Objective To measure condition‐specific detection rates for 14 physical conditions screened for by the NHS fetal anomaly screening programme (FASP) fetal anomaly (FA) ultrasound scan. Design Retrospective audit of 12 694 diagnoses across a 3‐year national cohort. Setting All English NHS and crown‐dependency hospital trusts providing maternity services. Population Pregnancies booked for maternity services with an expected date of delivery between 1 April 2017 and 31 March 2020 and at least one diagnosis of a condition screened for by FASP. Methods Active multi‐source ascertainment, linkage, audit and validation of clinical information to identify the subset of diagnoses meeting the condition‐specific positivity threshold for the FA scan. Main outcome measure The accuracy of the FA scan compared with diagnostic reference standards. Results FA scan detection rates were: anencephaly 96.3% (95% confidence interval [CI] 81.7–99.3%), atrioventricular septal defect: 69.2% (95% CI 65.8–72.4%), bilateral renal agenesis: 98.7% (95% CI 95.4–99.6%), cleft lip: 89.5% (95% CI 87.8–90.9%), congenital diaphragmatic hernia: 60.8% (95% CI 56.5–65%), Edwards syndrome: 73.8% (95% CI 67.5–79.3%), exomphalos: 59.4% (95% CI 49.4–68.7%), gastroschisis: 88.6% (95% CI 79–94.1%), hypoplastic left heart syndrome: 92.7% (95% CI 90–94.8%), lethal skeletal dysplasia: 93.2% (95% CI 88.6–96%), Patau syndrome: 82.3% (95% CI 72.4–89.1%), spina bifida: 93.8% (95% CI 91.8–95.3%), tetralogy of Fallot: 75.4% (95% CI 72.1–78.4%) and transposition of the great arteries: 84.9% (95% CI 81.7–87.5%). Conclusions The performance of the FA scan is above the expectations set in 2010 for most conditions. For the remaining conditions, the majority of fetuses and babies affected are detected before the FA scan.

Information regarding specific anatomic anomalies affords the physician the opportunity to offer the patient sophisticated prenatal procedures, such as fetal surgery or selective fetal reduction in multiple gestations. Likewise, prenatal knowledge about genetic, physiologic, and/or anatomic abnormalities enables the physician to tailor or manage the timing and mode of delivery for optimal maternal and fetal outcomes. Prenatal diagnosis also allows the neonatal and paediatric specialists to be adequately prepared for a potentially ill neonate at delivery. Recent progress in the fields of maternal fetal medicine, radiology, and genetics has resulted in great advances in prenatal diagnosis. Ultrasonography is the initial modality for evaluation of pregnant patient because of its widespread availability and reasonable cost, with other modalities used only if Ultrasonography results are non diagnostic. Hence based on above data the present study was planned Study of Congenital Fetal anomalies with the Help of Sonographic Evaluation. The present study was planned in Department of Radio- Diagnosis, Katihar Medical College and Hospital, Katihar, Bihar, India. All pregnant females of second trimester who are referred from obstetrics and gynaecology department and thus sent to department of Radio diagnosis for antenatal Sonographic examination. A complete antenatal ultrasound examination of pregnant women included in the study will be done using gray scale & colour duplex examination. Obstetric ultrasonography has become an important part of routine antenatal care. Routine anomaly screening improves perinatal outcome directly through termination of pregnancy for certain anomalies. Congenital fetal anomalies are one of the most threatening complications which are prevalent in the society associated with severe morbidity and mortality in the new born fetus or neonates. Ultrasound is the best possible non-invasive technique available to detect any congenital anomalies in pregnant women which will help to identify the severity of the disease, its outcome leading to pregnancy termination or gives an opportunity for fetal therapy or better neonatal care. Keywords: Congenital Fetal anomalies, Sonography, etc.

“…Measurement of the head circumference, abdominal circumference and femur length are required so that fetal growth can be assessed. Chudleigh et al 25 describe in detail the base menu of the 18-20 week anomaly scan. Any significant findings are reported by the ultrasonographer and followed up by a further scan.…”

Congenital malformations are common, occurring in around 1 in 40 pregnancies. Analysis of data from European population-based congenital anomaly registers reported a malformation rate of 29.3 per 1000 births. Eighty percent of these were in live births whereas 17% were observed in fetuses terminated after ultrasound diagnosis of fetal abnormality. The remainder were stillborn or fetal deaths in utero. Fetal autopsy is still regarded as the gold standard procedure for identification of fetal abnormalities but assessment of the fetus by a clinical geneticist or other specialist with expertise in dysmorphology may also be informative. When coupled with other investigations which are non-invasive or involve only sampling of blood or other body fluids, examination for external malformations and dysmorphic features may complement autopsy findings or provide important information as to the causation of fetal abnormalities when autopsy is not possible. This situation is now becoming more common as rates of fetal autopsy have dropped significantly in the UK in recent years.
