Sirenomelia: An anatomical assessment and genetic sex determination of two cases.

The etiology of sirenomelia is currently unknown. Data are limited in comparing external and internal abnormalities using modern imaging technologies and molecular genetic analysis. The purpose of the current study was designed to compare external and internal anatomical defects in two cases of sirenomelia and Potter's sequence. Considered rare, Potter's sequence is a fetal disorder with characteristic features of bilateral renal agenesis, obstructive uropathy, atypical facial appearance, and limb malformations. The internal and external malformations of two term fetuses with sirenomelia and Potter's sequence were compared using assessment of external features, radiography and MRI on internal structures, and molecular genetic studies on sex determination. Data reveal that both fetuses were male and manifested with an overlapping but distinct spectrum of abnormalities. Principal differences were noted in the development of the ears, brain, urogenital system, lower limbs, pelvis, and vertebral column. Defects of the axial mesoderm are likely to underlie the abnormalities seen in both fetuses. The first one, which had only caudal defects, was found to have a spectrum of abnormalities most similar to those associated with more severe forms of the small pelvic outlet syndrome, although the structure and orientation of the sacrum and iliae were different from previously reported cases. The other had both caudal and cranial defects, and was most similar to those described in the axial mesodermal dysplasia syndrome. Defects associated with sirenomelia can be evaluated with standard gross anatomy examination, radiology, MRI, and modified PCR techniques to determine anatomical abnormalities and the sex of preserved specimens, respectively. Evidence indicated that sirenomelia could be developed via various etiologies.

Prenatal diagnosis in the fetal hyperechogenic kidneys: assessment using chromosomal microarray analysis and exome sequencing.

Fetal hyperechogenic kidneys (HEK) is etiologically a heterogeneous disorder. The aim of this study was to identify the genetic causes of HEK using prenatal chromosomal microarray analysis (CMA) and exome sequencing (ES). From June 2014 to September 2022, we identified 92 HEK fetuses detected by ultrasound. We reviewed and documented other ultrasound anomalies, microscopic and submicroscopic chromosomal abnormalities, and single gene disorders. We also analyzed the diagnostic yield of CMA and ES and the clinical impact the diagnosis had on pregnancy management. In our cohort, CMA detected 27 pathogenic copy number variations (CNVs) in 25 (25/92, 27.2%) fetuses, with the most common CNV being 17q12 microdeletion syndrome. Among the 26 fetuses who underwent further ES testing, we identified 7 pathogenic/likely pathogenic variants and 8 variants of uncertain significance in 9 genes in 12 fetuses. Four novel variants were first reported herein, expanding the mutational spectra for HEK-related genes. Following counseling, 52 families chose to continue the pregnancy, and in 23 of them, postnatal ultrasound showed no detectable renal abnormalities. Of these 23 cases, 15 had isolated HEK on prenatal ultrasound. Taken together, our study showed a high rate of detectable genetic etiologies in cases with fetal HEK at the levels of chromosomal (aneuploidy), sub-chromosomal (microdeletions/microduplications), and single gene (point mutations). Therefore, we speculate that combined CMA and ES testing for fetal HEK is feasible and has good clinical utility. When no genetic abnormalities are identified, the findings can be transient, especially in the isolated HEK group.

Evaluation of Pulmonary Hypoplasia in Various Congenital Anomalies with a Comparison of Two Conventional Methods of Assessment: Radial Alveolar Count (RAC) and Lung Weight: Body Weight Ratio (LBW).

OBJECTIVE: Pulmonary hypoplasia is common in the perinatal period and causes death in newborn infants. It is commonly associated with a number of malformation syndromes. Various parameters are used to estimate pulmonary hypoplasia at fetal autopsy including Lung Weight Body Weight ratio (LW:BW), Radial Alveolar Count (RAC) and DNA estimation. MATERIAL AND METHOD: This study was carried out as a retrospective analysis of 108 lung specimens of fetuses with congenital anomalies for a period of five years. All terminated fetuses with anomalies were received with 10% formalin. An inverted Y-shaped incision was made on the fetus to remove the lungs. Lung weight and body weight were measured and the ratio was calculated. Morphometric estimation of RAC was done microscopically by counting the number of alveoli using the Q capture software. RAC was calculated based on gestational age. RESULTS: Among the restrictive lung diseases, pulmonary hypoplasia by the LW:BW ratio was prevalent in 43% while the same by RAC was 19%. Similarly, pulmonary hypoplasia by the LW:BW ratio was prevalent in 35% while the same by RAC was 26% among cases with non restrictive lung diseases. Oligohydramnios showed the highest prevalence of pulmonary hypoplasia (23.7%), followed by renal anomalies (16.9%) and CNS anomalies (15.2%). CONCLUSION: Pulmonary hypoplasia is a common occurrence in many congenital anomalies, premature rupture of membranes, and hydrops fetalis. Identifying the anomaly during the intrauterine period will help to anticipate and accordingly manage the baby in the postpartum period. Early diagnosis of correctable condition like oligohydramnios will also help in the early intervention and prevention of pulmonary hypoplasia.

A qualitative study exploring the needs related to the health system in women with experience of pregnancy termination due to fetal anomalies in Iran.

BACKGROUND: In order to provide appropriate and adequate care to women who have experienced termination of pregnancy due to fetal anomalies, the health needs of this group should be assessed. Considering the lack of information about the care and services required by these women in Iran, this study was conducted with the aim of exploring the needs related to the health system in women with experience of pregnancy termination due to fetal anomalies. METHODS: This study was conducted with a qualitative approach. 40 participants were selected through purposive sampling, and the data were collected through in-depth semi structured interviews and field notes, and analyzed using conventional qualitative content analysis. RESULTS: After analyzing the texts, the needs related to the health system in women with experience of pregnancy termination due to fetal anomalies were categorized in the three main categories: "efficient treatment team", "optimal organizational structure in providing services" and "financial support for families". CONCLUSIONS: The findings of the present study by exploring and highlighting the needs related to the health system in different dimensions in women with experience of pregnancy termination due to fetal anomalies can be helpful for designing and providing basic and comprehensive care programs.

Analysis of the cost effectiveness of different strategies for the antenatal diagnosis of chromosomal aberrations in cases of ultrasound-identified fetal abnormalities.

OBJECTIVE: Principal objective of this work was to analyse the cost effectiveness of different sequences of cytogenetic techniques from the hospital's point of view, after prenatal ultrasound has identified fetal malformations. METHODS: Cytogenetic tests were performed for each case in 3 strategies, and their results are reported and compared to one reference strategy. Two new simulated strategies were considered: chromosomal microarrays alone and a direct test + CMA. MAIN OUTCOMES MEASURES: cost-effectiveness ratio. RESULTS: A single test result was positive in 234 of the 835 pregnancies studied (28%). CMA alone would have identified 239 abnormalities. In the simulated direct test + CMA sequence, the direct test alone would have been positive for 66.1% of the abnormalities identified. When testing was indicated for NT, reference strategy (Direct + karyotyping) costs 1 084.8 euros by positive test results. Strategies Direct + CMA and CMA alone cost respectively 992.7 and 550.0 euros by positive test results. For OUM indications, reference strategy costs 2 937.8 euros by positive test results. Strategies Direct + CMA and CMA alone cost respectively, 2 118.4 and 1 304.7 euros by positive test results. CONCLUSIONS: CMA appears to be the most effective test for prenatal cytogenetic diagnosis of fetal abnormalities identified by ultrasound.

Early alterations in cortical and cerebellar regional brain growth in Down Syndrome: An in vivo fetal and neonatal MRI assessment.

Down Syndrome (DS) is the most frequent genetic cause of intellectual disability with a wide spectrum of neurodevelopmental outcomes. At present, the relationship between structural brain morphology and the spectrum of cognitive phenotypes in DS, is not well understood. This study aimed to quantify the development of the fetal and neonatal brain in DS participants, with and without a congenital cardiac defect compared with a control population using dedicated, optimised and motion-corrected in vivo magnetic resonance imaging (MRI). We detected deviations in development and altered regional brain growth in the fetus with DS from 21 weeks' gestation, when compared to age-matched controls. Reduced cerebellar volume was apparent in the second trimester with significant alteration in cortical growth becoming evident during the third trimester. Developmental abnormalities in the cortex and cerebellum are likely substrates for later neurocognitive impairment, and ongoing studies will allow us to confirm the role of antenatal MRI as an early biomarker for subsequent cognitive ability in DS. In the era of rapidly developing technologies, we believe that the results of this study will assist counselling for prospective parents.

MRI in the diagnosis of fetal developmental brain abnormalities: the MERIDIAN diagnostic accuracy study.

BACKGROUND: Ultrasonography has been the mainstay of antenatal screening programmes in the UK for many years. Technical factors and physical limitations may result in suboptimal images that can lead to incorrect diagnoses and inaccurate counselling and prognostic information being given to parents. Previous studies suggest that the addition of in utero magnetic resonance imaging (iuMRI) may improve diagnostic accuracy for fetal brain abnormalities. These studies have limitations, including a lack of an outcome reference diagnosis (ORD), which means that improvements could not be assessed accurately. OBJECTIVES: To assess the diagnostic impact, acceptability and cost consequence of iuMRI among fetuses with a suspected fetal brain abnormality. DESIGN: A pragmatic, prospective, multicentre, cohort study with a health economics analysis and a sociological substudy. SETTING: Sixteen UK fetal medicine centres. PARTICIPANTS: Pregnant women aged ≥ 16 years carrying a fetus (at least 18 weeks' gestation) with a suspected brain abnormality detected on ultrasonography. INTERVENTIONS: Participants underwent iuMRI and the findings were reported to their referring fetal medicine clinician. MAIN OUTCOME MEASURES: Pregnancy outcome was followed up and an ORD from postnatal imaging or postmortem autopsy/imaging collected when available. Developmental data from the Bayley Scales of Infant Development and questionnaires were collected from the surviving infants aged 2-3 years. Data on the management of the pregnancy before and after the iuMRI were collected to inform the economic evaluation. Two surveys collected data on patient acceptability of iuMRI and qualitative interviews with participants and health professionals were undertaken. RESULTS: The primary analysis consisted of 570 fetuses. The absolute diagnostic accuracies of ultrasonography and iuMRI were 68% and 93%, respectively [a difference of 25%, 95% confidence interval (CI) 21% to 29%]. The difference between ultrasonography and iuMRI increased with gestational age. In the 18-23 weeks group, the figures were 70% for ultrasonography and 92% for iuMRI (difference of 23%, 95% CI 18% to 27%); in the ≥ 24 weeks group, the figures were 65% for ultrasonography and 94% for iuMRI (difference of 29%, 95% CI 23% to 36%). Patient acceptability was high, with at least 95% of respondents stating that they would have iuMRI again in a similar situation. Health professional interviews suggested that iuMRI was acceptable to clinicians and that iuMRI was useful as an adjunct to ultrasonography, but not as a replacement. Across a range of scenarios, iuMRI resulted in additional costs compared with ultrasonography alone. The additional cost was consistently < £600 per patient and the cost per management decision appropriately changed was always < £3000. There is potential for reporting bias from the referring clinicians on the diagnostic and prognostic outcomes. Lower than anticipated follow-up rates at 3 years of age were observed. CONCLUSIONS: iuMRI as an adjunct to ultrasonography significantly improves the diagnostic accuracy and confidence for the detection of fetal brain abnormalities. An evaluation of the use of iuMRI for cases of isolated microcephaly and the diagnosis of fetal spine abnormalities is recommended. Longer-term follow-up studies of children diagnosed with fetal brain abnormalities are required to fully assess the functional significance of the diagnoses.

Ultrasonography is routine in pregnancy to check that the baby's brain is developing as expected. However, no medical test is perfect and ultrasonography may miss some brain abnormalities, may get some brain abnormalities wrong or may diagnose an abnormality that is not really present. Magnetic resonance imaging (MRI) may help clarify difficult cases during pregnancy. We wanted to find out if MRI was better than ultrasonography alone in making an accurate diagnosis. We recruited pregnant women whose ultrasound scan, performed by an expert, suggested that their baby had a brain abnormality, and referred them for a MRI scan. The results of the two tests were compared with each other and to the final outcome of the pregnancy. Our results showed that using MRI in addition to ultrasonography improved the accuracy of the diagnosis in about one in four pregnancies. It changed the prediction of how the baby would develop in at least one in five cases. In many cases, the pregnancy was managed differently because of the MRI result. The MRI was acceptable to women, with 95% saying that they would have MRI again in a similar situation. Neither MRI nor ultrasonography accurately identified children who went on to have delayed development at the age of 2­3 years, but MRI was better than ultrasonography at ruling out developmental problems at this age. The MRI cost more than ultrasonography alone; therefore, whether or not it is worthwhile depends on the value placed on the decisions that changed as a result of its use.

An osteological assessment of cyclopia by micro-CT scanning.

PURPOSE: Imaging modalities such as micro-CT scanning and three-dimensional reconstruction are providing a mechanism for detailed analysis of skeletal components not only of normal specimens but also through revisitation of the abnormal. The aim of this study was to analyse the craniofacial skeleton of five human fetuses with cyclopia by means of micro-CT scanning and three-dimensional reconstruction. MATERIALS AND METHODS: The study consisted of five cyclopean individuals from the paediatric collection of the School of Anatomical Sciences, University of the Witwatersrand. The specimens ranged in age from 22 to 42 weeks of gestation. The osteological features of each bone of the skull were analysed with the aid of micro-CT scanning and analysis using VG studiomax software. RESULTS: A detailed analysis of all the bones of the skull revealed that the upper two-thirds of the viscerocranium and the anterior region of the basicranium were the most affected regions of the cyclopean fetuses. The ethmoid, nasal, inferior concha and the lacrimal bones were absent in all the cases of cyclopia. Major abnormalities were found in the premaxillary region which affected the development of the anterior dentition. CONCLUSION: This study supports the suggestion that the malformations of the visceral bones are secondary to defective development of the presphenoid and mesethmoid cartilages. The ethmoidal bones are important midline struts during normal development and their absence in cyclopia leads to non-laterality of facial features.

Assessment of Gross Fetal Malformations: The Modernized Wilson Technique and Skeletal Staining.

Teratology is the study of anatomical and physiological abnormalities, commonly known as birth defects. If an embryo is exposed to a harmful substance, or teratogen, during the critical period of development, an ensuing malformation may occur. These malformations and their associated mechanisms are studied and analyzed in laboratory animals in order to prevent them from occurring in humans. Rodents such as rats and mice have commonly been used in such studies because of their similarity to humans. In 1959, James G. Wilson designed, developed, and tested a protocol on how to observe and analyze structural malformations in rodent fetuses, which included: external examination, skeletal evaluation, soft tissue analysis, and data collection/analysis. For standardization purposes, i.e., to normalize findings from one lab to another, it is important that this protocol be followed with precision. Although many years have passed since Wilson initially created this protocol, it is still widely used to this day, and only minor changes have been made to his instructions such as the chemical reagents used in the experiments and methods of analysis of the experimental data. Such testing has resulted in major advances in the dissemination of teratology information, including the identification of an increasing number of teratogens and the understanding of the pathogenesis of birth defects. While mechanistically birth defect prevention will include the understanding of individual genomes and pharmacogenomics, overall, morphological assessment will still be required as an integral part of birth defects research. As the interaction between teratogenic and genetic factors is better understood, it is anticipated that the incidence of most types of defects will substantially be reduced.

Just choice: a Danielsian analysis of the aims and scope of prenatal screening for fetal abnormalities.

Developments in Non-Invasive Prenatal Testing (NIPT) and cell-free fetal DNA analysis raise the possibility that antenatal services may soon be able to support couples in non-invasively testing for, and diagnosing, an unprecedented range of genetic disorders and traits coded within their unborn child's genome. Inevitably, this has prompted debate within the bioethics literature about what screening options should be offered to couples for the purpose of reproductive choice. In relation to this problem, the European Society of Human Genetics (ESHG) and American Society of Human Genetics (ASHG) tentatively recommend that any expansion of this type of screening, as facilitated by NIPT, should be limited to serious congenital and childhood disorders. In support of this recommendation, the ESHG and ASHG cite considerations of distribution justice. Notably, however, an account of justice in the organization and provision of this type of screening which might substantiate this recommendation has yet to be developed. This paper attempts to redress this oversight through an investigation of Norman Daniels' theory of Just health: meeting health needs fairly. In line with this aim, the paper examines what special moral importance (for Just health) screening for the purpose of reproductive choice might have where concerning serious congenital and childhood disorders in particular. The paper concludes that screening for reproductive choice where concerning serious congenital and childhood disorders may be important for providing women with fair opportunity to protect their health (by either having or not having an affected child).

Implications of Ohio's 20-Week Abortion Ban on Prenatal Patients and the Assessment of Fetal Anomalies.

Ohio's governor recently signed into law Senate Bill 127, a bill that makes it a fourth-degree felony for a health care provider to perform an abortion "when the probable post-fertilization age of the unborn child is 20 weeks or greater," joining a series of other states that have enacted such legislation or are moving toward similar legislation. Twenty-week bans have salient implications for women's health, quality of care, and access to services, particularly in the context of the delivery of prenatal care. Because of the timeline of the initiation of prenatal care and assessments of fetal genetic and anatomic anomalies, patients may increasingly find themselves at or near the 20-week postfertilization gestational threshold when they have insufficient information to decide about continuing or ending the pregnancy. This law thus leaves women and families with limited time to obtain a genetic or anatomic diagnosis, restricts access to abortion care at a crucial decision-making time in the pregnancy, and has significant implications for the patient-physician relationship. This law also has ramifications for women and health care providers outside of Ohio, because patients who have made the choice to end a pregnancy will have to cross state lines for abortion care. It is important for obstetric providers to be aware of the ramifications of 20-week bans and take steps to ensure that pregnant women receive high-quality care despite the burdens imposed on the health care decision-making process.

The Performance of First-Trimester Anatomy Scan: A Decision Analysis.

Introduction First-trimester ultrasound (US) for anatomy assessment may improve anomaly detection, but it may also increase overall US utilization. We sought to assess the utility of first-trimester US for evaluation of fetal anatomy. Materials and Methods A decision analytic model was created to compare first- plus second-trimester anatomy scans to second-trimester scan alone in four populations: general, normal weight women, obese women, and diabetics. Probability estimates were obtained from the literature. Outcomes considered were number of: major structural anomalies detected, US performed, and false-positive US. Multivariable sensitivity analyses were performed to evaluate the consistency of the model with varying assumptions. Results A strategy of first- plus second-trimester US detected the highest number of anomalies but required more US examinations per anomaly detected. The addition of a first-trimester anatomy US was associated with a small increase in the false-positive US (< 10/10,000). In populations with higher anomaly prevalence and lower second-trimester US sensitivity (i.e., diabetes, obesity), the number of additional US performed per anomaly detected with the first-trimester US was < 60. Discussion In high-risk populations, a first-trimester US in addition to a second-trimester US may be a beneficial approach to detecting anomalies.

Assessment of Placental Stiffness Using Acoustic Radiation Force Impulse Elastography in Pregnant Women with Fetal Anomalies.

OBJECTIVE: We aimed to evaluate placental stiffness measured by acoustic radiation force impulse (ARFI) elastography in pregnant women in the second trimester with a normal fetus versus those with structural anomalies and non-structural findings. MATERIALS AND METHODS: Forty pregnant women carrying a fetus with structural anomalies diagnosed sonographically at 18-28 weeks of gestation comprised the study group. The control group consisted of 34 healthy pregnant women with a sonographically normal fetus at a similar gestational age. Placental shear wave velocity (SWV) was measured by ARFI elastography and compared between the two groups. Structural anomalies and non-structural findings were scored based on sonographic markers. Placental stiffness measurements were compared among fetus anomaly categories. Doppler parameters of umbilical and uterine arteries were compared with placental SWV measurements. RESULTS: All placental SWV measurements, including minimum SWV, maximum SWV, and mean SWV were significantly higher in the study group than the control group ([0.86 ± 0.2, 0.74 ± 0.1; p < 0.001], [1.89 ± 0.7, 1.59 ± 0.5; p = 0.04], and [1.26 ± 0.4, 1.09 ± 0.2; p = 0.01]), respectively. CONCLUSION: Placental stiffness evaluated by ARFI elastography during the second trimester in pregnant women with fetuses with congenital structural anomalies is higher than that of pregnant women with normal fetuses.

'You're looking for different parts in a jigsaw': foetal MRI (magnetic resonance imaging) as an emerging technology in professional practice.

Magnetic resonance imaging (MRI) was first introduced into clinical practice during the 1980s. Originally used as a diagnostic tool to take pictures of the brain, spine, and joints, it is now used to visualise a range of organs and soft tissue around the body. Developments in clinical applications of the technology are rapid and it is often viewed as the 'gold standard' in many areas of medicine. However, most existing sociological work on MRI tends to focus on the profession of radiology, little is known about the impact of MRI on a broader range of clinical practice. This article focuses on MRI use in pregnancy, a relatively new application of the technology. Drawing on empirical research with a range of health professionals (from radiologists to pathologists) in the North of England, this article asks: how do different types of health professionals engage with the technology and to what end? It will argue that MRI use in pregnancy offers an increasingly important piece of the diagnostic jigsaw, often acting as a bridging technology between medical specialties. The implications of this will be explored in the context of broader sociological debates on the 'visualisation' of medicine and its impact on professionals.

Prenatal diagnosis: From policy to practice. Two distinct ways of managing prognostic uncertainty and anticipating disability in Brazil and in France.

Prenatal diagnosis (PND) has gradually established itself as part of the pregnancy monitoring process, with a view to reducing the number of births of children exposed to disability by combining the use of biomedical tools with laws that authorise abortion in cases of foetal pathology. This article looks at how laws which vary from one country to another modulate the way in which PND practices are organised on a daily basis, determine the discourse of practitioners and lead them to adopt specific stances during prenatal consultations with couples coping with a foetal anomaly. We present a comparative ethnographic study, which took place between 2009 and 2011 in France and Brazil, in reference units, based on observation of consultations, professional meetings, and interviews with health practitioners. The fact that access to abortion due to foetal pathology is possible in France, and criminalised in Brazil, conditions how doctors analyse the framework of their medical practice and approach the issue of disability with couples during consultations. In France, practitioners would appear to be satisfied with a professional framework that they themselves created. Faced with prognostic uncertainty, the legal obligation to inform encourages them to discuss all of the potential complications of the diagnosed anomalies and leads them to provide probabilistic information about the life of the child to be, supported by evidence-based medicine. In Brazil, in the public service, the lack of access to abortion has created a malaise among practitioners who criticise this impediment to the objective nature of their practice and to the quality of the information that they provide. Some use prognostic uncertainty to direct the thoughts of women and couples towards the dynamics proper to each individual human trajectory within a given family and a specific social environment.

The reliability of fetal MRI in the assessment of brain malformations.

OBJECTIVES: To assess the inter- and intraobserver reliability of different fetal MRI measurements in cases of fetal brain malformations and to examine the concordance between ultrasonography (US) and MRI findings. METHODS: Fetal brain MRIs and US findings of 56 pregnant women were retrieved from the institutional database. Standardized fetal brain MRI measurements were performed by 4 observers, and the inter- and intraobserver reliability was determined. Additionally, US and MRI findings were retrospectively compared. RESULTS: The interobserver intraclass correlation coefficient (ICC) was above 0.9 for the cerebellum and posterior horn of the lateral ventricle. The measurements regarding the third ventricle (0.50), the fourth ventricle (0.58), and the corpus callosum (0.63) showed poor reliability. Overall, the intraobserver reliability was greater than the interobserver reliability. US and MRI findings were discordant in 29% of the cases with MRI rendering an extended diagnosis in 18%, a change of diagnosis in 3.6%, and excluding pathological findings suspected on US in 7.1%. CONCLUSIONS: Fetal MRI is a valuable complement to US in the investigation of fetal brain malformations. The reliability of most parameters was high, except for the measurements of the third and fourth ventricles and the corpus callosum.

O que os olhos veem, o coração sente: estudo sobre a detecção de malformação fetal na experiência de gestantes na Bahia / What the eyes see, the heart feels: the study fetal malformation detection in the pregnant women's experience in Bahia

Esta tese discute o impacto do Diagnóstico de Malformação fetal na experiência das gestantes usuárias do SUS na Bahia, destacando as noções de dia-gnosis e pro-gnosis desenvolvidas por Gross e Shuval (2008) de forma associada à medicina do risco no encontro médico-paciente. Destaca o discurso biomédico na formatação diagnóstica, as diferentes percepções de risco e o forte engajamento das usuárias frente às tecnologias pré-natais e intervenções cirúrgicas neonatais, caucionado na esperança de que o avanço da ciência seja capaz de reverter ou abrandar a condição do seu feto/bebê. È diante da responsabilização da mulher por não ter produzido um feto/bebê saudável, mas um feto/bebê malformado, que se observa a prevalência de normas culturais e de gênero que conferem à maternidade um lugar de autossacrificio, de dedicação e criação dos filhos, como também status social O espaço pré-natal é marcado pela ausência de discussão a respeito do prognóstico de tais condições, com a consequente busca pelas gestantes do conhecimento por meio da internet, da opinião do marido e da crença religiosa que servem de alicerce para lidar com a antecipação da deficiência. As gestantes acreditam ser este um desígnio de Deus, uma espécie de provação e uma prova de amor incondicional ao futuro filho com deficiência (que poderá ou não sobreviver). A maioria das gestantes, 20 entrevistadas, prefere, contudo, ter um filho com deficiência do que sofrer sua perda. Em outra vertente, a tese analisa a forma como se organiza o sistema de saúde quanto à detecção de uma malformação congênita, apontando a precariedade da rede de atenção básica quanto à qualificação dos profissionais e o devido encaminhamento referente ao serviço especializado. A tecnologia de visualização ­ o ultrassom obstétrico ­ é a primordial ferramenta para detecção de alguma alteração fetal, porém somente ocorre o "esclarecimento" do diagnóstico de malformação fetal no serviço público de referência em medicina fetal em Salvador, Bahia. Destaca-se a falta de uma política pública do Ministério da Saúde que norteie o desenvolvimento da medicina fetal no Brasil, haja vista os diferentes impactos diante das tecnologias de inovação em saúde que geram vulnerabilidades e desigualdades sociais. Enfatiza-se a necessidade de uma revisão quanto à regulamentação do uso do ultrassom obstétrico que impeça o uso abusivo ou sua omissão diante dos crescentes casos de anomalias congênitas
