GOMEZ-RUIZ, Juan Camilo; FERNANDEZ, Nicolás; PAEZ, Paola  and  ZARANTE. Using prenatal ultrasound for detecting congenital anomalies in 12.760 newborn babies from 20042005 in 3 hospitals in Bogotá, Colombia. Rev Colomb Obstet Ginecol [online]. 2007, vol.58, n.3, pp.194-201. ISSN 0034-7434.

Objective using ultrasound as diagnostic method for determining the frequency of pre-natally diagnosed congenital abnormalities. Methods: a study of cases and controls using Latin-American Collaborative Study of Congenital Malformations (ECLAMC) methodology. All newborn children from 3 hospitals in Bogotá were assessed during 2004 and 2005. Results: 12.760 newborn were reported. 382 of the newborns had congenital abnormalities (2.99%); however, only complete information was obtained for 287 of the cases (75.13%). An average of 3,47 sonographic evaluations were made for the cases and 3.19 for the controls (p<0.05). The cases had lower gestational age (37.59 cf 38.29 weeks) (p<0.01), lower birth weight (2,841.9 cf 3,022.67 grs) (p<0.01) and height (48.3 cm cf 49.34) (p<0.01) than the control group. 151 congenital abnormalities were diagnosed using obstetric ultrasound (52.6%); however, just 49 of them (32.5%) were detected using this tool. Conclusions: ultrasound detection rate in the 3 hospitals was lower compared to data from other studies. There is thus a need for better quality and technology to improve major congenital abnormality detection rates.
