While some studies have shown a higher incidence of the condition among. While in some cases there are no complications in others there are risks involved.
Isolated single umbilical artery poses neonates at increased risk of long-term respiratory morbidity.
Single umbilical artery risks. Single umbilical artery and risk of congenital malformation. Population-based study in Norway SUA is associated strongly with gastrointestinal atresia or stenosis suggesting common developmental mechanisms. The increased risk of recurrence of SUA suggests that genetic andor persisting environmental factors influence the risk.
Single umbilical artery fetuses and neonates had a 677 times greater risk of congenital anomalies and 1535 times greater risk of chromosomal abnormalities. The most common congenital anomalies in chromosomally normal fetuses and neonates were genitourinary 648 followed by cardiovascular 625 and musculoskeletal 544. For isolated single umbilical artery placental abnormalities OR.
When only one artery is present in the umbilical cord the anomaly is called single umbilical artery. Presence of only one artery can affect the blood supply to the fetus. This is one of the reasons for increased risk of stillbirth miscarriages growth retardation and congenital defects.
Single umbilical artery is detected on sonography. What are the Risk Factors for Single Umbilical Artery. Predisposing Factors The risk factors for Single Umbilical Artery may include.
Chromosomal abnormalities such as trisomy 13 and trisomy 18. There is a controversy whether SUA occurs to a higher degree in twins. While some studies have shown a higher incidence of the condition among.
Single Umbilical Artery. Single umbilical artery SUA is the most common malformation of the umbilical cord. On its own SUA does not necessarily pose a risk to you or your child as an umbilical cord with just one artery is sufficient to support a pregnancy to term.
However SUA does increase your childs risk for certain birth defects. 79 Zeilen Single umbilical artery was associated with a congenital malformation in 11 of cases and. 11 0 to 14 1 weeks.
19 0 to 24 6 weeks. 30 0 to 37 6 weeks. Preterm birth - history.
Preterm birth - cervix. Single umbilical artery SUA is associated with congenital malformations in most organ systems but reported findings have not been consistent. Single umbilical artery SUA refers to a variation of umbilical cord anatomy in which there is only one umbilical artery.
It may be an isolated finding or associated with aneuploidy or other congenital anomalies. This topic will discuss issues related to prenatal. Isolated single umbilical artery poses neonates at increased risk of long-term respiratory morbidity.
Beharier O1 Sheiner E2 Sergienko R3 Landau D4 Szaingurten-Solodkin I2 Walfisch A2. Can a Single Umbilical Artery SUA Affect Your Baby. While in some cases there are no complications in others there are risks involved.

The absence of one umbilical artery which represents the most common anatomical abnormality of the umbilical cord is found in 0220 of deliveries. The pathogenesis of this condition known as single umbilical artery SUA is uncertain. Aplasia or atrophy of the missing vessel has been suggested in the etiology.
If the SUA is associated with other ultrasound findings or aneuploidy risk markers an increased risk of aneuploidy occurs of 9 range 0-26 and counseling regarding invasive diagnostic testing is indicated. If after thorough evaluation the SUA is felt to be isolated no additional prenatal testing is indicated. To determine whether fetal echocardiography is warranted in cases of single umbilical artery in a population at risk for aneuploidy.
All cases of fetal single umbilical artery identi-fied over a 2-year period were reviewed for other sonographically detected abnormalities fetal echocardiographic results and karyotype. Umbilical cord abnormalities are numerous ranging from false knots which have no clinical significance to vasa previa which often leads to fetal death. As prenatal ultrasonography becomes.
