Prenatal sonographic diagnosis of Beck-with-Wiedemann syndrome in association with a single umbilical artery. In some cases, a free loop of the umbilical cord was viewed in cross-section and the vessels were counted. Unics diameter and resistance indices in normal fetuses with a single umbilical artery. The presence of a single umbilical artery SUA is associated with congenital fetal malformations and genetic anomalies.
Isolated single umbilical artery anomaly and the risk for congenital malformations: Any advice should be tailored to the particular pregnancy, taking into account other factors such as age, but we would not strongly recommend karyotyping in agreement with other authors.

The incidence of SUA in live born was 0. Fetuses with a SUA and abnormal Doppler veloci-metry have a significantly increased risk of growth retardation, complex malformations or an abnormal karyotype than those with a SUA but normal Doppler studies. The clinical significance of a single umbilical artery as an isolated finding of prenatal ultrasound. Umbilicl Obstet and Gynecol ; unixa Associated malformations and chromosomal abnormalities.
An increased risk of intrauterine growth retardation and the Doppler findings are controversial in the literature.

If other anomalies are detected, then the case should be managed according to the type and severity of the abnormalities. J Ultrasound Med, 19pp. Pulsatile umbilical venous flow and its clinical significance.
Ultrasound Obstet Gynecol, 3pp. Umbilical vein to artery ratio in fetuses with single umbilical artery.

In fetuses with SUA the entire blood flow to the placenta is transported through only one artery, producing a significant increase in the arterial diameter. Two cases and review of the literature. Volumetric umbilical artery blood flow: Fused umbilical arteries near placental cord insertion.

The first source of data produces a higher incidence of SUA, as well as more frequent association with structural and genetic abnormalities and perinatal mortality. Of these three live born, two presented associated malformations and in one case the malformation recognized antenatally was not confirmed in postnatal period. RESULTS During the study period there were fetuses delivered after 24 weeks gestation and 70 pregnancy interruption due to medical causes. Prenatal diagnosis of the two-vessel cord: Am J Med Genet, 43pp.
In fact, this is the best place to evaluate these vessels as they may fuse at the region of the umbilical cord insertion into the placenta. Ultrasonographic detection of single umbilical artery: Although this has not been true at all centers, a study by Abuhamad et al 26 found complex umgilical and chromosomal abnormalities exclusively when the left umbilical artery was absent.
