Overview
The abnormalities that may be associated with Down syndrome on ultrasound include intrauterine growth restriction, mild cerebral ventriculomegaly, choroid plexus cysts, increased nuchal fold thickness,cystic hygromas, echogenic intracardiac foci, congenital heart defects, duodenal atresia (“double-bubble sign”) increased intestinal echogenicity, renal pelvis dilation, shortened humerus and femur, increased iliac wing angle, incurving (clinodactyly) and hypoplasia of the fifth finger, increased space between first and second toes and the two-vessel umbilical cord. There are no echocardiographic findings associated with Down syndrome however 40-60 percent of patients with Down syndrome suffer from congenital heart defects the most common being atrial septal defect, atrioventricular septal defect, ventricular septal defect, and patent ductus arteriosus. The echocardiographic findings in Down syndrome are of the aforementioned underlying congenital heart defects.
