This study aimed to ascertain the efficacy of systematic ultrasound screening for fetal structural abnormalities. Method This retrospective analysis examined the results of first-trimester systematic ultrasound screenings performed of 30,336 fetuses between June 2019 to and 2022 and compared them with second- and third-trimester ultrasound screening, postpartum examination, and post-mortem examination results. Results Among the 30,336 fetuses, 4.1% (1,240) had structural abnormalities, of which 37.1% (460/1,240) were severe. Overall, 32.2% (399/1,240) of the structural abnormalities were detected via the systematic ultrasound screening, among which 79.7% (318/399) were severe. Of the 318 fetuses with severe abnormalities, 69.1% (220) featured nuchal translucency (NT); 21.1% (220/1,240) of the fetuses with structural abnormalities presented with increased NT versus 46.1% of those with severe structural abnormalities. Of the structural abnormalities detected by the systematic ultrasound screening, 54.6% featured increased NT. Systematic ultrasound screening had a sensitivity of 32.2% and specificity of 99.82% for the identification of fetal structural abnormalities. Areas by sensitivity level were as follows: ≥80%, anterior abdominal wall abnormalities, syndromes, edema/coelomic hydrops; 50–80%, nervous system structural abnormalities; 30–50%, other abnormalities and limb and skeleton structural abnormalities; and < 30%, congenital heart defects and facial, gastrointestinal tract, urogenital system, and thoracic and lung-related structural abnormalities. Combined screening exhibited higher sensitivity than systematic ultrasound screening alone (P < 0.001). Conclusion Systematic ultrasound screening detected most serious fetal structural abnormalities; however, its efficacy varied significantly among systems and diseases. Increased NT may be an important indicator of serious structural abnormalities. Furthermore, combined screening of fetal structural abnormalities has higher efficacy. Health sciences/Medical research Health sciences/Medical research/Paediatric research Health sciences/Diseases first trimester fetus severe structural abnormality malformation Figures Figure 1 Figure 2 Why do we conduct this research? Here we employed a 20-plane systematic ultrasound protocol (systematic ultrasound screening) in the first trimester to detect the structures of more than 30,000 fetuses and investigated its diagnostic efficiency. What was the key discovery? Systematic ultrasound screening can identify 32.2% of fetal structural abnormalities and 69.1% of severe fetal structural abnormalities. The combination of systematic ultrasound screening and second-trimester ultrasound screening (combined screening) can more effectively detect fetal structural abnormalities. The rate of increased nuchal translucency in fetuses with structural abnormalities, particularly in those with severe structural abnormalities, was significantly elevated. What does this study add to what is already known? The diagnostic performance of systematic ultrasound screening is demonstrated herein in a large, unselected cohort. Introduction Fetal structural abnormalities are defined as anatomical malformations caused by the abnormal development of organs or body parts that can lead to the absence, partial formation, or abnormal formation of structures 1 . Some structural abnormalities may lead to metabolic diseases, functional impairments, mental disorders, and other complications 2 . Effective treatment approaches for severe fetal structural abnormalities are currently lacking 3 . Advancing the screening time for fetal structural abnormalities in early pregnancy can offer parents of affected fetuses more time to undertake prognostic counseling and make decisions 4 , thereby minimizing maternal physical and psychological harm 5 . Fetal structural abnormalities are extensive and diverse during the first trimester. The detection rate of fetal structural abnormalities may differ based on the ultrasound screening approach, population diversity, ultrasound operator, varying prevalence of congenital diseases, and geographical location diversity. Although having a well-defined and standardized inspection process is highly important, most existing studies on ultrasound evaluations in the first trimester focused on examining fetal anatomy 6 . In contrast, there are few large-sample studies of standardized ultrasound examination protocols and diagnostic performance validation, and the spectrum and severity distribution of fetal structural abnormalities are still being explored. This study performed systematic ultrasound screenings of more than 30,000 fetuses during early pregnancy to investigate the disease spectrum, chromosomal abnormalities, increased nuchal translucency (NT), and pregnancy outcomes of fetuses with structural abnormalities. Moreover, it aimed to offer a foundation for the prenatal ultrasound diagnosis of fetal structural abnormalities during the first trimester to guide prenatal and perinatal consultations and clinical decision-making. Materials and Methods Study cohort Between June 2009 and June 2022, our center screened 32,253 women with singleton pregnancies at 11 and 13 + 6 weeks' gestation for fetal structural abnormalities. The pregnant women were 16–50 (mean, 30.02 ± 4.07) years of age. The median gestational age was 13.14 (interquartile range, 12.71–13.71) weeks, while the median crown-rump length was 6.8 (interquartile range, 6.2–7.5) cm. Screening methods and instruments A systematic ultrasound screening protocol consisting of 20 planes (Fig. 1 ) was adopted to perform routine structural screenings during the first trimester for all pregnant women undergoing prenatal examinations at our center. The clinical data were subsequently analyzed retrospectively. This study was approved by the Ethics Committee of Fujian Provincial Maternal and Child Health Hospital,and all methods were performed in accordance with the relevant guidelines and regulations 7 – 11 . The systematic ultrasound screening protocol employed at our center was primarily revised with reference to the International Society of Ultrasound in Obstetrics and Gynecology (ISUOG) first- and second-trimester fetal ultrasound screening guidelines 7 , 8 . Initially, key indicators such as crown–rump length, NT, and ductus venosus blood flow spectra were measured. Subsequently, a sequential scan was performed to evaluate the fetal anatomical structures, including general morphology, craniofacial features, thorax, heart, abdomen, limbs, and spine. In cases in which transabdominal ultrasonography yielded unsatisfactory image quality, a high-frequency linear array probe was employed, while transvaginal ultrasonography was conducted with additional informed consent from the pregnant woman. At our center, all ultrasound physicians responsible for fetal structural screenings are required to undergo rigorous training. High-resolution ultrasound equipment was used herein, including the GE Voluson E8, GE Voluson E10, PHILIPS EPIQ7, Mindray Resona R9, and SAMSUNG WS80A. A transabdominal convex array probe was employed at frequencies of 4–5 MHz, whereas a transvaginal probe was operated at frequencies of 6–10 MHz. Ultrasound follow-up and management When ultrasound revealed or suggested fetal structural abnormalities during the first trimester, pregnant women were recommended to receive prenatal consultations and undergo follow-up ultrasound and genetic tests, including chorionic villus sampling before 14 weeks' gestation, amniocentesis at 16–28 weeks' gestation, and umbilical cord blood sampling after 28 weeks' gestation. During the middle and late stages of pregnancy, ultrasound examinations were performed to perform a detailed structural assessment of the fetus according to the ISUOG guidelines for fetal mid-pregnancy ultrasound screenings 8 . Structurally abnormal fetuses in continuing pregnancies were subjected to regular ultrasound examinations and prepared for postpartum treatment. Structurally abnormal fetuses in terminated pregnancies were subjected to pathological verification with the family's consent. All routine neonatal examinations were performed by prenatal clinicians. If a fetus with identified structural abnormalities continued to develop normally, dynamic ultrasound evaluations were performed regularly along with preparations for postpartum interventions. Timely postpartum treatments were instituted when necessary. In cases in which a pregnancy was terminated, pathological verification was performed once informed consent was from the pregnant woman and her family. All routine neonatal examinations were performed by prenatal clinicians. Additionally, telephone follow-ups were performed on those patients who did not undergo second- or third-trimester ultrasounds or deliver their babies within our facility; their examination results and pregnancy outcomes were documented accordingly. Inclusion and exclusion criteria The inclusion criteria were as follows: gestational age of 11–13 + 6 weeks or a crown–rump length of 45–84 mm. A comprehensive structural assessment was conducted using the first-trimester systematic ultrasound screening method. The exclusion criteria were as follows: multiple pregnancy, lack of second- and third-trimester ultrasound examination results, absence of newborn birth defect screening, lost contact, soft markers, small cerebellar transverse diameter (>-2 standard deviations), imbalanced cardiac chamber proportions, imbalanced large-artery proportions, indeterminate enlargement of the liver and spleen, isolated calcification of the liver without evidence of infection, enhanced renal parenchymal echoes, chromosomal abnormalities without accompanying structural defects, postnatally identified atrial septal defects, patent foramen ovale, and patent ductus arteriosus. Results determination We analyzed all structural abnormalities diagnosed during the pre- and neonatal periods. In the verification of the prenatal ultrasound diagnosis results, the cases subjected to autopsy were judged by the autopsy results. After childbirth, the postpartum examination results served as the standard. If neither dataset was available, the last ultrasound diagnosis made during pregnancy was used as the reference. In cases subjected to multiple ultrasound examinations, the final diagnosis made by a group of physicians was analyzed. Multiple structural abnormalities were classified by the most severe lesion. We defined severe malformations as those that were either lethal or complicated survival after birth as well as conditions that were survivable but had a poor prognosis and could still affect quality of life despite surgical or clinical intervention 9 – 11 . Statistical analysis SPSS 29.0 statistical software was used to analyze the collected data. Quantitative data following a normal distribution are described as be mean ± S.D., while count data are described using frequencies and proportions. The chi-squared or Fisher's exact probability test was used to detect statistically significant intergroup differences. We calculated the diagnostic sensitivity, specificity, positive predictive value, negative predictive value, and Jaccard index for the systematic and combined screening methods. McNemar's test was used to compare the sensitivity differences between them. Statistical significance was set at P < 0.05. Results The detection of structural abnormalities in prenatal and postnatal periods A total of 32,253 singleton pregnancies were subjected to structural ultrasound screenings at 11–13 + 6 weeks over a 3-year period; among them, no outcomes data were available for 1,917 (5.94%). Among the 30,336 fetuses for whom outcomes data were available, 1,240 (4.1%) had at least one structural abnormality (Table 1 ); of them, 460 (37.1%) had severe structural abnormalities.

identified 452 cases of structural abnormalities. Among them, 53 (11.7%) were classified as false-positive diagnoses due to misdiagnosis or intrauterine evolution; thus, the actual detection rate of structural abnormalities in the first trimester was 32.2% (399/1,240), and the detection rate of severe structural abnormalities was 79.7% (318/399), accounting for 69.1% (220/318) of all severe structural abnormalities. This included 100% anterior abdominal wall structural abnormalities, 95.7% syndromes, 53.2% nervous system structural abnormalities, 32.7% limb and skeletal structural abnormalities, 25.6% congenital heart defects, 10.8% gastrointestinal tract structural abnormalities, 8.1% urogenital system structural abnormalities, and 3.6% thoracic and lungs structural abnormalities(Table 1 ). A total of 628 (50.6%) cases were detected in the second trimester, 71 (5.7%) in the third trimester, and 142 (11.5%) during the postpartum period. Prenatal ultrasound screenings detected 88.5% of the fetal structural abnormalities. Of all structural abnormalities, 751 (60.6%) resulted in live births (LB), 467 (37.7%) in termination of pregnancy (TOP), and 22 (1.7%) in intrauterine death (IUD). Among the cases detected in the first trimester, 56 (14.1%) resulted in LB, 332 (83.2%) in TOP, and 11 (2.7%) in IUD. Among the cases detected in the second trimester, 490 (78.0%) resulted in LB, 127 (20.2%) in TOP, and 11 (1.8%) in IUD. Among the cases detected in the third trimester, 63 (88.7%) resulted in LB, eight (11.3%) in TOP, and 11 (1.7%) in IUD (Fig. 2 ). Fetal structural abnormalities and NT Among 30,336 fetuses, 1,453 (4.7%) presented with increased NT (exceeding the 95th percentile), 21.1% (261/1,240) had structural abnormalities and increased NT, and 4.1% (1,192/29,096) had no structural abnormalities but increased NT (P < 0.001). The rate of increased NT was 46.1% (212/460) among fetuses with severe structural abnormalities versus 5% (39/780) among those with non-severe structural abnormalities (P < 0.001). Nevertheless, no significant difference was observed between fetuses with non-severe versus no structural abnormalities (P = 0.21). Among the structural abnormalities detected by systematic ultrasound screening, 54.6% (218/399) featured increased NT; these rates were 61.6% (196/318) among cases of severe structural abnormalities and 27.2% (22/81) among those with non-severe structural abnormalities. Among those with structural abnormalities detected during the second and third trimesters or postpartum, 5.1% (43/841) exhibited increased NT thickness, with a probability of 11.3% (16/142) in cases of severe and 3.9% (27/699) in cases of non-severe structural abnormalities. Among the various assessed systems, the highest incidence of increased fetal NT was recorded for edema/coelomic hydrops at 86.3% (63/73), whereas a lower incidence of 3.6% (1/28) was noted for thoracic and lung-related anomalies. Additionally, the incidence of an increased NT varied significantly across different systems (P < 0.05; Table 2 ).

Among those with structural abnormalities, 14.2% (44/309) had chromosomal abnormalities, with trisomy 21 and chromosome 9 inversion being the most prevalent. In contrast, among the 2,913 fetuses without structural abnormalities, the incidence of chromosomal abnormalities was 8.0% (234/2913), with chromosome 9 inversion being the most commonly observed. The prevalence of chromosomal abnormalities was significantly higher in fetuses with versus without structural abnormalities (P < 0.001). Among the various examined systems, edema/coelomic hydrops had the highest incidence of chromosomal anomalies (41.7% [5/12]), followed by limb and skeletal structural abnormalities (35.7% [5/14]). Diagnostic efficacy of systematic ultrasound screening and combined screening The true-positive rate of systematic ultrasound screening was 88.3% (399/452), with a false-negative rate of 2.8% (841/29,884). The sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, negative likelihood ratio, and Youden index were 32.2%, 99.8%, 88.3%, 97.0%, 176.65, 0.68, and 0.32, respectively. Among the various systems, the diagnostic sensitivity of systematic ultrasound screening was > 80% for anterior abdominal wall abnormalities, syndromes, and edema/coelomic hydrops; 50–80% for nervous system structural abnormalities; 30–50% for limb, skeletal, and other structural abnormalities; and < 30% for thoracic and lung-related structural abnormalities, urogenital system structural abnormalities, gastrointestinal tract structural abnormalities, facial abnormalities, and congenital heart defects. The true-positive rate of the combined screening method was 70.6% (1,027/1,455), while the false-negative rate was 0.7% (213/28,881). The sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, negative likelihood ratio, and Youden index were 82.8%, 98.5%, 70.6%, 99.2%, 56.30, 0.17, and 0.81, respectively. The sensitivity and Youden index of the combined screening significantly exceeded those of the systematic ultrasound screening (P < 0.001). The sensitivity of the combined screening method for anterior abdominal wall and syndromic abnormalities was similar to that of the systematic ultrasound screening (P = 1.0), but the sensitivity was superior to that of systematic ultrasound screening in the remaining body systems (P < 0.001; Table 3 ).

The overall incidence of birth defects in China is 5.6% 13 .In our study, the total incidence of fetal structural abnormalities was 4.1%, a figure in line with that reported by Dulgherof and Oakley 14 , 15 but higher than that reported by Vayna 16 . This difference is mainly due to the fact that we incorporated minor structural abnormalities such as aberrant right subclavian artery and persistent left superior vena cava to offer a more comprehensive reflection of the composition of the structural abnormalities. Owing to the advancement of ultrasound equipment and physician experience, first-trimester screenings can offer detailed evaluations of fetal anatomical structures and identify abnormalities 12 , 17 , 18 , particularly severe structural abnormalities 19 – 21 . This contributes to the optimal management of abnormal pregnancies 22 , 23 .Significant variations exist among current studies in the sensitivity of detecting structural abnormalities during the first trimester 20 , 24 .We employed a 20-plane systematic ultrasound screening protocol featuring a mid-level detection sensitivity of 32.2% for fetal structural abnormalities. Variations in operator technical proficiency, regional disparities in disease prevalence, differences in follow-up duration, and the lack of standardized examination protocols can cause such differences 6 , 25 , 26 . The combined use of first- and second-trimester ultrasound screenings can effectively increase the sensitivity of fetal structural abnormality detection, particularly of the urogenital system, gastrointestinal tract, and thoracic and lung-related structural abnormalities, which have an extremely low sensitivity during the first trimester. In this study, 69.1% of the severe abnormalities were identified during the first trimester, a proportion similar to which Saltvedt et al. 9 reported that 69% of fatal lethal malformations can be detected during the 12–14 weeks' gestation.Syngelaki et al. 27 , 28 stated that the first-semester sensitivity for the detection of anencephaly, exencephaly, holoprosencephaly, gastroschisis, pentalogy of Cantrell, megacystis, and body stalk anomaly can reach 100%. In addition to the abnormalities mentioned above, this includes atrial septal defect, mitral valve atresia, hypoplastic left heart syndrome, hypoplastic right heart syndrome, aortic atresia, cloacal malformation, absence of the radius and ulna, and Meckel–Gruber syndrome. The sensitivity for the detection of structural abnormalities in the fetal anterior abdominal wall abnormalities, syndromes, and edema/serous cavity effusion during the first trimester exceeds 80%. This study revealed that anterior abdominal wall abnormalities had the highest detection sensitivity during the first trimester similar to that (95.6%) reported by Macedo 29 , which corroborates the perspective that, large abdominal wall defects are often observed during the first trimester. Most of these structural abnormalities can be detected during early pregnancy and should be a key focus of first-trimester screenings. We identified all serious malformations in the nervous system, including anencephaly, holoprosencephaly, and exencephaly, in the first trimester as reported by Hu et al. 27 , 30 . However, the sensitivity of the detection of spina bifida, agenesis of the corpus callosum, and Blake’s pouch cyst differ markedly; in fact, we did not uncover any instances of cerebellar dysplasia, the vein of Galen aneurysmal malformation, microcephaly, intracranial infection, or cyst of the septum pellucidum. This might be associated with operator proficiency level, physician comprehension of the disease, and the disease spectrum. The sensitivity for detecting fetal thoracic and lung-related structural abnormalities in the first trimester was the lowest among all systematic structural abnormalities, lower than the 9.7% and 18.4% reported by Liao 6 and Syngelaki 28 ,, 31 , respectively, the main reason may be that no diaphragmatic hernias were identified in the first trimester in our study. The diagnosis of diaphragmatic hernia in the first trimester depends on its size and degree of fetal intra-abdominal pressure 24 . Our study incorporated ventricular septal defect, persistent left superior vena cava, and aberrant right subclavian artery, which led to relatively low sensitivity for the detection of cardiac structural abnormalities in the first trimester. If these diseases are excluded, the sensitivity for detecting cardiac structural abnormalities in the first trimester can increase to 50.8%, consistent with the findings of Liao. In the first trimester, our study found a marginally higher detection rate of severe limb malformations than that reported by Syngelaki, a slightly higher detection rate of spinal malformations than that reported by Fong 31 , and a lower sensitivity for the detection of limb-shortening deformities than that reported by Liao. These phenomena might be related to the fact that, in our study, we merely observed the fetal limbs for morphological changes during early pregnancy and did not measure femoral and humeral lengths. It might also be associated with disease spectrum composition and distribution and disease severity. The development of the fetal is an ongoing process, detection of some structural abnormalities is sometimes linked to which might be related to the natural progression of diseases, some abnormalities may not manifest until the middle or late stages of pregnancy 24 , or even postpartum, such as agenesis of the corpus callosum, arachnoid cyst, hypoplastic vermis, cortical dysplasia, and subependymal cysts. As in Syngelaki's study, more than 90% of the urogenital and reproductive abnormalities in this study were not detected in the first trimester.This study discovered that some structural abnormalities can undergo a series of evolutions during pregnancy. For instance, in a case of type 2 umbilical-portosystemic shunt occurred in the first trimester, the ductus venosus became atretic in the second trimester; one case of a portosystemic shunt with portal hepatic venous communication in the third trimester disappeared in late pregnancy; three cases of foot varus in the first trimester normalized in the second trimester; 13 cases of gallbladder non-display and 34 cases of gallbladder enlargement returned to normal in the third trimester or postpartum period; 6 cases of omphalocele normalized during the second trimester; 2 cases of duodenal obstruction with the "double bubble sign" emerged in the third trimester; 2 cases of aortic coarctation occurred in the second trimester and normalized in the third trimester; one case of pulmonary artery stenosis in the second trimester normalized in the third trimester; one case of myocardial noncompaction displayed characteristic symptoms in the second trimester; and one case of cardiac rhabdomyoma and multiple hyperechoic nodules in the brain appeared in the third trimester. These phenomena are in line with those of relevant reports suggesting that some lesions can evolve and progress during pregnancy 32 . Some structures and hemodynamics exhibit differences during pregnancy and the postpartum period. Multiple objective factors, such as ultrasound scanning level, fetal position, maternal abdominal wall thickness, and amniotic fluid volume, may also result in the misdiagnosis or missed diagnosis of fetal structural abnormalities in the first trimester. In this study, the highest number of missed cases was of structural heart abnormalities. The majority of missed cases were ventricular septal defects (45.7%), slightly lower than that reported by Liao. In our study, the continuous nature of the interventricular septum and transseptal blood flow were routinely observed in multiple planes at each pregnancy stage; however, false-positive and -negative diagnoses were not fully avoided. The second most frequently missed diagnosis was in the limb and skeletal structural abnormalities category (clubfoot and talipes; 58.5%), comparable to that reported by Liao. All cases of polydactyly/syndactyly were missed, mainly because, in this study, finger and toe shapes were observed, but their exact numbers were not counted because finger and toe examinations are frequently challenging to conduct, even at experienced prenatal diagnostic centers, and the overall sensitivity is merely 31% 33 . The number of misdiagnosed abnormal cases in the face and head ranked third (74.7%), marginally lower than the rate reported by Liao. The vast majority of the misdiagnosed cases were ear deformities: auricular deformity in eight, preauricular fistula in two, accessory auricle in two, external auditory canal atresia in one, preauricular skin tags in one. Making the prenatal diagnosis of external ear malformations is challenging for several reasons: the fetal auricle is small and cannot be clearly visualized when close to the uterine wall or located in the far field, while external auditory canal atresia and preauricular fistula are usually undetectable or extremely difficult to detect by prenatal ultrasound. Two recent studies 34 , 35 reported that screening of the tympanic ring aids the detection of external auditory canal atresia. Learning and training are anticipated to enhance the awareness of fetal facial structural abnormalities and gradually increase its detection sensitivity. The absence of abnormalities on a prenatal ultrasound examination at any time does not eliminate the possibility of subsequent abnormalities 36 , Thus,the attention should be paid to the sequential examination and follow-up management of fetal ultrasound findings to maximize the diagnostic accuracy of fetal structural abnormalities during the first trimester. By doing so, clinicians can detect structural abnormalities in a timely manner, reduce missed diagnoses and misdiagnoses, and simultaneously provide professional, accurate, and timely diagnosis and treatment consultations to the families of affected children. Conclusion Our study underscores the significant diagnostic value of systematic ultrasound screening during pregnancy, particularly for severe and lethal fetal structural abnormalities. Identifying subtle and hard-to-detect abnormalities in the first trimester poses substantial challenges. Therefore, our findings highlight the need for a combined approach in screening methodologies to enhance early detection and improve pregnancy outcomes.

The combined use of first- and second-trimester ultrasound screenings can effectively increase the sensitivity of fetal structural abnormality detection, particularly of the urogenital system, gastrointestinal tract, and thoracic and lung-related structural abnormalities, which have an extremely low sensitivity during the first trimester.\u003c/p\u003e \u003cp\u003eIn this study, 69.1% of the severe abnormalities were identified during the first trimester, a proportion similar to which Saltvedt et al.\u003csup\u003e\u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e\u003c/sup\u003e reported that 69% of fatal lethal malformations can be detected during the 12\u0026ndash;14 weeks' gestation.Syngelaki et al.\u003csup\u003e\u003cspan citationid=\"CR27\" class=\"CitationRef\"\u003e27\u003c/span\u003e,\u003cspan citationid=\"CR28\" class=\"CitationRef\"\u003e28\u003c/span\u003e\u003c/sup\u003e stated that the first-semester sensitivity for the detection of anencephaly, exencephaly, holoprosencephaly, gastroschisis, pentalogy of Cantrell, megacystis, and body stalk anomaly can reach 100%. In addition to the abnormalities mentioned above, this includes atrial septal defect, mitral valve atresia, hypoplastic left heart syndrome, hypoplastic right heart syndrome, aortic atresia, cloacal malformation, absence of the radius and ulna, and Meckel\u0026ndash;Gruber syndrome. The sensitivity for the detection of structural abnormalities in the fetal anterior abdominal wall abnormalities, syndromes, and edema/serous cavity effusion during the first trimester exceeds 80%. This study revealed that anterior abdominal wall abnormalities had the highest detection sensitivity during the first trimester similar to that (95.6%) reported by Macedo\u003csup\u003e\u003cspan citationid=\"CR29\" class=\"CitationRef\"\u003e29\u003c/span\u003e\u003c/sup\u003e, which corroborates the perspective that, large abdominal wall defects are often observed during the first trimester. Most of these structural abnormalities can be detected during early pregnancy and should be a key focus of first-trimester screenings.\u003c/p\u003e \u003cp\u003eWe identified all serious malformations in the nervous system, including anencephaly, holoprosencephaly, and exencephaly, in the first trimester as reported by Hu et al.\u003csup\u003e\u003cspan citationid=\"CR27\" class=\"CitationRef\"\u003e27\u003c/span\u003e,\u003cspan citationid=\"CR30\" class=\"CitationRef\"\u003e30\u003c/span\u003e\u003c/sup\u003e. However, the sensitivity of the detection of spina bifida, agenesis of the corpus callosum, and Blake\u0026rsquo;s pouch cyst differ markedly; in fact, we did not uncover any instances of cerebellar dysplasia, the vein of Galen aneurysmal malformation, microcephaly, intracranial infection, or cyst of the septum pellucidum. This might be associated with operator proficiency level, physician comprehension of the disease, and the disease spectrum. The sensitivity for detecting fetal thoracic and lung-related structural abnormalities in the first trimester was the lowest among all systematic structural abnormalities, lower than the 9.7% and 18.4% reported by Liao\u003csup\u003e\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e\u003c/sup\u003e and Syngelaki\u003csup\u003e\u003cspan citationid=\"CR28\" class=\"CitationRef\"\u003e28\u003c/span\u003e,,\u003cspan citationid=\"CR31\" class=\"CitationRef\"\u003e31\u003c/span\u003e\u003c/sup\u003e, respectively, the main reason may be that no diaphragmatic hernias were identified in the first trimester in our study. The diagnosis of diaphragmatic hernia in the first trimester depends on its size and degree of fetal intra-abdominal pressure\u003csup\u003e\u003cspan citationid=\"CR24\" class=\"CitationRef\"\u003e24\u003c/span\u003e\u003c/sup\u003e. Our study incorporated ventricular septal defect, persistent left superior vena cava, and aberrant right subclavian artery, which led to relatively low sensitivity for the detection of cardiac structural abnormalities in the first trimester. If these diseases are excluded, the sensitivity for detecting cardiac structural abnormalities in the first trimester can increase to 50.8%, consistent with the findings of Liao. In the first trimester, our study found a marginally higher detection rate of severe limb malformations than that reported by Syngelaki, a slightly higher detection rate of spinal malformations than that reported by Fong\u003csup\u003e\u003cspan citationid=\"CR31\" class=\"CitationRef\"\u003e31\u003c/span\u003e\u003c/sup\u003e, and a lower sensitivity for the detection of limb-shortening deformities than that reported by Liao. These phenomena might be related to the fact that, in our study, we merely observed the fetal limbs for morphological changes during early pregnancy and did not measure femoral and humeral lengths. It might also be associated with disease spectrum composition and distribution and disease severity.\u003c/p\u003e \u003cp\u003eThe development of the fetal is an ongoing process, detection of some structural abnormalities is sometimes linked to which might be related to the natural progression of diseases, some abnormalities may not manifest until the middle or late stages of pregnancy\u003csup\u003e\u003cspan citationid=\"CR24\" class=\"CitationRef\"\u003e24\u003c/span\u003e\u003c/sup\u003e, or even postpartum, such as agenesis of the corpus callosum, arachnoid cyst, hypoplastic vermis, cortical dysplasia, and subependymal cysts. As in Syngelaki's study, more than 90% of the urogenital and reproductive abnormalities in this study were not detected in the first trimester.This study discovered that some structural abnormalities can undergo a series of evolutions during pregnancy. For instance, in a case of type 2 umbilical-portosystemic shunt occurred in the first trimester, the ductus venosus became atretic in the second trimester; one case of a portosystemic shunt with portal hepatic venous communication in the third trimester disappeared in late pregnancy; three cases of foot varus in the first trimester normalized in the second trimester; 13 cases of gallbladder non-display and 34 cases of gallbladder enlargement returned to normal in the third trimester or postpartum period; 6 cases of omphalocele normalized during the second trimester; 2 cases of duodenal obstruction with the \"double bubble sign\" emerged in the third trimester; 2 cases of aortic coarctation occurred in the second trimester and normalized in the third trimester; one case of pulmonary artery stenosis in the second trimester normalized in the third trimester; one case of myocardial noncompaction displayed characteristic symptoms in the second trimester; and one case of cardiac rhabdomyoma and multiple hyperechoic nodules in the brain appeared in the third trimester. These phenomena are in line with those of relevant reports suggesting that some lesions can evolve and progress during pregnancy\u003csup\u003e\u003cspan citationid=\"CR32\" class=\"CitationRef\"\u003e32\u003c/span\u003e\u003c/sup\u003e.\u003c/p\u003e \u003cp\u003eSome structures and hemodynamics exhibit differences during pregnancy and the postpartum period. Multiple objective factors, such as ultrasound scanning level, fetal position, maternal abdominal wall thickness, and amniotic fluid volume, may also result in the misdiagnosis or missed diagnosis of fetal structural abnormalities in the first trimester. In this study, the highest number of missed cases was of structural heart abnormalities. The majority of missed cases were ventricular septal defects (45.7%), slightly lower than that reported by Liao. In our study, the continuous nature of the interventricular septum and transseptal blood flow were routinely observed in multiple planes at each pregnancy stage; however, false-positive and -negative diagnoses were not fully avoided. The second most frequently missed diagnosis was in the limb and skeletal structural abnormalities category (clubfoot and talipes; 58.5%), comparable to that reported by Liao. All cases of polydactyly/syndactyly were missed, mainly because, in this study, finger and toe shapes were observed, but their exact numbers were not counted because finger and toe examinations are frequently challenging to conduct, even at experienced prenatal diagnostic centers, and the overall sensitivity is merely 31%\u003csup\u003e33\u003c/sup\u003e. The number of misdiagnosed abnormal cases in the face and head ranked third (74.7%), marginally lower than the rate reported by Liao. The vast majority of the misdiagnosed cases were ear deformities: auricular deformity in eight, preauricular fistula in two, accessory auricle in two, external auditory canal atresia in one, preauricular skin tags in one. Making the prenatal diagnosis of external ear malformations is challenging for several reasons: the fetal auricle is small and cannot be clearly visualized when close to the uterine wall or located in the far field, while external auditory canal atresia and preauricular fistula are usually undetectable or extremely difficult to detect by prenatal ultrasound. Two recent studies\u003csup\u003e\u003cspan citationid=\"CR34\" class=\"CitationRef\"\u003e34\u003c/span\u003e,\u003cspan citationid=\"CR35\" class=\"CitationRef\"\u003e35\u003c/span\u003e\u003c/sup\u003e reported that screening of the tympanic ring aids the detection of external auditory canal atresia. Learning and training are anticipated to enhance the awareness of fetal facial structural abnormalities and gradually increase its detection sensitivity.\u003c/p\u003e \u003cp\u003eThe absence of abnormalities on a prenatal ultrasound examination at any time does not eliminate the possibility of subsequent abnormalities\u003csup\u003e\u003cspan citationid=\"CR36\" class=\"CitationRef\"\u003e36\u003c/span\u003e\u003c/sup\u003e, Thus,the attention should be paid to the sequential examination and follow-up management of fetal ultrasound findings to maximize the diagnostic accuracy of fetal structural abnormalities during the first trimester.

This study aimed to ascertain the efficacy of systematic ultrasound screening for fetal structural abnormalities.\u003c/p\u003e\u003ch2\u003eMethod\u003c/h2\u003e \u003cp\u003eThis retrospective analysis examined the results of first-trimester systematic ultrasound screenings performed of 30,336 fetuses between June 2019 to and 2022 and compared them with second- and third-trimester ultrasound screening, postpartum examination, and post-mortem examination results.\u003c/p\u003e\u003ch2\u003eResults\u003c/h2\u003e \u003cp\u003eAmong the 30,336 fetuses, 4.1% (1,240) had structural abnormalities, of which 37.1% (460/1,240) were severe. Overall, 32.2% (399/1,240) of the structural abnormalities were detected via the systematic ultrasound screening, among which 79.7% (318/399) were severe. Of the 318 fetuses with severe abnormalities, 69.1% (220) featured nuchal translucency (NT); 21.1% (220/1,240) of the fetuses with structural abnormalities presented with increased NT versus 46.1% of those with severe structural abnormalities. Of the structural abnormalities detected by the systematic ultrasound screening, 54.6% featured increased NT. Systematic ultrasound screening had a sensitivity of 32.2% and specificity of 99.82% for the identification of fetal structural abnormalities. Areas by sensitivity level were as follows: \u0026ge;80%, anterior abdominal wall abnormalities, syndromes, edema/coelomic hydrops; 50\u0026ndash;80%, nervous system structural abnormalities; 30\u0026ndash;50%, other abnormalities and limb and skeleton structural abnormalities; and \u0026lt;\u0026thinsp;30%, congenital heart defects and facial, gastrointestinal tract, urogenital system, and thoracic and lung-related structural abnormalities.
