RESUMO
PURPOSE: To describe the feasibility of our preliminary outpatient fallopian tube catheterization procedure under 3D vaginal ultrasound (US) guidance followed by highly selective hysterosalpingo-foam sonography (HyFoSy) in infertile women diagnosed with proximal tubal obstruction. MATERIALS AND METHODS: A prospective trial was conducted from October 2022 to December 2023. 3D vaginal US was used to establish the precise location of the tip of the selective salpingography catheter at the tubal ostium. A roadrunner was used to cannulate the occluded portion of the fallopian tube. After tubal cannulation, ExEm foam was injected under direct US guidance to confirm tubal recanalization and its passage through the fallopian tubes. RESULTS: During the study period, a total of 14 women with proximal tubal occlusion underwent this procedure. Tubal patency was obtained in 92.8%. No immediate and remote complications were observed. To date three (21.4%) of the patients conceived after tubal catheterization and one had a live birth. CONCLUSION: Outpatient fallopian tube catheterization under 3D vaginal US guidance followed by selective HyFoSy can be successfully implemented for the diagnosis and treatment of patients with proximal tubal occlusion. The 3D modality enables volume capture of the required acquisitioning and the subsequent post imaging analysis permitting further examination and study. Additional experience is needed to consolidate the feasibility of this innovative procedure and identify the patient subgroups that would benefit the most from this approach.
RESUMO
OBJECTIVES: Term oligohydramnios is linked to pregnancy complications. We previously presented the outcome of the low-risk population (no pregnancy complications) with term oligohydramnios. This study aims to address the high-risk group (Any maternal complication during pregnancy, such as gestational diabetes, pre-gestational diabetes, chronic hypertension, preeclampsia, anemia, asthma, obesity, and multi parity.). METHODS: This retrospective cohort study of 1,114 singleton term (≥37), oligohydramnios (AFI <50â¯mm) pregnancies from Shamir Medical Center between 2017 and 2021. Compering the low-risk to high-risk groups with subdivision by severity of oligohydramnios. RESULTS: A total of 211 subjects (19â¯%) were high-risk cases and 903 (81â¯%) low-risk cases. Comparing these two groups, subjects of the high-risk group were older (31.34 ± 5.85 vs. 29.51 vs. 4.96), had earlier gestational age at delivery 39.53 ± 1.18 vs. 40, had higher mean AFI (35 ± 12.7 vs. 33 ± 14.5), were subject to more labor inductions (81 vs. 69.7â¯%), and CS rate (19.9 vs. 12.4â¯%). Logistic regression revealed a need for more cesarean sections in the high-risk group. Additionally, more labor inductions and a higher risk of negative fetal outcomes. CONCLUSIONS: This study highlights the importance of considering pregnancy risk factors when we are approaching oligohydramnios in high-risk pregnancies.
RESUMO
PURPOSE: The eccentric implantation of pregnancies in the upper lateral aspect of the uterine cavity is poorly defined clinically. The aim of the current study was to investigate whether differentiating between uterine anomalies that can lead to cavitary distortion has implications for the management of these pregnancies. METHODS: Eight cases of first-trimester eccentric pregnancy implantation within the endometrial cavity (study group) were retrospectively identified. For each woman in the study group, 10 women identified as having a first-trimester concentric pregnancy implantation during the first-trimester US examination were retrieved from our database (control group). After delivery or pregnancy demise, the presence of uterine anomalies was assessed by a 3D-US examination in all patients. RESULTS: In the study group patients, an increased incidence of uterine anomalies (50.0% vs. 8.8%, p = 0.007) was found, compared to the controls. In the study group, the eccentric location persisted in half of the pregnancies (n = 4; 50%), whereas the other half migrated to a more centric location within the endometrial cavity (n = 4; 50%). The follow-up examination showed that all the early pregnancy demises occurred in cases where the pregnancy persisted at the eccentric location. Uterine malformations were also detected in all these cases. CONCLUSION: The data point to a significantly higher incidence of uterine anomalies in patients diagnosed with eccentric pregnancy implantation within the endometrial cavity. These results advocate for the value of differentiating between eccentric pregnancies in non-anomalous versus anomalous uteri.
RESUMO
OBJECTIVE: Advances in ultrasound and molecular genetics have changed the field of late termination of pregnancy (LTOP), sparking ethical debates worldwide. In 2007, Israel updated its LTOP policies, requiring a 30% or higher probability of severe handicap for approval of LTOP after 24 weeks' gestation. PURPOSE: In this retrospective study, we compared LTOP indications and approval rates before (Group 1: 1998-2007) and after (Group 2: 2008-2021) this policy change. METHODS: Shamir medical records from January 1, 1998 to December 31, 2021 were examined and yielded 4047 abortions, of which 248 were identified as LTOP preformed after 24 weeks' gestation. These cases were then categorized into two groups. Data including maternal age, obstetric history, indications for abortion, diagnosis, week of termination, and genetic/sonographic findings were analyzed. The approval rates and indications pre- and post-policy change were compared. RESULTS: Group 1 (LTOP 1998-2007) comprised 95 cases (10.6%), and Group 2 (LTOP 2008-2021) was composed of 153 cases (4.9%). Fetal structural anomalies remained the dominant indication for both groups (67.4 and 65.3%, respectively), with a slight increase in confirmed genetic anomalies from 26.3% (Group 1) to 28% (Group 2). CONCLUSION: Our findings indicate a decrees in the proportion per year from 10.6 to 4.9% LTOP. Technological advances in genetic evaluation and sonography may have contributed to the early increased detection and decrees in cases reaching LTOP. These results highlight the importance of ongoing ethical reviews and adherence to strict protocols for early detection and termination before 24 weeks' gestation.
RESUMO
OBJECTIVE: Clinical-sonographic scoring systems combining clinical features and ultrasound imaging markers have been proposed for the screening of placenta accreta spectrum, but their usefulness in different settings remains limited. This study aimed to assess and compare different clinical-sonographic score systems applied from mid-pregnancy for the prenatal evaluation of patients at risk of placenta accreta spectrum at birth. DATA SOURCES: PubMed/MEDLINE, Google Scholar, and Embase were searched between October 1982 and October 2022 to identify eligible studies. STUDY ELIGIBILITY CRITERIA: Observational studies providing data on the use of a combined clinical-ultrasound score system applied from mid-pregnancy for the prenatal evaluation of placenta accreta spectrum were included. METHODS: Study characteristics were evaluated by 2 independent reviewers using a predesigned protocol registered on PROSPERO (CRD42022332486). Heterogeneity among studies was analyzed with Cochran's Q-test and I2 statistics. Statistical heterogeneity was quantified by estimating the variance between the studies using I2 statistics. The area under the receiver operating characteristic curve of each score and their summary receiver operating characteristic curves were calculated with sensitivity and specificity, and the integrated score of the summaries of the receiver operating characteristic curves of all sonographic markers was calculated. Forest plots were used to develop the meta-analysis of each sonographic marker and for the integrated sonographic score. RESULTS: Of 1028 articles reviewed, 12 cohorts and 2 case-control studies including 1630 patients screened for placenta accreta spectrum by clinical-ultrasound scores met the eligibility criteria. A diagnosis of placenta accreta spectrum was reported in 602 (36.9%) cases, for which 547 (90.9%) intraoperative findings and/or histopathologic data were described. A wide variation was observed among the studies in reported sensitivities and specificities and in thresholds used for the identification of patients with a high probability of placenta accreta spectrum at birth. The summaries of the areas under the curve of the individual sonographic scores ranged from 0.85 (the lowest) for subplacental hypervascularity to 0.91 for placental location in the lower uterine segment, myometrial thinning, and placental lacunae and 0.95 for the loss of clear zone. Only 4 studies included placental bulging in their sonographic score system, and therefore no meta-analysis for this score was performed. The integrated summary of the areas under the curve was 0.83 (95% confidence interval, 79-0.86). Forest plot analysis revealed integrated sensitivities and specificities of 0.68 (95% confidence interval, 0.53-0.80) and 0.88 (95% confidence interval, 0.68-0.96), respectively. CONCLUSION: Clinical-sonographic score systems can contribute to the prenatal screening of patients at risk of placenta accreta spectrum at birth. Although we included multiple sonographic studies conducted during the mid-pregnancy period, standardized evaluation should be performed not only with strict ultrasound criteria for the placental position, mid third trimester gestational age at examination, and sonographic markers associated with PAS. Numeric sensitivities, specificities, NPVs, PPV, LR-, and LR+ should be recorded prospectively to assess their accuracy in different set-ups and PTP should be verified at delivery. The variables recommended for most predictive screening are: loss of clear zone underneath the placental bed, placentation in the LUS, and placenta lacunae.
RESUMO
BACKGROUND: Termination of pregnancy is a difficult moral dilemma that provokes a discussion in the public, from an ethical, moral and religious point of view. This process is complex, especially when it comes to a fetus at a viability age (late abortion, after week 24), which requires the approval of a regional supreme committee. OBJECTIVES: To examine the various causes of abortion both before and after the fetal viability age (24 weeks of gestation and beyond) in a singleton pregnancy, as well as to examine the sequence of events that led to a late abortion. METHODS: In this cohort study, 4,057 patients who had abortions due to fetal abnormalities in the Shamir Medical Center during the years 1998-2021, were divided according to the abortion indications. Of these, 3539 (91.28%) had early abortion (24 weeks and below) and 338 (8.72%) had late abortions (24 week and later). RESULTS: In general, the leading reasons for abortions are chromosomal and genetic (1862 [46%]) as well as anatomical indication (1868 [46%]). It was found that the leading indication for early abortion is the chromosomal or genetic abnormalities (1702 [48.1%]), while the leading indication for late abortion is anatomical defects (204 [60.4%]) (p=0.000). In late abortion, the leading anatomical cause is heart defects (62 [30.54%]) followed by central nervous system defects (56 [26.6%]), and the leading chromosomal cause is trisomy 21 (Down syndrome) (23 [22.33%]). When examining the sequence of events that led to late abortion, the leading reason is abnormal findings that required further studies (125 [37%]). CONCLUSIONS: There is great importance in trying to reduce late pregnancy abortion by understanding the sequence of events and the reasons that led to it. Changing the processes that need to be performed can be implemented by combining pathways: improving the technological means, using more accurate instrumentation and advanced molecular genetics. Furthermore, it is essential to raise the awareness of the pregnant women on screening tests, and conducting this as early as possible. Additionally, it is important to raise the skill of the operators. We believe that incorporating all those actions will lead to earlier diagnosis and to a decrease in late abortions, a promising message both from the point of view of the women and the medical staff, due to the difficulty in carrying out late pregnancy terminations.

SUMMARY Ovarian adrenal rest tumors (OARTs) are very rare. We describe a case of a young woman with uncontrolled classical congenital adrenal hyperplasia (CCAH), presenting with bilateral OARTs, successfully treated with steroid replacement. A 20-year-old woman, known to have 21OH-CCAH, presented with severe abdominal pain, vomiting, diarrhea, and fever. As a result of poor compliance, 6 months before her admission hirsutism worsened and amenorrhea, hyperpigmentation, and weakness developed. ACTH levels were 278 < pmol/L and 17OHP 91.3 nmol/L. She was admitted for parenteral antibiotics and high-dose hydrocortisone treatment. CT revealed bilateral juxta-ovarian masses (6.2 x 3.6 x 7.4 cm left and 5 x 2.2 x 3.2 cm right) that on MRI were iso-intense in T1 and hypointense in T2, with early enhancement and rapid washout. One week of high-dose hydrocortisone resulted in significant clinical and laboratory improvement and the patient was discharged with 2 mg dexamethasone/day. One month later US revealed shrinkage of the masses and dexamethasone dose was decreased. At three months from discharge, she has resumed regular menses, and a repeated MRI revealed the para-ovarian masses have shrunk. One year after the diagnosis, the para-ovarian masses have shrunk more to 2.8 x 1.9 x 4.3 on the left and 2.1 x 0.9 x 1.2 on the right with less contrast enhancement in comparison to previous test possibly due to fibrotic changes of the tissue. OARTs are rare tumors with a poorly known natural history, and surgery has been the first option in the few reported cases. We demonstrate that medical treatment is a good alternative, leading to significant tumor shrinkage over a short period.
