Effect of a Single Umbilical Artery on Fetal Middle Cerebral Artery Peak Systolic Velocity
- There is no direct evidence in the provided studies that specifically addresses the effect of a single umbilical artery on fetal middle cerebral artery peak systolic velocity 1, 2, 3, 4, 5.
- However, studies have shown that the presence of a single umbilical artery is associated with an increased risk of congenital abnormalities and adverse perinatal outcomes 1, 4, 5.
- One study found that umbilical venous pulsation, which can be related to a single umbilical artery, is associated with abnormal flow patterns in the umbilical artery and increased perinatal mortality 3.
- Another study found that fetuses with complete heart block had elevated umbilical artery and middle cerebral artery Doppler measurements, but the study did not specifically address the effect of a single umbilical artery on middle cerebral artery peak systolic velocity 2.
- The presence of a single umbilical artery has been associated with extra-CNS anomalies and chromosomal abnormalities in fetuses with central nervous system malformations 4.
- Overall, while there is no direct evidence on the effect of a single umbilical artery on fetal middle cerebral artery peak systolic velocity, the presence of a single umbilical artery is associated with increased risk of congenital abnormalities and adverse perinatal outcomes 1, 2, 3, 4, 5.
