RESUMO
INTRODUCTION: The emergence of handheld ultrasound devices capable of connecting to cell phones or tablets heralds a significant advancement in medical technology, particularly within the field of obstetrics. These devices offer the promise of immediate bedside ultrasound examinations, potentially revolutionizing patient care by enabling fetal assessments in diverse settings. MATERIAL AND METHODS: This prospective study aimed to validate the reliability of non-piezo, chip-based handheld ultrasound devices in clinical obstetric practice. Conducted in a university hospital obstetric ward, the study included 100 pregnant women between 17 and 41 weeks of gestation. Participants underwent ultrasound examinations using both conventional and portable point-of-care ultrasound (POCUS) devices to compare the accuracy in estimating fetal weight and other parameters, such as cardiac activity, fetal presentation, placental location, and amniotic fluid volume. The reliability and agreement between the devices were assessed using intraclass correlation coefficients, Bland-Altman plots, and Pearson correlation coefficients. RESULTS: The results show a near-perfect agreement (0.98) and correlation (r = 0.98, p < 0.001) for estimated fetal weight and most biometry measurements between the two types of ultrasound devices, with slight deviations in head circumference and amniotic fluid index measurements. Subgroup analysis revealed variations in agreement and correlation rates with higher BMI and advanced gestational age, indicating areas for further refinement. CONCLUSIONS: These findings affirm the high reliability of handheld ultrasound devices for basic obstetric ultrasound evaluations, supporting their integration into daily clinical practice. This technology improves the flexibility and immediacy of prenatal care, although further research is needed to optimize its application across patient populations and treatment settings.
RESUMO
BACKGROUND: Ultrasound (US) has become integral to obstetrics and gynecology (Ob/Gyn), necessitating proficient training during residency. Despite its clinical importance, there is a perceived gap in the quality and structure of postgraduate ultrasound education in Germany. METHODS: A cross-sectional survey was conducted among Ob/Gyn residents in Germany from October 2023 to March 2024, using the LimeSurvey platform. The survey, distributed via email, social media, and physical flyers, garnered 211 participants, with 115 completing all sections. The questionnaire covered demographic details, US training experiences, and the perceived importance of US in clinical practice. RESULTS: Although US was highly valued by respondents, with an average of 26.1% of their clinical activity devoted to it, there was significant dissatisfaction with the training quality. Key issues included inadequate supervision, the necessity of self-training, and low participation in certification courses. Despite 93.0% awareness of professional US organizations like the German Society for Ultrasound in Medicine (DEGUM), engagement with structured training programs was minimal. DISCUSSION: The study highlights a critical need for standardized US training protocols and curricular reform in Ob/Gyn residencies in Germany. The discrepancy between the recognized importance of US and the quality of training indicates a pressing need for improvements. Addressing these gaps through comprehensive, structured educational reforms could significantly enhance the proficiency and confidence of future Ob/Gyn specialists, ultimately improving patient care.
RESUMO
OBJECTIVE: In our center, we observed an increased frequency of right aortic arch (RAA) with an agenesis of the ductus arteriosus (ADA) in prenatally diagnosed tetralogy of Fallot (ToF) and its variations. This study aimed to determine whether there is an association of RAA and ADA in fetuses with ToF. Distribution of genetic anomalies and impact on postnatal outcome were further evaluated. METHOD: Single-center retrospective observational study including pregnancies with prenatal diagnosis of ToF from 2010 to 2023. All cases were subdivided into ToF with pulmonary stenosis (PS) and pulmonary atresia (PA). Clinical and echocardiographic databases were reviewed for pregnancy outcome, genetic anomalies, and postnatal course. RESULTS: The cohort included 169 cases, 124 (73.4%) with ToF/PS and 45(26.6%) with ToF/PA. Agenesis of the ductus arteriosus was significantly associated with RAA in both subtypes of ToF (p = 0.001) compared to left aortic arch and found in 82.5% (33/40) versus 10.7% (9/84) of fetuses with ToF/PS and in 57.1% (8/14) versus 12.9% (4/31) of fetuses with ToF/PA. In both ToF/PS and ToF/PA, RAA/ADA versus RAA/patent DA revealed a significantly higher risk for the presence of genetic abnormalities, especially microdeletion 22q11.2, major aorto-pulmonary collateral arteries and a shorter time to complete surgical repair. CONCLUSION: We demonstrated a significantly increased frequency of RAA/ADA in patients with prenatally diagnosed ToF. Although this association revealed no significant impact on overall survival, the prenatal detection of RAA/ADA has implications for counseling, genetic evaluation and postnatal management.

BACKGROUND: Academic advancement of the midwifery profession highlights the need to establish standardized qualifications in obstetric ultrasound diagnosis, being a central part of prenatal care. Thus, introduction of an evidence-based training program is warranted. We aimed to reviewed curriculum designs used in midwifery ultrasound education. METHODS: A systematic literature research was conducted. Embase, PubMed and Google Scholar database was reviewed for publications using the terms "[midwife], [midwives], [midwifery students], [obstetric ultrasound], [midwife sonographer] and [education], [teaching], [program], [course], [curriculum] and [learning]". Papers with full description of curriculum designs or educational programs on obstetrical ultrasound for midwives were included and scrutinized against pre-defined criteria according to the PICO (Population, Intervention, Comparator, Outcomes) scheme. RESULTS: 29 publications were included. Studies demonstrated a significant disparity according to course concepts being used. Differing parameters included: Duration, structure, learning approaches, course content, examination concepts and target groups (practising midwives vs. midwives in education). CONCLUSION: An evidence-based ultrasound educational program for midwives remains to be developed, including further educational guidelines. Clinical applications by midwives, as well as the distinctions from medical practise, particularly in terms of legal considerations, needs to be defined.

BACKGROUND: We used two 3D ultrasound volumes of fetal heads at 13 weeks to create live-size 3D-printed phantoms with a view to training or assessment of diagnostic abilities for normal and abnormal nuchal translucency measurements. The phantoms are suitable for use in a water bath, imitating a real-life exam. They were then used to study measurement accuracy and reproducibility in examiners of different skill levels. METHODS: Ultrasound scans of a 13 + 0-week fetus were processed using 3D Slicer software, producing a stereolithography file for 3D printing. The model, crafted in Autodesk Fusion360™, adhered to FMF guidelines for NT dimensions (NT 2.3 mm). Additionally, a model with pathologic NT was designed (NT 4.2 mm). Printing was performed via Formlabs Form 3® printer using High Temp Resin V2. The externally identical looking 3D models were embedded in water-filled condoms for ultrasound examination. Eight specialists of varying expertise levels conducted five NT measurements for each model, classifying them in physiological and abnormal models. RESULTS: Classification of the models in physiological or abnormal NT resulted in a detection rate of 100%. Average measurements for the normal NT model and the increased NT model were 2.27 mm (SD ± 0.38) and 4.165 mm (SD ± 0.51), respectively. The interrater reliability was calculated via the intraclass correlation coefficient (ICC) which yielded a result of 0.883, indicating robust agreement between the raters. Cost-effectiveness analysis demonstrated the economical nature of the 3D printing process. DISCUSSION: This study underscores the potential of 3D printed fetal models for enhancing ultrasound training through high inter-rater reliability, consistency across different expert levels, and cost-effectiveness. Limitations, including population variability and direct translation to clinical outcomes, warrant further exploration. The study contributes to ongoing discussions on integrating innovative technologies into medical education, offering a practical and economical method to acquire, refine and revise diagnostic skills in prenatal ultrasound. Future research should explore broader applications and long-term economic implications, paving the way for transformative advancements in medical training and practice.

RESUMO
BACKGROUND: Critical aortic stenosis (AS) in fetuses may progress to hypoplastic left heart syndrome (HLHS) with need for postnatal single ventricular (SV) palliation. Fetal aortic valvuloplasty (FAV) is performed to achieve postnatal biventricular (BV) circulation. However, the impact of FAV on fetal myocardial function is difficult to measure. Prediction of postnatal circulatory status and, therefore, counseling is challenging. METHODS: Retrospective study of fetuses with critical AS who underwent FAV. Global Longitudinal Peak Systolic Strain (GLPSS) of the left ventricle (LV) and right ventricle (RV) were retrospectively analyzed before and after intervention. Fisher's Exact Test and Mann-Whitney-U Test were used for univariant statistical analysis. RESULTS: 23 fetuses with critical AS were included. After intervention fetuses demonstrated more negative LV-GLPSS mean values post- vs. pre-intervention (- 5.36% vs. - 1.57%; p < 0.05). RV-GLPSS was decreased in all fetuses, there was no peri-interventional change. 20 fetuses were born alive. Postnatally, 10 had BV and 10 SV circulation. Improved post-interventional LV-GLPSS strain values correlated with BV outcome (p < 0.05). Pre-interventional continuous LV-GLPSS values correlated with postnatal SV vs. BV outcome (p < 0.05). CONCLUSION: In some fetuses, LV myocardial function assessed by speckle tracking echocardiography (STE) improves after FAV. Improved post-interventional LV-GLPSS correlates with biventricular postnatal outcome. Furthermore, pre-interventional LV- and RV-GLPSS correlate with postnatal outcome. Further studies are needed to asses, if pre-interventional STE parameters might predict which fetuses will benefit from FAV with postnatal BV circulation.

AIM: Less than a dozen cases of psoas abscesses in pregnancy have been described in the literature. We reviewed the literature when treating a patient with a psoas abscess after ipsilateral double J-ureteral stent placement (in the following: "double J-stent") due to infected hydronephrosis. METHODS: In January 2022, this review was searched using the Pubmed/MEDLINE database and the mesh terms "Psoas Abscess" AND "Pregnancy". Studies were included in any language and of all years, describing a psoas abscess during pregnancy. When patients did not have a psoas abscess, the abscess occurred after pregnancy, or when there was no full text available, the article was excluded. MAIN RESULTS: Ten case reports about patients with psoas abscesses during pregnancy were included. The classical symptomatic triad of psoas muscle abscess included lower back pain, limping and persistent fever with daily spikes. However, in most cases, not all three symptoms can be found. Especially, fever is absent in more than half of the patients. Psoas abscesses are described between 13 and 39 weeks of gestation. Primary psoas abscesses with haematogenous spread are more common during pregnancy than secondary with spread per continuitatem. In the literature, the main reasons for psoas abscess are spinal tuberculosis, drug abuse or underlying diseases such as Crohn's disease. It is not uncommon for the definite cause to be unclear. Regarding the patient's symptoms, pyelonephritis is often considered a possible aetiology. In general, the main treatment options include antibiotic treatment and abscess drainage. There is no higher caesarean section rate, and no negative outcome for the foetus has been described. CASE PRESENTATION: In our patient, a 38-year-old obese Caucasian woman, who had received a left double J-stent for infected hydronephrosis at 15 weeks of gestation, we successfully treated a psoas abscess of 20 × 10 cm with a sonographically assisted abscess drainage and antibiotics. The further course of pregnancy and the elective repeat caesarean section at 38 + 0 weeks of gestation were without any problems. Double J-stent placement and laser stone lithotripsy during puerperium were performed because of recurrent urolithiasis. CONCLUSIONS: Although rare, psoas abscesses can occur during pregnancy, and it has often been treated surgically in the past. A psoas abscess as a complication after infected hydronephrosis and intervention during pregnancy has never been reported in the literature. Even for obese patients, minimally invasive therapy may be a treatment option that has rarely been reported in the literature.

PURPOSE: In adults and fetuses, N-terminal pro-B-type natriuretic peptide (NT-proBNP) is a marker of cardiac failure and myocardial remodelling. We examined the effect of anemia and intrauterine transfusion (IUT) on NT-proBNP concentrations in fetuses with anemia and established gestational age-dependent reference values of a control group. METHODS: We analyzed NT-proBNP levels in anemic fetuses that underwent serial intrauterine transfusions (IUT), focusing on different causes and severity of anemia and comparing the results to a non-anemic control group. RESULTS: In the control group, the average NT-proBNP concentration was 1339 ± 639 pg/ml, decreasing significantly with increasing gestational age (R = - 74.04, T = - 3.65, p = 0.001). Subjects had significantly higher NT-proBNP concentrations before initiation of IUT therapy (p < 0.001), showing fetuses with parvovirus B19 (PVB19) infection having the highest concentrations. Hydropic fetuses also showed an increased NT-proBNP concentration compared to non-hydropic fetuses (p < 0.001). During the course of therapy, NT-proBNP concentration before subsequent IUT decreased significantly from pathologically high levels, while MoM-Hb and MoM-MCA-PSV remained pathological. CONCLUSION: NT-pro BNP levels in non-anemic fetuses are higher than in postnatal life, decreasing with ongoing pregnancy. Anemia is a hyperdynamic state and its severity correlates with circulating NT-proBNP levels. Highest concentrations occur in fetuses with hydrops and with PVB19 infection, respectively. Treatment by IUT leads to a normalisation of NT-proBNP concentrations, so the measurement of its levels may be useful in therapy monitoring.

OBJECTIVE: Evaluation of course and outcome of pregnancies with prenatally diagnosed fetal urinoma in a single center over a 20-year period. METHODS: Retrospective study including all prenatally suspected or diagnosed fetal urinomas. Cases were analyzed by ultrasound findings during pregnancy, comparing urinomas caused by lower urinary tract obstruction (LUTO) and ureteropelvic or ureterovesical junction obstruction (UPJO/UVJO). Course of pregnancy and outcomes were compared according to the underlying etiology. RESULTS: 87 cases of fetal urinomas were identified between 2002 and 2022. The underlying etiology was LUTO in 56.3% and UPJO/UVJO in 43.7%. Complications mainly included oligo- or anhydramnios, thoracic hypoplasia as well as associated renal abnormalities. Postnatally, loss of function (LOF) in kidneys affected by urinomas was seen in 78.6% of children overall, but significantly more often in cases of UPJO/UVJO than in LUTO (86.2% vs. 70.2%, p < 0.05). CONCLUSION: Association of prenatal urinoma and postnatal LOF of the affected kidney is high, especially in cases caused by UPJO/UVJO. In survivors with urinoma caused by UPJO/UVJO, the general prognosis is excellent if the contralateral kidney was normal. In survivors with urinomas caused by LUTO, long-term prognosis depends on postnatal renal and pulmonary function.

Cesarean section (CS) is the most widely performed and one of the most painful surgeries. This study investigated postoperative pain after CS using patient-related outcomes (PROs) to identify risk factors for severe pain. The secondary outcome was to evaluate the influence of surgery indication (primary CS (PCS) vs. urgent CS (UCS)). This multi-center, prospective cohort study included data submitted to the pain registry "quality improvement in postoperative pain treatment" (QUIPS) between 2010 and 2020. In total, 11,932 patients were evaluated. Median of maximal pain was 7.0 (numeric rating scale (NRS) 0 to 10); 53.9% suffered from severe pain (NRS ≥ 7), this being related to impairment of mood, ambulation, deep breathing and sleep, as well as more vertigo, nausea and tiredness (p < 0.001). Distraction, relaxation, mobilization, having conversations, patient-controlled analgesia (PCA) and pain monitoring were shown to be protective for severe pain (p < 0.001). Maximal pain in PCS and UCS was similar, but UCS obtained more analgesics (p < 0.001), and experienced more impairment of ambulation (p < 0.001) and deep breathing (p < 0.05). Severe pain has a major effect on daily-life activities and recovery after CS, and depends on modifiable factors. More effort is needed to improve the quality of care after CS.
RESUMO
Artificial intelligence (AI) has gained prominence in medical imaging, particularly in obstetrics and gynecology (OB/GYN), where ultrasound (US) is the preferred method. It is considered cost effective and easily accessible but is time consuming and hindered by the need for specialized training. To overcome these limitations, AI models have been proposed for automated plane acquisition, anatomical measurements, and pathology detection. This study aims to overview recent literature on AI applications in OB/GYN US imaging, highlighting their benefits and limitations. For the methodology, a systematic literature search was performed in the PubMed and Cochrane Library databases. Matching abstracts were screened based on the PICOS (Participants, Intervention or Exposure, Comparison, Outcome, Study type) scheme. Articles with full text copies were distributed to the sections of OB/GYN and their research topics. As a result, this review includes 189 articles published from 1994 to 2023. Among these, 148 focus on obstetrics and 41 on gynecology. AI-assisted US applications span fetal biometry, echocardiography, or neurosonography, as well as the identification of adnexal and breast masses, and assessment of the endometrium and pelvic floor. To conclude, the applications for AI-assisted US in OB/GYN are abundant, especially in the subspecialty of obstetrics. However, while most studies focus on common application fields such as fetal biometry, this review outlines emerging and still experimental fields to promote further research.
RESUMO
BACKGROUND: Cordocentesis is used in clinical situations in which lower-risk diagnostic procedures do not deliver the desired results. The aim of this study was to evaluate the risk for procedure-related complications and fetal loss in correlation to maternal risk factors. METHODS: This is a multicenter retrospective study investigating the complications, risk factors and perinatal outcome of diagnostic cordocentesis between 1998 and 2019 in three different centers. RESULTS: A total of 1806 cordocenteses were performed and procedure-related complications (IUFD within 48 h, contractions, bradycardia, unsuccessful puncture, chorioamniotic separation) were noted in 1.6% of cases. Fetuses with chromosomal aberrations, intrauterine growth restriction and hydropic fetuses had a significantly higher rate of fetal loss compared to other indications. Fetal blood sampling (FBS) performed before 17+0 weeks of gestation was associated with a higher risk of procedure-related complications. Maternal BMI ≥ 40 increased the risk for fetal loss, whereas maternal age, number of previous miscarriages, number of previous abortions, history of vaginal bleeding or nicotine abuse did not affect the risk for complications or overall fetal loss rate. CONCLUSIONS: In the hands of experienced operators, FBS is a safe way to further fetal diagnostics, and the risk of complications is low.
RESUMO
To summarize the evidence on non-hemorrhagic adrenal infarction (NHAI) and identify questions arising in diagnosis and management, cases in the PubMed database were merged with our case series. A total of 92 publications were retrieved, 15 of which reported on NHAI during pregnancy. Including the four in our case series, 24 cases have been described so far. Severe, unremitting pain requiring opioid analgesia was the leading symptom, often combined with nausea and vomiting. Laboratory results were non-contributory in most cases. Diagnosis was established via MRI in nine cases (37.5%) and via CT in six (25%); nine patients (37.5%) underwent both investigations. Location was predominantly on the right side (n = 16, 66.7%). In addition to analgesia, anticoagulation with heparin was commenced in 18 cases (75%). When thrombophilia screening was performed, major thrombogenic polymorphisms were detected in six cases (33.3%). One woman developed signs of adrenal insufficiency. The reported perinatal outcome was unremarkable. Unilateral NHAI has emerged as a rare but important cause of severe abdominal pain in pregnancy. The threshold to perform an MRI in pregnant women with characteristic clinical findings should be low. To prevent fetal radiation exposure, diagnostic imaging via CT should be avoided. In addition to symptomatic treatment with opioid analgesia, initiation of anticoagulant treatment should be strongly considered.
RESUMO
OBJECTIVE: to assess the course and outcome of fetuses affected by primary cardiomyopathy (CM). METHODS: Retrospective study of 21 cases with prenatal diagnosis of a primary CM in one tertiary center over a period of 20 years. Charts were reviewed for echocardiographic findings, pregnancy outcome, and postnatal course. The utility of prenatal evaluation was discussed. RESULTS: The mean gestational age (GA) at diagnosis was 26.7 (±5.1) weeks. A total of 33.3% (7/21) had associated anomalies. Genetic etiology was confirmed in 50.0% (10/20, with one case lost to follow up). The overall survival rate of the entire study population was 40% (8/20) including termination of pregnancy in 20% (4/20) and an intrauterine mortality rate of 5% (1/20). Of the initial survivors (n = 15), a neonatal and early infant mortality rate of 46.7% (7/15) was calculated. Prenatal isolated right ventricular involvement was the only identified significant parameter for survival (p = 0.035). Four phenotypical groups were identified: 42.9% (9/21) hypertrophic (HCM), 38.1% (8/21) dilated (DCM), 14.3% (3/21) isolated noncompaction (NCCM), and 4.8% (1/21) restrictive CM (RCM). Fetuses assigned to isolated NCCM revealed a 100% survival rate. CONCLUSION: Prenatal detection is feasible but needs to a introduce classification method for better consulting and management practices. A poor outcome is still observed in many cases, but an increase in examiners' awareness may influence optimal multispecialized care.
RESUMO
BACKGROUND: Portal hypertension in pregnancy is characterized by an increased perinatal and maternal complication rate. The purpose of this study was to evaluate the perinatal and maternal outcomes of these high-risk pregnancies at our tertiary center. METHODS: We identified pregnancies with portal hypertension in our departmental database for the years 2013 to 2021. The medical history and perinatal and maternal data were extracted from medical records. RESULTS: Eleven cases were identified. In pregnancy, delivery and postpartum, complications occurred in 72.7% of cases and included among others ascites, subclavian thrombosis, variceal-ligation-induced ulcer bleeding and postoperative hemorrhage. The cesarean delivery rate was 72.7% (n = 8); five of these were done for obstetric or fetal indications. The rate of preterm birth and admissions to neonatal intensive care unit were high (54.5% and 45.5%, respectively). CONCLUSIONS: Our case series substantiates the high maternal and perinatal complication rates seen in portal hypertension. The prevention of thromboembolic and bleeding complications was the main challenge. Care by an interdisciplinary team of experts is crucial for a successful perinatal and maternal outcome.
RESUMO
PURPOSE: Evaluating procedure-related complications and perinatal outcomes after intrauterine transfusion (IUT) before or after 20+0 weeks of gestation in fetuses with severe anemia due to intrauterine human parvovirus B19 infection. METHODS: A retrospective study investigating fetuses requiring IUT for fetal Parvo B19 infection in two tertiary referral centers between December 2002 and December 2021. Procedure-related complications, intrauterine fetal death (IUFD), and perinatal outcome were correlated to gestational age (GA) at first IUT, the presence of hydrops and fetal blood sampling results. RESULTS: A total of 186 IUTs were performed in 103 fetuses. The median GA at first IUT was 19+3 (13+0-31+4) weeks of gestation. IUFD occurred in 16/103 fetuses (15.5%). Overall survival was 84.5% (87/103). Hydrops (p = 0.001), lower mean hemoglobin at first IUT (p = 0.001) and low platelets (p = 0.002) were strongly associated with IUFD. There was no difference observed in fetuses transfused before or after 20+0 weeks of gestation. CONCLUSION: IUT is a successful treatment option in fetuses affected by severe anemia due to parvovirus B19 infection in specialized centers. In experienced hands, IUT before 20 weeks is not related to worse perinatal outcome.

PURPOSE: To assess the spectrum of associated cardiac anomalies, the intrauterine course, and postnatal outcome of fetuses with double inlet ventricle (DIV). METHODS: Retrospective analysis of prenatal ultrasound of 35 patients with DIV diagnosed between 2003 and 2021 in two tertiary referral centers in Germany. All fetuses underwent fetal echocardiography and a detailed anomaly scan. Postnatal outcome and follow-up data were retrieved from pediatric reports. RESULTS: 33 cases of DIV were correctly diagnosed prenatally. 24 fetuses (72.7%) had a double inlet ventricle with dominant left (DILV), 7 (21.2%) with dominant right ventricular morphology (DIRV), and 2 cases (6%) with indeterminate morphology (DIIV). 4 (16.6%) were Holmes hearts. 5 of the 7 fetuses (71.4%) with DIRV had a double outlet right ventricle (DORV). Malposition of the great arteries was present in 84.8%. Chromosomal abnormalities were absent. Termination of pregnancy was performed in 8 cases (24.2%). 24 fetuses (72.7%) were live-born. 5 (20.8%) were female and 19 (79.2%) were male. The median gestational age at birth was 38+2.5 weeks. All but one child received univentricular palliation. The median follow-up time was 5.83 years with an adjusted survival rate of 91.6% (22 of 24 live-born children). There was one case of Fontan failure at 15.7 years. CONCLUSION: DIV remains a major cardiac malformation although both prenatal diagnostics and cardiac surgery have improved over the years. The course of pregnancy is commonly uneventful. All children need univentricular palliation. The children are slightly physically limited, develop a normal intellect, and attend school regularly.
