In this context, it is suggested that validation of the prenatal diagnosis of congenital anomalies is dependent on the institution studied, the equipment used and, primarily, on the ultrasonographist. Therefore, it was necessary to undertake a study that would determine the validity of prenatal ultrasound diagnosis of fetal anomalies as performed at a specialist fetal medicine center in the State of Pernambuco, Brazil.

This was a cross-sectional observation study to validate a diagnostic test carried out with pregnant women in the high-risk ward at the Instituto de Medicina Integral Professor Fernando Figueira I.

Multiple births, births not taking place at IMIP and cases where the infants' medical records were missing were excluded. Patients were examined in dorsal decubitus, with the bladder empty. During the period studied, patients were identified as candidates for inclusion on the basis of having undergone fetal morphological ultrasonography. From this number, patients were recruited after application of the inclusion and exclusion criteria. Using the hospital records, all of the mothers were followed up to birth, and the newborn infants until confirmation or not of the intrauterine diagnosis of congenital anomaly.

The congenital anomalies were defined according to the 10th revision of the International Classification of Diseases. Data were collected by the researcher, using the patient records from the Fetal Medicine department, in addition to the records from obstetrics and pediatrics. The newborn infants' medical records were used to investigate their postnatal diagnoses.

External anomalies were confirmed on the basis of the clinical examination performed by the neonatologist. The diagnoses for all of the patients studied were confirmed or ratified retrospectively. Data were analyzed using Epi-Info , version 3. The Kappa index K 13 was used to demonstrate whether there was concordance between the prenatal ultrasound diagnosis and postnatal result.

The prenatal ultrasound diagnosis was validated by applying the Youden test Y Scores of 0. The prenatal and postnatal frequencies of fetal abnormalities having thus been established, broken down by organ and system, the sensitivity and specificity of the intrauterine ultrasound diagnoses were then calculated. During the period studied, high-risk expectant mothers were recruited.

Prenatal ultrasonography led to a diagnosis of congenital anomaly in The mothers' ages varied from 13 to 47 years, with a mean of Two hundred and fifty-seven The mean gestational age at birth was Morphological examinations were carried out according to routine practice at the institute between the 22nd and 24th weeks, between the 26th and 28th weeks and between the 32nd and 34th weeks of the pregnancy, with the number of times each patient was examined varying from one to three.

The majority of the expectant mothers underwent their first ultrasound examination between the 26th and 28th weeks. It was observed that fetuses had had a prenatal anatomic diagnosis and that of these were confirmed by postnatal examination. Therefore the fetal abnormality was confirmed in Breaking down the prenatal diagnoses of congenital anomalies by body system, Postnatal evidence was found of The anomaly that was least often confirmed postnatally was esophageal atresia The most common congenital anomalies of each system were analyzed.

The literature describes a large variation in the frequency of congenital anomalies diagnosed during the prenatal and postnatal periods 6,20, The high frequency of malformations observed in our study Furthermore, the exclusion criteria employed, such as births that did not take place at the I. Another retrospective study, which assessed the effectiveness of prenatal ultrasonography for detecting congenital anomalies, reported specificity of The divergent results in the studies mentioned above are primarily the result of the study populations and the degree of specialization of the ultrasound professionals.

While some of the studies are population-based, i. One issue worthy of note is that some of these studies were carried out in maternity units with a primary level of complexity, and make unsatisfactory reference to high-risk patients. Among these high-risk expectant mothers, morphological ultrasonography demonstrated good concordance with postnatal results.

  • From a total of patients with prenatal diagnoses of congenital anomalies, 42 were not confirmed after birth. According the European RADIUS study, ultrasonography should be performed at tertiary healthcare centers to allow for the best diagnostic investigation of fetal abnormalities, since Fetal Medicine specialists are better prepared to conduct fetal morphology studies than radiologists
