Single umbilical artery – marker for chromosomal abnormalities: report of two postnatal cases

V. Plaiasu, D. Ochiana, G. Motei, C. Cristea, F. Brezan, I. Anca


Abstract: Single umbilical artery (SUA) is one of the most common umbilical abnormalities. SUA is believed to be caused by agenesis of one of the umbilical arteries, atrophy of a previously normal artery, or presence of the original artery of the body stalk. SUA may occur either isolated or in conjecture with additional fetal and chromosomal abnormalities. Here we present two cases with prenatally diagnosed SUA, both associated with chromosomal abnormalities, and a short review of the literature. We emphasize the necessity of fetal karyotype assessment for patients with nonisolated SUA, those with abnormal genetic screening results and those with intrauterine growth restriction.
