The latter group was reassessed after 1-2 weeks and, if the abnormal presentation persisted, the parents were offered ECV or elective Cesarean section at 38-40 weeks' gestation.

In the remaining 74.5% of cases, ECV was not attempted because of any of the following reasons: ECV was declined; Cesarean section was planned for a reason other than abnormal presentation; ECV was planned for the subsequent 1-2 weeks but, in the meantime, there was spontaneous rotation to cephalic presentation; or there was spontaneous onset of labor or rupture of membranes before planned ECV. In 5513/6211 (88.8%) pregnancies with non-cephalic presentation at the 36-week scan, ECV was not attempted or was unsuccessful, and in 37.7% of these, there was subsequent spontaneous rotation to cephalic presentation. Among the 6211 pregnancies with non-cephalic presentation at the 36-week scan, the presentation at birth was cephalic in 43.8%; in 74.8%, this was due to spontaneous rotation, and in 25.2%, it was due to successful ECV.

We assessed the impact of fibroids and their characteristics, identified on ultrasound imaging at 11 + 0 to 13 + 6 weeks, on the risk of late miscarriage occurring at 11 + 0 to 21 + 6 weeks. Fibroid number, location and size were investigated, and adjusted odds ratios (aORs) with 95% CIs were calculated using multiple logistic regression and propensity score analysis via inverse probability of treatment weighting (IPTW) to minimize confounding. Singleton pregnancies without uterine fibroids comprised the control group. We further calculated the adjusted absolute risk (aAR) for the control group and the adjusted risk differences (aRD) for the study groups.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;In total, 31 355 singleton pregnancies were analyzed, of which 942 (3.0%) had uterine fibroids. Multiple logistic regression analysis showed that pregnancies with a single fibroid did not have higher odds for late miscarriage compared to those without fibroids (aOR, 1.2 (95% CI, 0.6-2.4)), but women with multiple fibroids did have higher odds of late miscarriage (aOR, 2.5 (95% CI, 1.0-6.2)). Similarly, multiple logistic regression analysis after IPTW did not find higher odds of late miscarriage in pregnancies with a single fibroid (aOR, 1.7 (95% CI, 0.9-3.0) and aRD, 0.7% (95% CI, -0.2 to 2.1%)) but revealed increased odds of late miscarriage in women with multiple fibroids (aOR, 2.9 (95% CI, 1.1-7.3) and aRD, 2.0% (95% CI, -0.6 to 9.7%)). Analysis of the location of single fibroids revealed that submucosal fibroids significantly increased the odds of late miscarriage by 4.7 times, while the presence of fibroids in other locations did not have a statistically significant association with late miscarriage. When we limited our study population to cases with submucosal and intramural fibroids, logistic regression showed no significant increase in the odds of miscarriage for a single fibroid (aOR, 1.8 (95% CI, 0.9-3.5) and aRD, 1.2% (95% CI, -0.1 to 3.1%)), but revealed significantly higher odds for multiple fibroids (aOR, 3.8 (95% CI, 1.4-10.6) and aRD, 5.1% (95% CI, 0.6-22.0%)) compared with controls. IPTW analysis found a 2.3-fold increase in the odds of late miscarriage for a single fibroid (aOR, 2.3 (95% CI, 1.2-4.2)) and an even larger increase in the odds of late miscarriage for multiple fibroids (aOR, 5.7 (95% CI, 2.2-15.1)).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;Uterine fibroids are associated with increased odds of late miscarriage, particularly when they are multiple and submucosal. © 2025 International Society of Ultrasound i","PeriodicalId":23454,"journal":{"name":"Ultrasound in Obstetrics & Gynecology","volume":"65 2","pages":"198-205"},"PeriodicalIF":6.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143081176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Women identified as being at high risk (≥ 1:100) for preterm PE by the FMF triple test were matched 1:1 with women identified as low risk (&lt; 1:100) for maternal age ± 3 years, maternal weight ± 5 kg and date of screening ± 14 days. Two-dimensional transthoracic echocardiography was performed at 12 + 0 to 15 + 6 weeks to evaluate maternal hemodynamic parameters (heart rate (HR), stroke volume (SV), cardiac output (CO) and systemic vascular resistance (SVR)). Maternal hemodynamic parameters were expressed as multiples of the median (MoM) values, determined by linear regression models to adjust for gestational age (GA) and MF. The distribution of log&lt;sub&gt;10&lt;/sub&gt; MoM values of maternal hemodynamic parameters in cases of PE and unaffected pregnancies, and the association between these hemodynamic parameters and GA at delivery, were assessed. The risks of preterm PE (delivery before 37 weeks) and any-onset PE (delivery at any time) were reassessed using Bayes' theorem after maternal hemodynamic parameters were added to the FMF triple test. The screening performance for preterm PE and any-onset PE was determined by the area under the receiver-operating-characteristics curve (AUC) and detection rate at a 10% fixed false-positive rate (FPR). Differences in AUC (ΔAUC) were assessed using DeLong's test.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;A total of 743 cases were analyzed, of whom 39 (5.2%) subsequently developed PE, including 29 (3.9%) cases of preterm PE and 10 (1.3%) cases of term PE. Mean log&lt;sub&gt;10&lt;/sub&gt; SVR MoM was significantly higher in cases of preterm PE and any-onset PE compared with unaffected pregnancies. Mean log&lt;sub&gt;10&lt;/sub&gt; SV MoM and log&lt;sub&gt;10&lt;/sub&gt; CO MoM were significantly lower in cases of preterm PE and any-onset PE compared with unaffected pregnancies. Mean log&lt;sub&gt;10&lt;/sub&gt; HR MoM was not significantly different between the study groups. Mean log&lt;sub&gt;10&lt;/sub&gt; CO MoM and log&lt;sub&gt;10&lt;/sub&gt; SVR MoM were not significantly correlated with GA at delivery in preterm PE and any-onset PE.

Therefore, the examination of lymph nodes is an essential part of the ultrasound evaluation in patients with known or suspected gynecological malignancy. The lymph nodes most frequently involved in gynecological malignancy (apart from vulvar cancer) are parietal (retroperitoneal) and visceral abdominopelvic lymph nodes. In advanced disease, more distant lymph-node regions, such as the inguinal, axillary and supraclavicular lymph nodes, can also be involved. The standardized description of lymph nodes has been published previously by the Vulvar International Tumor Analysis (VITA) collaborative group.
