A variety of methods, previously described ,25were employed by different sonographers to detect the presence of a single umbilical artery. A SUA in the second trimester of pregnancy has a high association with Trisomy 18, 13, 21 and other chromosomal defects, but all chromosomally abnormal fetuses had associated malformations detected umbilial ultrasound 5.
