The prenatal diagnosis of ventral abdominal wall defects

Abstract

Ventral abdominal defects are frequently diagnosed by prenatal ultrasonography. This review of 47 infants with ventral defects was designed to determine the effect of prenatal diagnosis on neonatal outcome. All nine infants with prenatal diagnosis were delivered by cesarean section at tertiary level hospitals. Only 13 (34%) of 38 infants with unsuspected defects were delivered by cesarean section and 15 (39%) were delivered at tertiary level hospitals. There was no difference in mortality between infants with prenatal diagnosis (44%) and those with unsuspected defects (37%). Increased mortality correlated with the presence of other major anomalies (79% mortality), with birth weight less than 1500 gm (80%), and with omphaloceles (65%). We conclude that infants with other associated defects or with birth weight less than 1500 gm have poor outcomes and cesarean section may not be justifiable. However, in larger infants without other anomalies, prenatal diagnosis was followed by cesarean section and a good prognosis.
