RESUMO

RATIONALE: During ultrasound prenatal screening, absence of the fetal nasal bone is used as a marker for common aneuploidies in singleton pregnancies. However, its application in multiple pregnancies is less sensitive and more challenging owing to difficulties in obtaining adequate views of the fetal face. PATIENT CONCERNS: A 38-year-old woman with dichorionic-diamniotic (DCDA) pregnancy and a history of in vitro fertilization and embryo transfer was referred to our hospital with the absence of the nasal bone noted on ultrasound images obtained during the second trimester in 1 fetus. DIAGNOSIS: Prenatal sonographic examination revealed the absence of the nasal bone in 1 fetus in the DCDA gestation. Amniocentesis performed on the dual amniotic sacs revealed normal karyotypes for each twin. The absence of the nasal bone was confirmed on a radiograph obtained postnatally in 1 infant. INTERVENTIONS: The mother underwent routine outpatient care according to the gestational age and successfully delivered following lower-segment cesarean section. OUTCOMES: Two live infants were uneventfully delivered. Radiography confirmed the absence of the nasal bone in 1 of the newborns on postnatal day 3. The infants were followed up until 2 years and 9 months of age, which revealed normal appearance and eating and breathing functions. LESSONS: Prenatal diagnosis of the absence of nasal bone in 1 fetus of DCDA pregnancy has rarely been reported. Although a fetus with the absence of the nasal bone in DCDA gestation poses a significant risk of aneuploidy, it is acceptable when the defect is an isolated anomaly after ruling out genetic abnormalities. Appropriate consultation should be provided for these patients.

RESUMO

Objective: To investigate the clinical characteristics and outcomes of monochorionic monoamniotic (MCMA) twin pregnancy. Methods: The clinical data of 60 MCMA twin pregnant women who were terminated in Peking University Third Hospital from January 2011 to December 2019 were collected, and the general clinical data, prenatal examination and pregnancy outcomes were analyzed retrospectively. Results: The age of 60 MCMA twin pregnant women was (31.0±4.1) years old, among which 44 cases were primiparas (73%, 44/60) and 16 cases were multiparas (27%, 16/60). Fifty-eight cases were diagnosed as MCMA twin pregnancy prenatally and were confirmed after delivery. Median ultrasonic diagnosis of gestational age was 12 weeks (range: 8-30 weeks). In the 60 MCMA twin pregnancies, 6 cases were conjoined twins, 5 cases were complicated with twin reversed arterial perfusion sequence (TRAPS), and 10 cases were diagnosed as other fetal malformation by prenatal ultrasound examination. Among the 60 MCMA twin pregnant women, 19 cases had spontaneous abortion or induced abortion due to fetal malformation, fetal death or other reasons within 28 weeks of pregnancy, 41 cases entered the perinatal period, a total of 70 newborns survived. The main cause of perinatal fetal or neonatal death was fetal dysplasia. Conclusions: There is a high incidence of fetal abnormality and perinatal mortality in MCMA twin pregnancy. Accurate early diagnosis, enhanced management and monitoring during pregnancy, and individualized treatment are the keys to improve MCMA twin pregnancy outcomes.

RESUMO

RATIONALE: Rhabdomyoma is the most common type of fetal heart tumors and 50% to 60% of cardiac rhabdomyomas are associated with tuberous sclerosis complex (TSC). TSC is characterized by hamartomas in multiple organ systems including the brain, heart, skin, lungs, and kidneys, resulting in complications such as learning difficulties, epilepsy, behavioral problems, and renal failure. The etiological diagnosis of Rhabdomyoma is very important. PATIENT CONCERNS: A 22-year-old G2P0 woman chose to terminate the pregnancy at 24 + 4 weeks of gestation because of the presence of a cardiac space-occupying lesion in the fetus. DIAGNOSES: The pathological diagnosis of cardiac neoplasm tissue was cardiac rhabdomyoma, but the etiology was unknown. INTERVENTIONS: Targeted exome capture, next-generation sequencing (NGS) and sanger sequencing were performed on peripheral blood lymphocytes and paternal sperm. OUTCOMES: Targeted exome capture sequencing revealed a novel heterozygous variant (NM_000548, c.2294delC) in the tuberous sclerosis 2 (TSC2) gene. Sanger sequencing of maternal blood samples showed no mutation at this locus, however, suspected low level mosaicism was observed in paternal blood samples. Deep NGS analysis showed that about 7% paternal alleles from peripheral blood leucocytes and 20% paternal alleles from sperm carried the mutation consistent with somatic and germinal mosaicism. LESSONS: For fetuses suspected of TSC, when pathogenic mutations are detected in the tuberous sclerosis 1 (TSC1) or TSC2 gene, it is recommended that the parents should be screened by deep NGS and their germ cells are screened as well if necessary, which would help to predict the risk of TSC recurrence in the next pregnancy.

RESUMO

RATIONALE: Apert syndrome (AS) is an autosomal dominant inheritance pattern of the most severe craniosynostosis syndrome. AS is characterized by synostosis of cranial sutures and acrocephaly, including brachycephaly, midfacial hypoplasia, and syndactyly of the hands and feet. Patients with AS often present with craniosynostosis, severe syndactyly, and skin, skeletal, brain, and visceral abnormalities. PATIENT CONCERNS: A pregnant Chinese woman presented with a fetus at 23 + 5 weeks of gestation with suspected AS in a prenatal ultrasound examination. Following ultrasound, the pregnancy underwent spontaneous abortion. Gene sequencing was performed on the back skin of the dead fetus. DIAGNOSIS: The diagnosis of AS was confirmed on the basis of clinical manifestations of the fetus, and a de novo mutation in the fibroblast growth factor receptor 2 (FGFR2) gene was identified. INTERVENTIONS: The couple finally chose to terminate the pregnancy based on the ultrasonic malformations and the risk of the parents having a neonate with AS in the future is small. However, any future pregnancy must be assessed by prenatal diagnosis. OUTCOMES: The dead fetus presented with bilateral skull deformation. Additionally, there were bilateral changes to the temporal bone caused by inwards movement leading to concave morphology, a "clover" sign, and syndactyly from the index finger/second toe to the little finger/little toe. AS was diagnosed by genetic testing, which showed a p.S137W (c.410C>G, chr10:123279677) mutation in the FGFR2 gene. LESSONS: Clinicians should be aware that there are a variety of ultrasound findings for AS. Therefore, genetic testing should be used when appropriate to confirm diagnosis of AS.

RESUMO

BACKGROUND: In low resource settings recall of the date of the mother's last menstrual period may be unreliable and due to limited availability of prenatal ultrasound, gestational age of newborns may not be assessed reliably. Preterm babies are at high risk of morbidity and mortality so an alternative strategy is to identify them soon after birth is needed for early referral and management. OBJECTIVE: The objective of this study was to assess the accuracy in assessing prematurity of newborn, over and above birthweight, using a pictorial Simplified Gestational Age Score adapted for use as a Tablet App. METHODS: Two trained nurse midwives, blinded to each other's assessment and the actual gestational age of the baby used the app to assess gestational age at birth in 3 hospitals based on the following 4 parameters-newborn's posture, skin texture, breast and genital development. Inter-observer variation was evaluated and the optimal scoring cut-off to detect preterm birth was determined. Sensitivity and specificity of gestational age score using the tablet was estimated using combinations of last menstrual period and ultrasound as reference standards to assess preterm birth. The predictive accuracy of the score using the area under a receiver operating characteristic curve was also determined. To account for potential reference standard bias, we also evaluated the score using latent class models. RESULTS: A total of 8,591 live singleton births whose gestational age by last menstrual period and ultrasound was within 1 weeks of each other were enrolled. There was strong agreement between assessors (concordance correlation coefficient 0.77 (95% CI 0.76-0.78) and Fleiss' kappa was 0.76 (95% CI 0.76-0.78). The optimal cut-off for the score to predict preterm was 13. Irrespective of the reference standard, the specificity of the score was 90% and sensitivity varied from 40-50% and the predictive accuracy between 74%-79% for the reference standards. The likelihood ratio of a positive score varied between 3.75-4.88 while the same for a negative likelihood ratio consistently varied between 0.57-0.72. Latent class models showed similar results indicating no reference standard bias. CONCLUSION: Gestational age scores had strong inter-observer agreement, robust prediction of preterm births simplicity of use by nurse midwives and can be a useful tool in resource-limited scenarios. TRIAL REGISTRATION: The Tablet App for the Simplified Gestational Age Score (T-SGAS) study was registered at ClinicalTrials.gov NCT02408783.

RESUMO

OBJECTIVES: To explore the method and significance of prenatal counseling in cardiac surgery for fetal congenital heart disease (CHD). METHODS: The prenatal counseling should be provided by experienced CHD experts. The preliminary clinical diagnosis based on relevant data was carried out, the prognosis risk for fetal CHD was graded, and the pathophysiological process and potential hazards of the disease were analyzed. The current condition of CHD in the treatment plan, the long-term quality of life, and the special requirements of parturition in place, period and mode were described. A reliable follow-up system of the fetuses was established, the diagnosis after delivery was verified, and surgical treatment was carried out timely. RESULTS: From January 2016 to December 2018, 225 parents with fetal CHD received prenatal counseling, including 60 fetuses (26.7%) with simple CHD and 165 (73.3%) with complex CHD, among which 59 cases (98.3%) and 93 cases (56.4%) decided to continue the pregnancy, respectively. During the follow-up, 118 fetuses were born, of which 66 infants received surgical treatment within 6 months after birth, 63 infants (95.5%) recovered and 3 infants (4.5%) died. The rest 52 infants continued to be followed up. CONCLUSIONS: The prenatal counseling for fetal CHD can provide the parents a comprehensive medical information about CHD, which is beneficial to making appropriate pregnancy decisions, and can turn the fetuses from unreasonable birth and passive treatment to selective birth and active treatment in CHD.

RESUMO

Prenatal diagnosed congenital infection by Enterovirus is rarely described in the literature. A few casereports describe severe abnormalities observed by ultrasound that have led to spontaneous intrauterine demise or early death of the newborn. We report the case of a dichorionic diamniotic twin pregnancy. At 24 weeks of gestation, the second trimester ultrasound examination shows cardiac, brain and abdominal abnormalities in one of the fetuses. The other fetus has a normal appearance. "Standard" serological tests conducted on the mother are negative and amniocentesis reveals no genetic abnormality. After birth, Reverse Transcription Polymerase Chain Reaction (PCR) on samples of blood, ascites and stool reveals to be positive for Enterovirus in both newborns. Both are viable and exhibit severe brain abnormalities with severe neurological sequelae such as cerebral palsy, visual and hearing impairment. This case report illustrates the difficulty of prenatal diagnosis of congenital Enterovirus infection and informs about its possible neurological sequelae.

RESUMO

Objective To analyze the efficiency of prenatal ultrasound screening service in Beijing and thus optimize the secondary prevention system for birth defects in Beijing. Methods Data were collected from the prenatal screening work reports of Beijing from 2010-2016.Key variables were extracted after data quality control.Data envelopment analysis was performed to analyze the efficiency and changing trend of ultrasound-based screening service and to compare the service efficiency between urban and suburban areas in Beijing. Results From 2010 to 2016,the technical efficiency of ultrasound screening services showed an increasing trend,and the geometric mean of technical efficiency in suburban areas was higher than that in urban areas.From 2010 to 2016,the total factor productivity of ultrasound screening service increased by 12.3% annually,in which the technical change increased by 12.0% annually;the technical efficiency increased by 0.3%,the pure technical efficiency increased by 13.9% annually,and the scale efficiency decreased by 0.4%.Conclusions The technical efficiency of ultrasound screening service in Beijing increased from 2010 to 2016,and the total factor productivity improved.Technical change and pure technical efficiency change were the main reasons for the improvement.The resource allocation should be further optimized to improve the scale efficiency and enhance the training of prenatal ultrasound screening technicians.

RESUMO

Muscle ultrasound density (MUD) is a non-invasive parameter to indicate neuromuscular integrity in both children and adults. In healthy fetuses and infants, physiologic MUD values during development are still lacking. We therefore aimed to determine the physiologic, age-related MUD trend of biceps, quadriceps, tibialis anterior, hamstrings, gluteal and calf muscles, from pre- to the first year of postnatal life. To avoid a bias by pregnancy-related signal disturbances, we expressed fetal MUD as a ratio against bone ultrasound density. We used the full-term prenatal MUD ratio and the newborn postnatal MUD value as reference points, so that MUD development could be quantified from early pre- into postnatal life. Results: During the prenatal period, the total muscle group revealed a developmental MUD trend concerning a fetal increase in MUD-ratio from the 2nd trimester up to the end of the 3rd trimester [median increase: 27% (range 16-45), p < .001]. After birth, MUD-values increased up to the sixth month [median increase: 11% (range -7-27), p = 0.025] and stabilized thereafter. Additionally, there were also individual MUD characteristics per muscle group and developmental stage, such as relatively low MUD values of fetal hamstrings and high values of the paediatric gluteus muscles. These MUD trends are likely to concur with analogous developmentally, maturation-related alterations in the muscle water to peptide content ratios.

RESUMO

This study aimed to assess agreement between antenatal estimates of gestational age by ultrasound and clinical records at birth in the Brazilian Amazon. Ultrasound examinations were scheduled during the second trimester for 578 pregnant women prospectively screened at primary health care units, following a standardized protocol for image quality control. A multistage algorithm was used to assess the best estimate of gestational age during the antenatal period, considering reliability of last menstrual period (LMP) and acceptable differences in relation to ultrasound estimates derived from fetal biparietal diameter and femur length. Agreement of antenatal estimates of gestational age confirmed by ultrasound and clinical records at birth was analyzed with Bland-Altman plots and kappa coefficients (preterm and postterm births). Overall, ultrasound examinations presented high quality (>90% of satisfactory images), and were adopted as the best estimate of gestational age among 83.4% of pregnant women, confirming reliable LMP in the remaining proportion. On average, difference in gestational age between antenatal estimates and clinical records was 0.43 week (95% CI: 0.32, 0.53). Classification of preterm births had a good agreement (kappa: 0.82, p<0.001), but a poor performance was observed for postterm births (kappa: -0.06, p = 0.92). Higher differences in gestational age were noted for participants with >11 years of education and cases of caesarean deliveries. In conclusion, high-quality ultrasound images from the second trimester of pregnancy based the assessment of gestational age, while reliability of LMP was limited. Information from clinical records at birth presented an acceptable agreement on average and for classification of preterm births, which is relevant for properly interpreting perinatal outcomes. Discrepancies in caesarean deliveries may warrant further investigation.

RESUMO

Many high-risk conditions of pregnancy are undetected until the time of delivery in low-income countries. We developed a point-of-care ultrasound training protocol for providers in rural Uganda to detect fetal distress or demise, malpresentation, multiple gestation, placenta previa, oligohydramnios and preterm delivery. This was a mixed-methods study to evaluate the 2-week training curriculum and trainees' ability to perform a standard scanning protocol and interpret ultrasound images. Surveys to assess provider confidence were administered pre-training, immediately after, and at 3-month follow up. Following lecture and practical demonstrations, each trainee conducted 25 proctored scans and were required to pass an observed structured clinical exam (OSCE). All images produced 8 weeks post course underwent blinded review by two ultrasound experts to assess image quality and to identify common errors. Key informant interviews further assessed perceptions of the training program and utility of point-of-care ultrasound. All interviews were audio recorded, transcribed, and reviewed by multiple readers using a content analysis approach. Twenty-three nurse/nurse midwives and two physicians from one district hospital and three health centers participated in the training curriculum. Confidence levels increased from an average of 1 point pre-course to over 6 points post-course for all measures (maximum of 7 points). Of 25 participants, 22 passed the OSCE on the first attempt (average score 89.4%). Image quality improved over time; the final error rate at week 8 was less than 5%, with an overall kappa of 0.8-1 for all measures between the two reviewers. Among the 12 key informant interviews conducted, key themes included a desire for more hands-on training and longer duration of training and challenges in balancing clinical duties with ability to attend training sessions. This study demonstrates that providers without previous ultrasound experience can detect high-risk conditions during labor with a high rate of quality and accuracy after training.

RESUMO

INTRODUCCIÓN: La hernia de Amyand consiste en la presencia del apéndice cecal en el saco herniario, generalmente en localización derecha, aunque se recogen casos de localización izquierda debido a malrotación intestinal. EXPOSICIÓN DEL CASO: Lactante varón de 3 meses de edad, con onfalocele diagnosticado en la 12ª semana de gestación e intervenido a las 48 horas del nacimiento. Durante el seguimiento se diagnostica de hernia inguinal bilateral, realizando herniotomía bilateral programada. En la intervención se encuentra el apéndice cecal en el saco herniario izquierdo, procediendo a una apendicectomía profiláctica. COMENTARIOS: La incidencia de la hernia de Amyand es del 0,4-1% (3 veces más frecuente en población pediátrica). La localización izquierda suele asociarse a alteraciones en la rotación intestinal. El tratamiento de las hernias de Amyand derechas se recoge en la clasificación de Losanoff-Basson. En las izquierdas, se recomienda realizar apendicectomía profiláctica para evitar confusiones diagnósticas en caso de apendicitis


INTRODUCTION: Amyand's hernia is defined as the presence of the cecal appendix inside the hernia sac. It is usually located on the right side, but left-sided cases due to intestinal malrotation have also been reported. CASE PRESENTATION: 3-month-old male infant diagnosed with omphalocele at the 12th week of gestation undergoing surgery 48 hours post-birth. Bilateral inguinal hernia was diagnosed during follow-up, so scheduled bilateral herniotomy was performed. During surgery, the cecal appendix was identified inside the left herniary sac, so prophylactic appendectomy was carried out. CONCLUSIONS: The incidence of Amyand's hernia ranges from 0.4 to 1% - three times higher in pediatric patients. Left-sided hernias are often associated with intestinal rotation disorders. Treatment of right Amyand's hernia is described in Losanoff-Basson's classification. In left-sided hernias, prophylactic appendectomy is recommended to avoid diagnostic confusion in case of appendicitis

RESUMO

OBJECTIVE: To assess accuracy and reproducibility of MRI diagnosis of invasive placentation (IP) in high-risk patients and to evaluate reliability of MRI features. Secondary aim was to evaluate impact of interventional radiology (IR) on delivery outcomes in patients with IP at MRI. METHODS: 26 patients (mean age 36.24 y/o,SD 6.16) with clinical risk-factors and echographic suspicion of IP underwent 1.5 T-MRI. Two readers reviewed images. Gold-standard was histology in hysterectomised patients and obstetric evaluation at delivery for patients with preserved uterus. Accuracy and reproducibility of MRI findings were calculated. RESULTS: Incidence of IP was 50% (13/26) and of PP was 11.54% (3/26). MRI showed 100% sensitivity (95% CI = 75.3-100%) and 92.3% specificity (95% CI = 64.0-100%) in the diagnosis of IP. Gold-standard was histology in 10 cases and obstetric evaluation in 16. MRI findings with higher sensitivity were placental heterogeneity, uterine bulging and black intraplacental bands. Uterine scarring, placental heterogeneity, myometrial interruption and tenting of the bladder showed better specificity. MRI inter-rater agreement with Cohen's K was 1. 11 patients among 14 with MRI diagnosis of IP received IR assistance with positive impact on delivery outcomes in terms of blood loss, red cells count, intense care unit length of stay, days of hospitalisation and risk of being transfused. CONCLUSION: MRI is an accurate and reproducible technique in prenatal diagnosis of IP. MRI helps planning a safe and appropriate delivery eventually assisted by IR, which positively affects foetal and maternal outcomes. ADVANCES IN KNOWLEDGE: The adoption of MRI evaluation in patients with high risk of invasive placentation allows a more accurate diagnosis in terms of both presence of the disease and its extension to or through or even beyond the myometrium. This led to a better dedicated delivery management with eventual adoption of interventional radiology with a global positive effect on foetal and maternal outcomes.

RESUMO

Los miomas uterinos son una de las patologías ginecológicas más comunes encontrándose hasta en el 70% de las mujeres de raza caucásica y en el 80% de las mujeres de raza negra1,2. En los últimos años, la angiogénesis y la vascularización se han convertido en pieza fundamental de estudio del crecimiento de los tumores. En el caso de los miomas uterinos se ha descubierto que existen diferencias en la vascularización cuando se compara con el tejido uterino adyacente. La patogenia de los miomas es multifactorial existiendo varias vías que intervienen en el crecimiento de los mismos como la vía estrogénica, la progestagénica y la de los factores de crecimiento3. Otra de las vías qué influyen en su desarrollo es la vía de la vitamina D. Niveles inadecuados de dicha vitamina pueden favorecer el crecimiento de los mismos. En nuestro trabajo hemos analizado cómo influye la terapia con vitamina D en el volumen de los miomas y en su vascularización mediante el análisis sérico de VEGF y ecografía 3 DPW


Uterine fibroids are one of the most common gynaecological disorders, being found in 70% of Caucasian women and 80% of Afro-Caribbean women 1,2. In recent years, angiogenesis and vascularisation have become a key part of study of tumour growth. Differences in vascularisation have been discovered in uterine fibroids when compared to adjacent uterine tissue. The pathogenesis of uterine fibroids is multifactorial. Several pathways are involved in their growth have been described, such as the oestrogen pathway, the gestagen pathway, and the pathway of the growth factors. Another of the pathways that influences their development is the vitamin D pathway, as inadequate levels of this vitamin may favour the growth of uterine fibroids3. In this work, an analysis is made on how vitamin D therapy influences the volume and vascularity of uterine fibroids, using serum VEGF levels and 3DPW Ultrasound

RESUMO

Currently available fetal echocardiographic reference values are derived mainly from North American and European population studies, and there is a lack of reference z-score for fetal echocardiographic measurement in Asian populations. The aim of this study was to establish normal ranges of echocardiographic measurements and z-scores in healthy Asian fetuses. A total of 575 healthy pregnant Taiwanese with an estimated gestational age from 14 to 38 weeks were enrolled voluntarily for this observational study. Standard two-dimensional echocardiography was performed to obtain measurements of the cardiac chambers and great arteries of the developing fetuses. In contrast to past studies, our sample was more evenly distributed for estimated gestational age (p<0.001). We present percentile graphs for 13 fetal echocardiographic measurements from the knowledge of estimated gestational age, biparietal distance, head circumference, abdominal circumference, and femur length. Most cardiac structures and developmental markers had linear models as the best-fitting, except for transverse aortic isthmus by estimated gestational age and transverse ductus arteriosus by femur length. Our findings indicate that estimated gestational age was generally the best model for fetal heart development, while head circumferences could be used as an optimal developmental marker to predict left atrium, right atrium, right ventricle, pulmonary annulus, and ductus arteriosus. Lastly, we developed nomograms for each of the 13 fetal heart measurements by each developmental markers. This is the first study providing echocardiographic reference ranges and nomograms for Asian fetuses. Computing z-scores from nomograms helps in standardizing comparisons and adds additional prognostic information to the diagnosis of congenital heart disease.

RESUMO

INTRODUCTION: Subchorionic hematoma (SCH) is a rare type of intrauterine hematoma, usually with limited impact on fetuses and pregnant women. But massive hematoma causes significant space occupying effect, affects blood supply of the fetus and finally may lead to fetus demise. PATIENT CONCERNS: In this case report, we reported a 22-year-old pregnant woman presented to our hospital with complaint of irregular lower abdominal pain. DIAGNOSIS: Ultrasonography and magnetic resonance imaging confirmed an intrauterine mass with a compressed growth-restricted fetus. INTERVENTIONS: The patient underwent diseases induced labor after confirmation of fetus demise by ultrasonography. OUTCOMES: Histopathological examination of the mass revealed a SCH. CONCLUSION: Though small SCH can be found in quite a few pregnant women and is usually harmless, enormous hematoma can result in adverse pregnancy outcomes. It may be difficult, in some cases, to differentiate it from uterine tumors or placental tumors by means of ultrasonography and magnetic resonance imaging, especially when the mass is hyperechoic under ultrasonography. This case report stresses the importance of regular examinations of pregnant women.

RESUMO

Background: An important component of the first-trimester scan is nuchal translucency thickness at 11 weeks to 13 weeks 6 days of gestation. A nuchal translucency ≥3.3 mm is a significant early pregnancy scan finding associated with Trisomies 13, 18, and 21 and congenital heart diseases. Aims: To determine the prevalence and outcome of increased fetal nuchal translucency among pregnant women. Subjects and Methods: A prospective cohort study at the Obstetrics and Gynaecology Department of Usmanu Danfodiyo University Teaching Hospital Sokoto. This was a prospective study of 265 consecutively recruited women in the first trimester of pregnancy who presented to antenatal clinics over a 20-week period. An NT scan was conducted at 11 weeks to 13 weeks 6 days followed by an anomaly scan at 18-22 weeks. Patients were followed up to delivery and 6-week post-partum. The neonates were examined at delivery and at 6-week postnatal life. Data entry and analysis was done with IBM SPSS version 20. The level of significance was set at less than 0.05. Frequency distribution; student t-test and Chi-squared test. Results: The 95th percentile NT was 3.3 mm and the prevalence of increased NT above 3.3 mm was 3%. The mean maternal age of the participants was 28.1 ± 5.1 years and the modal parity was Para 0. The most common anomalies associated with increased NT were ventricular septal defect and spina bifida. A congenital anomaly was significantly associated with increased NT (P < 0.001). Conclusions: The prevalence of increased fetal nuchal translucency is relatively high in our environment and is associated with congenital fetal defects. Routine screening with first-trimester ultrasound will help detect congenital anomalies early.
