INTRODUCTION: Congenital anomalies constitute an increasingly important for both obstetrics and neonatology for the chapter, genetics and biology; because of its relatively high frequency, the possibility of prenatal diagnosis and the tremendous progress being made to better understand the epidemiology, pathophysiology and especially the possibility of increasing early diagnosis and sometimes treat them. OBJECTIVES: To determine the predictive value of ultrasound diagnosis in detecting most common congenital anomalies in pregnant women between 11 and 14 weeks served in the Basic Unit of Primary Care Barranco (UBAP). Lima. January-March, 2013. DESIGN AND METHODS: This study is descriptive, cross-sectional, retrospective and quantitative nature. 113 medical records of pregnant patients were selected, information was collected in a data collection form, ordering the variables as age, parity and results of ultrasound examinations, and in some cases the result of amniocentesis (Test de Oro) for the subsequent comparison with ultrasound results. Data were passed to SPSS v.21 software; they were sorted and labeled variables for further analysis. RESULTS: The mean age of patients was 31.5 years; 50% have 31 years or more; the variance is 50.7; the average distances of age with respect to each average is 7.1; the most frequent ultrasound marker was found: 2.7% increased nuchal translucency and nasal bone absence of 0.9%. CONCLUSIONS: The evaluation of congenital anomalies by ultrasound should be considered a reliable method as early diagnosis because it has a higher predictive value 90%. The positive predictive value and negative predictive value of ultrasonography in contrast to cases confirmed by amniocentesis (gold standard) is 96% and 100% respectively; the sensitivity and specificity of ultrasonography is 80% and 100% respectively. KEYWORDS: conventional ultrasound, sensitivity, specificity, positive predictive value, negative predictive value, congenital anomaly.
