Clinical data, management strategies, and follow-up outcomes were extracted from institutional records. A follow-up phone survey was conducted to assess fertility and obstetric outcomes.Forty women with symptomatic uterine AVMs were identified. All presented with vaginal bleeding, the sole symptom in 35 cases (87.5%). Most (31/40, 77.5%) presented at the emergency department within 24 hours. Thirty-eight women (95%) required one UAE; no hysterectomies were performed. Twelve women (30%) experienced massive bleeding requiring transfusion. Of 35 women who responded to the fertility survey, 22 (62.8%) desired a future pregnancy. Of these, 20 (90.9%) achieved pregnancy, with 17 (85%) delivering at term. The median time to conception was under 6 weeks, and 65% conceived within 12 months. Ten women (50%) had multiple successful pregnancies; one had 5 consecutive pregnancies. Regarding post-UAE pregnancies, 4 women (23.5%) experienced abnormal placentation, but no AVM recurrences were reported.In this cohort, UAE for AVMs is highly effective and fertility-sparing, with most women conceiving and delivering successfully. Obstetric risks remain notable, underscoring the need for larger studies to confirm these findings and assess long-term risks.","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2026-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146158967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two observers performed five measurements per subject using both probes (5C1 and DAX). Intra- and inter-observer reliability were assessed using intraclass correlation coefficients (ICC). Agreement between probes and observers was evaluated using Spearman correlation and Bland-Altman analysis, stratified by BMI subgroup.The intra- and inter-observer reliability of UDFF measurements were excellent, with no relevant systematic bias between observers or probes. The 5C1 and DAX probes showed strong correlations (r = 0.92 and 0.93). In normal-weight subjects, differences between probes were minimal, with limits of agreement (LoA) of approximately ±2%. In subjects with BMI ≥ 25, the mean differences between probes were low (up to 2.6%), but the limits of agreement were wider (-8% to +13%), comparable to the inter-observer variability.UDFF measurements with both the 5C1 and DAX probes showed consistently high reliability across BMI categories. Although variability increased with a higher BMI and liver fat, no systematic bias was observed, and both probes performed comparably. These findings support their interchangeable use in clinical settings.

Each participant had one attempt to solve the same MSUS case and could seek assistance from other group members or learning resources. The video-recorded sessions were analyzed using both quantitative and qualitative methods. Performance was assessed using the validated Objective Structured Assessment of Ultrasound Skills (OSAUS) tool (1-5 points per item), and an outcome score was calculated based on the number of correct MSUS images (0-4). Participants' comfort and perception of discovery learning were evaluated using a 5-point Likert scale questionnaire.28 MSUS experts from 13 different countries completed the study. The mean OSAUS score (standard deviation) was 3.96 (0.5), and the mean outcome score was 1.89 (0.9). Using Pearson's correlation coefficient, we found a significant correlation between the OSAUS score and the outcome score (0.72, p < .001). The qualitative analysis revealed that the experts used actions associated with adaptive expertise and that social hierarchy persisted in the collaborative learning environment. Finally, we found high comfort with and acceptance of the discovery learning approach.Discovery learning may be an effective teaching strategy for future advanced MSUS courses, including international Teach-the-Teachers courses.

Ultrasound could be used here as a widely available method for screening, but it is said to have very high investigator dependence. The fact that ultrasound can be used safely for diagnostic purposes has already been demonstrated. The aim of this study was to evaluate the repeatability of a standardized examination for the diagnosis of aTOS.We recruited inpatients with high-grade suspected arterial thoracic outlet syndrome who were evaluated for invasive therapy at our TOS center. Routine diagnostics were performed according to clinic standards. In addition, 2 sonographers, one highly experienced and one less experienced, performed ultrasound diagnosis according to a standardized protocol. Image acquisition and interpretation were performed independently, and sonographers were mutually blinded. For analysis, the experienced sonographer served as a reference. Agreement between assessors was analyzed using concordance analysis.51 consecutive patients (67% female) aged 39.3±13.0 years were included within 11 months. The standardized ultrasound protocol could be performed in all patients. The prevalence of TOS was high (79.4%; CI: 71.4-87.3%) in our cohort. Ultrasound inter-rater agreement using the standardized protocol was very good at 0.820 (CI: 0.624-1.000).Ultrasound diagnosis of TOS using a standardized protocol can be performed effectively and shows a high agreement between 2 sonographers.","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":" ","pages":"68-74"},"PeriodicalIF":2.9,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143494504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
