Factors Associated with a Post-Procedure Spontaneous Pregnancy after a Hysterosapingo-Foam-Sonography (HyFoSy): Results from a Multicenter Observational Study.

BACKGROUND: Tubal patency testing constitutes an essential part of infertility work-up. Hysterosalpingo-foam-sonography (HyFoSy) is currently one of the best tests for assessing tubal patency. The objective of our study was to evaluate the post-procedure rate of spontaneous pregnancy among infertile women submitted for an HyFoSy exam with ExEm® foam and the factors associated with this. METHODS: Multicenter, prospective, observational study performed at six Spanish centers for gynecologic sonography and human reproduction. From December 2015 to June 2021, 799 infertile women underwent HyFoSy registration consecutively. The patients' information was collected from their medical records. Multivariable regression analyses were performed, controlling for age, etiology, and time of sterility. The main outcome was to measure post-procedure spontaneous pregnancy rates and the factors associated with the achievement of pregnancy. RESULTS: 201 (26.5%) women got spontaneous conception (SC group), whereas 557 (73.5%) women did not get pregnant (non-spontaneous conception group, NSC). The median time for reaching SC after HyFoSy was 4 months (CI 95% 3.1-4.9), 18.9% of them occurring the same month of the procedure. Couples with less than 18 months of infertility were 93% more likely to get pregnant after HyFoSy (OR 1.93, 95% CI 1.34-2.81; p < 0.001); SC were two times more frequent in women under 35 years with unexplained infertility (OR 2.22, 95% CI 1.07-4.65; P0.033). CONCLUSION: After HyFoSy, one in four patients got pregnant within the next twelve months. Couples with shorter infertility time, unexplained infertility, and women under 35 years are more likely to achieve SC after HyFoSy.

Fetal intracranial hemorrhage. Prenatal diagnosis and postnatal outcomes.

OBJECTIVE: To present our experience with 14 cases of fetal intracranial hemorrhage (ICH). METHODS: Cases of fetal ICH detected in our institution between 2005 and 2016 by ultrasonography. Maternal characteristics, ultrasound and MRI findings, and postnatal outcome were noted. RESULTS: Twelve cases (86.7%) were identified during a third trimester routine scan at a median gestational age of 30.6 weeks. The ICH was classified as Grade 2 in two cases, Grade 3 in three cases, and Grade 4 in nine cases. Nine cases were bilateral and five were unilateral (four left/one right). The 11 MRI available confirmed grade and location and, in six cases (54.5%), added new findings. There were six terminations of pregnancy, one intrauterine fetal death and seven babies born alive. These were followed up for 28 months (range 3-96). Some grade of neurologic impairment was observed in five children (71.4%, one Grade 3/four Grade 4), mainly mild to moderate motor sequelae. CONCLUSION: Diagnosis of fetal ICH is amenable to antenatal US. Most of the cases identified are of high grade and usually detected during the third trimester. MRI is a valuable complementary tool in evaluating ICH. Conversely to that previously reported, postnatal survival is high but it entails the risk of adverse neurologic outcome in most neonates.

Fetal pericallosal lipomas - Clues to diagnosis in the second trimester.

INTRODUCTION: Pericallosal lipomas (PCL) are congenital soft masses of adipose cells encapsulated by a thin layer of fibrous tissue, appearing adjacent to the corpus callosum (CC). The lipomas are usually diagnosed prenatally during the third trimester. The purpose of this study was to identify 2nd trimester ultrasound findings that may hint to a later diagnosis of PCL and to evaluate their MRI evolution. METHODS: A multicenter study of fetuses diagnosed during the 3rd trimester with a PCL in 7 fetal ultrasound units between 2001 and 2017. We reevaluated the ultrasound and MRI images starting from the referral examination and until the time of diagnosis, searching for clues that could have prompted an earlier diagnosis. Parents were contacted at the end of the study period to obtain information regarding development and neurological examination. RESULTS: Fifteen patients with PCL were diagnosed during the study period; fourteen had second trimester scans. A 2nd trimester diagnosis was established in only 2 (13.3%). Anomalies of the CC were evident in 8/14 patients during the 2nd trimester scan and included: short length (n = 4), increased thickness (n = 1), complete agenesis (n = 2) and partial agenesis (n = 1). Third trimester ultrasound scans were considered diagnostic of PCL in all 12 remaining cases, in eight it was considered an isolated finding. Postnatal neurological evaluation in the isolated cases revealed normal development in all children. One child was diagnosed with attention deficit disorder. CONCLUSIONS: Non visualization of a PCL during the 2nd trimester is common, and should not be considered a diagnostic error. An underlying PCL should be included in the differential diagnosis of CC anomalies during this time period, necessitating further follow up into the 3rd trimester.

Brainstem-vermis and brainstem-tentorium angles: 3D ultrasound study of the intra- and inter-observer agreement.

OBJECTIVE: The brainstem-vermis angle (BVA) and the brainstem-tentorium angle (BTA) have been proposed to quantify vermian and tentorial alterations associated to fetal posterior fossa malformations. Our objective is to evaluate the intra- and inter-observer agreement for the measurement of these angles during the prenatal ultrasound scan. METHODS: Fifteen 3 D sets from fetuses with posterior fossa pathology were processed by multiplanar navigation. Four experts in prenatal ultrasound measured the BVA and the BTA on a mid-sagittal view of the fetal brain, following the criteria described by Volpe. Observer 1 did also repeated measurements following both the criteria by Volpe and Ghi. The intraclass correlation coefficient (ICC) was used to test consistency and absolute agreement for intra- and inter-observer measurements. The concordance is poor when ICC <0.40 and excellent when ICC >0.75. RESULTS: Consistency ICC for measurements between the 4 observers was 0.74 (95% CI: 0.54-0.89) for the BVA and 0.55 (95% CI: 0.29-0.78) for the BTA. Absolute agreement ICC was 0.67 (BVA) and 0.45 (BTA). The intra-observer study showed a significantly greater angle with the criteria by Ghi (mean 52.1°, 95% CI: 49.5-54.8) than with the criteria by Volpe (mean 37.4°, 95% CI: 33.1-41.6). CONCLUSIONS: A more precise methodology for the measurement of these angles should be described.

The Thessaloniki ESHRE/ESGE consensus on diagnosis of female genital anomalies.

What is the recommended diagnostic work-up of female genital anomalies according to the European Society of Human Reproduction and Embryology (ESHRE)/European Society for Gynaecological Endoscopy (ESGE) system? The ESHRE/ESGE consensus for the diagnosis of female genital anomalies is presented. Accurate diagnosis of congenital anomalies still remains a clinical challenge due to the drawbacks of the previous classification systems and the non-systematic use of diagnostic methods with varying accuracy, with some of them quite inaccurate. Currently, a wide range of non-invasive diagnostic procedures are available, enriching the opportunity to accurately detect the anatomical status of the female genital tract, as well as a new objective and comprehensive classification system with well-described classes and sub-classes. The ESHRE/ESGE Congenital Uterine Anomalies (CONUTA) Working Group established an initiative with the goal of developing a consensus for the diagnosis of female genital anomalies. The CONUTA working group and imaging experts in the field have been appointed to run the project. The consensus is developed based on (1) evaluation of the currently available diagnostic methods and, more specifically, of their characteristics with the use of the experts panel consensus method and of their diagnostic accuracy performing a systematic review of evidence and (2) consensus for (a) the definition of where and how to measure uterine wall thickness and (b) the recommendations for the diagnostic work-up of female genital anomalies, based on the results of the previous evaluation procedure, with the use of the experts panel consensus method. Uterine wall thickness is defined as the distance between interostial line and external uterine profile at the midcoronal plane of the uterus; alternatively, if a coronal plane is not available, the mean anterior and posterior uterine wall thickness at the longitudinal plane could be used. Gynaecological examination and two-dimensional ultrasound (2D US) are recommended for the evaluation of asymptomatic women. Three-dimensional ultrasound (3D US) is recommended for the diagnosis of female genital anomalies in "symptomatic" patients belonging to high-risk groups for the presence of a female genital anomaly and in any asymptomatic woman suspected to have an anomaly from routine avaluation. Magnetic resonance imaging (MRI) and endoscopic evaluation are recommended for the sub-group of patients with suspected complex anomalies or in diagnostic dilemmas. Adolescents with symptoms suggestive for the presence of a female genital anomaly should be thoroughly evaluated with 2D US, 3D US, MRI and endoscopy. The various diagnostic methods should be used in a proper way and evaluated by experts to avoid mis-, over- and underdiagnosis. The role of a combined ultrasound examination and outpatient hysteroscopy should be prospectively evaluated. It is a challenge for further research, based on diagnosis, to objectively evaluate the clinical consequences related to various degrees of uterine deformity.

The Thessaloniki ESHRE/ESGE consensus on diagnosis of female genital anomalies.

STUDY QUESTION: What is the recommended diagnostic work-up of female genital anomalies according to the European Society of Human Reproduction and Embryology (ESHRE)/European Society for Gynaecological Endoscopy (ESGE) system? SUMMARY ANSWER: The ESHRE/ESGE consensus for the diagnosis of female genital anomalies is presented. WHAT IS KNOWN ALREADY: Accurate diagnosis of congenital anomalies still remains a clinical challenge because of the drawbacks of the previous classification systems and the non-systematic use of diagnostic methods with varying accuracy, some of them quite inaccurate. Currently, a wide range of non-invasive diagnostic procedures are available enriching the opportunity to accurately detect the anatomical status of the female genital tract, as well as a new objective and comprehensive classification system with well-described classes and sub-classes. STUDY DESIGN, SIZE, DURATION: The ESHRE/ESGE CONgenital UTerine Anomalies (CONUTA) Working Group established an initiative with the goal of developing a consensus for the diagnosis of female genital anomalies. The CONUTA working group and imaging experts in the field have been appointed to run the project. PARTICIPANTS/MATERIALS, SETTING, METHODS: The consensus is developed based on: (i) evaluation of the currently available diagnostic methods and, more specifically, of their characteristics with the use of the experts panel consensus method and of their diagnostic accuracy by performing a systematic review of evidence and (ii) consensus for the definition of where and how to measure uterine wall thickness and the recommendations for the diagnostic work-up of female genital anomalies, based on the results of the previous evaluation procedure, with the use of the experts panel consensus method. MAIN RESULTS AND THE ROLE OF CHANCE: Uterine wall thickness is defined as the distance between the interostial line and external uterine profile at the midcoronal plane of the uterus; alternatively, if a coronal plane is not available, the mean anterior and posterior uterine wall thickness at the longitudinal plane could be used. Gynecological examination and two-dimensional ultrasound (2D US) are recommended for the evaluation of asymptomatic women. Three-dimensional (3D) US is recommended for the diagnosis of female genital anomalies in 'symptomatic' patients belonging to high risk groups for the presence of a female genital anomaly and in any asymptomatic woman suspected to have an anomaly from routine evaluation. Magnetic resonance imaging (MRI) and endoscopic evaluation are recommended for the subgroup of patients with suspected complex anomalies or in diagnostic dilemmas. Adolescents with symptoms suggestive for the presence of a female genital anomaly should be thoroughly evaluated with 2D US, 3D US, MRI and endoscopically. LIMITATIONS, REASONS FOR CAUTION: The various diagnostic methods should always be used in the proper way and evaluated by experts to avoid mis-, over- and underdiagnosis. WIDER IMPLICATIONS OF THE FINDINGS: The role of a combined US examination and outpatient hysteroscopy should be prospectively evaluated. It is a challenge for further research, based on diagnosis, to objectively evaluate the clinical consequences related to various degrees of uterine deformity. STUDY FUNDING/COMPETING INTERESTS: None.

Intracranial translucency at 11-13 weeks of gestation: prospective evaluation and reproducibility of measurements.

OBJECTIVE: This paper aimed to determine the feasibility of identification and measurement reproducibility of intracranial translucency (IT) in our population. METHODS: This is a prospective study in which five accredited operators attempted to identify and measure the IT during first-trimester sonographic screening for aneuploidy in 990 fetuses. The presence or absence of spina bifida was determined at the time of the second-trimester scan or after birth. Measurement reproducibility was assessed through intraclass correlation coefficient (ICC) on a subgroup of 150 fetuses. RESULTS: Identification and measurement of the IT were possible in 961 (97%) cases. The mean IT anteroposterior diameter was 1.8 mm (SD ± 0.37; range 0.8-3.1), and the size increased linearly with advancing gestation (IT = 0.74 + 0.02 × crown-rump length; r(2) = 0.15, p < 0.0001). The only fetus with spina bifida in this series presented with absent IT. Intra-observer and inter-observer ICCs were 0.79 and 0.75, respectively (95% confidence intervals 0.72-0.84 and 0.67-0.81, respectively; both p < 0.001). CONCLUSIONS: The IT increases linearly with increasing crown-rump length and seems to be of value in the first-trimester detection of spina bifida. It is easy to identify and measure and shows excellent intra-observer and inter-observer reproducibility measurements.
