RESUMO
The aim of the study was to determine the profile of congenital malformations [CM] among live births at Arvand hospital, in Ahwaz city. In this prospective study all of the neonates born at Arvand hospital in Ahwaz from 2004 to 2006 were registered. Stillbirths and those who died in a few hours after birth were excluded and finally 4660 newborns were enrolled. Of the 4660 live births 94 [20.2/1000] had at least a CM. The predominant systems involved were musculoskeletal [7.9/1000], followed by genitourinary [7.1/1000], central nervous [2.4 /1000], digestive [1.1/1000] and chromosomal anomalies [0.9/1000]. Although the frequency of malformations in the study was approximately similar to other investigations, if we include abortions, stillbirths and if we used screening tests and genetic studies, this rate was more than 20.1/1000
