We report a case of a single umbilical artery with various fetal anomalies, and a comparative study between prenatal ultrasonographic diagnosis and autopsy was done. The prenatal ultrasonographic diagnosis included, atrial septal defect (ASD), ventricular septal defect (VSD), mitral atresia or stenosis and a single great vessel. At autopsy, ASD, VSD, mitral atresia, overriding aorta and pulmonary atresia were evident. In case of other anomalies, the findings in the prenatal diagnosis and at autopsy were encephalocele, adrenal hypoplasia and a single umbilical artery. The ultrasonic detection of these anomalies is discussed and the limitations of this diagnostic method are given attention.
