timing (clean day of menstruation) and tubal patency. A total of 169 (26.28%) patients exhibited intravasation during TV 4-D HyCoSy. The following are risk factors for venous intravation: secondary infertility, type C + C, type B + C and type B + B in bilateral fallopian tubal patency grouping; endometrial thickness ≤5.45 mm; and taking TV 4-D HyCoSy after menstruation ≤6 d. Infertility duration, intrauterine lesions, a history of pelvic inflammatory disease and a history of pelvic surgery were uncorrelated with venous intravasation. To reduce the incidence of venous intravasation, TV 4-D HyCoSy should be performed 7-10 d after menstruation or when endometrial thickness is thicker than 5.45 mm.

Intravasation Affects the Diagnostic Image Quality of Transvaginal 4-Dimensional Hysterosalpingo-Contrast Sonography With SonoVue.

OBJECTIVES: We aim to retrospectively analyze the diagnostic image quality of transvaginal 4-dimensional hysterosalpingo-contrast sonography from infertile patients and determine the significant influencing factors. METHODS: A total of 445 patients visiting infertility clinics were included in the study, of which 167 were primary infertile and 278 were secondary infertile. The factors were recorded, including age; examination time; infertility type; history of pelvic inflammatory disease, pelvic surgery, intrauterine surgery, and ectopic pregnancy; endometrial thickness; uterine position; ovarian position; 2-dimensional image quality; intravasation quantity, position, and time; balloon volume; and the dosage of contrast agent or the sterile saline solution. All the factors were compared among different diagnostic image quality groups. The method of rank logistic regression analysis was adopted to analyze the risk factors affecting the diagnostic image quality. RESULTS: Among the 445 infertile patients, 124 (27.9%) patients had intravasation occur during transvaginal 4-dimensional hysterosalpingo-contrast sonography. The diagnostic image quality between the 2 sonographers was consistent (Cronbach's alpha, 0.993). Different intravasation quantities, positions, and times; increased of balloon volume; and history of pelvic surgery were substantial risk factors for the diagnostic image quality. The diagnostic image quality diminished with the increase of intravasation. In the patient with cornual intravasation, the diagnostic image quality was substantially worse than that with non-cornual intravasation. Moreover, early onset of intravasation seriously affected the diagnostic image quality. CONCLUSIONS: In conclusion, intravasation affected the diagnostic image quality, especially early cornual massive intravasation.

The Value of Percutaneous Shoulder Puncture with Contrast-enhanced Ultrasound in Differentiation of Rotator Cuff Tear Subtypes: A Preliminary Prospective Study.

Imaging tests perform relatively well in the detection of rotator cuff tears (RCTs), exhibiting high sensitivity and specificity, mainly among larger full-thickness tears (tear width >1 cm). However, these tests are relatively less accurate in the detection of small full-thickness tears and partial-thickness tears. The purpose of this study was to determine the feasibility of percutaneous ultrasound-guided tendon lesionography (PUTL) using the SonoVue and the value of percutaneous shoulder puncture via contrast-enhanced ultrasound (CEUS)-a combination of percutaneous ultrasound-guided subacromial bursography (PUSB) and PUTL-in the detection of RCT subtypes. Conventional ultrasound (US), CEUS and magnetic resonance imaging (MRI) were performed and prospectively evaluated in 97 patients who had undergone arthroscopy because of suspected RCTs. The rates of detection of the various subtypes of RCTs using CEUS, PUSB, PUTL, US and MRI were evaluated. The RCT subtype detection rate via CEUS was significantly higher than the rates via US and MRI (96.9%, 74.2% and 76.3%, respectively), as were the detection rates for small full-thickness tears combined with partial-thickness tears (98.2%, 60.0% and 61.8%, respectively). The detection rate with PUSB was significantly higher than those with US and MRI in assessing full-thickness tears combined with bursal-side partial-thickness tears (93.9%, 65.3% and 65.3%, respectively). The detection rate with PUTL was significantly higher than those with US and MRI in assessing the corresponding subtypes (100.0%, 69.2% and 76.9%, respectively). On the basis of our findings, we consider PUTL a tolerable and feasible procedure. Percutaneous shoulder puncture using CEUS can be an effective alternative method with better diagnostic performance than US and MRI for the detection of RCT subtypes.

Comparison of Assessment Methods for Fallopian Tubal Patency and Peritubal Adhesion Between Transvaginal 4-Dimensional Hysterosalpingo-Contrast Sonography and Laparoscopic Chromopertubation.

OBJECTIVES: The purpose of this study was to compare transvaginal 4-dimensional hysterosalpingo-contrast sonography with laparoscopic chromopertubation and evaluate the former's clinical value in assessing fallopian tubal patency and peritubal adhesion. METHODS: Fifty-six patients visiting infertility clinics were included in the study and underwent surgery by their own choice in 1 month. In total, 112 fallopian tubes were assessed. Twenty-five were primarily infertile, and the rest were secondarily infertile. Laparoscopic chromopertubation was taken as the reference standard. RESULTS: In a comparison of fallopian tubal patency between transvaginal hysterosalpingo-contrast sonography and laparoscopic chromopertubation, the sensitivity, specify, positive predictive value, and negative predictive value of hysterosalpingo-contrast sonography for diagnosing blocked fallopian tubes were 88.4%, 85.2%, 90.5%, and 82.1% respectively. In a comparison of spray at the fimbrial end between the no-peritubal adhesion and peritubal adhesion groups, the spray score at the fimbrial end in the no-peritubal adhesion group was significantly lower than that in the peritubal adhesion group. In a comparison of periovarian diffusion between the no-peritubal adhesion and peritubal adhesion groups, the periovarian diffusion score in the no-peritubal adhesion group was significantly lower than that in the peritubal adhesion group. In a comparison of periovarian diffusion between the patent-tube and blocked groups confirmed by chromopertubation, the periovarian diffusion score in the patent group was significantly lower than that in the blocked group. CONCLUSIONS: Transvaginal hysterosalpingo-contrast sonography is a method with high sensitivity and specificity for screening fallopian tubal patency and peritubal adhesion.
