Single umbilical artery

Journal of Pharmacy and Bioallied Sciences, 2015
The umbilical cord usually contains two arteries and one vein. The vein carries the oxygenated blood from the placenta to the fetus. The arteries carry the deoxygenated blood and the waste products from the fetus to the placenta.

Vascular contraction of umbilical arteries of pregnant women with preeclampsia [PDF]

Revista Brasileira de Ginecologia e Obstetrícia
Objective: Potassium channels have an important role in the vascular adaptation during pregnancy and a reduction in the expression of adenosine triphosphate-sensitive potassium channels (Katp) has been linked to preeclampsia.

Isolated Single Umbilical Artery and Histomorphometric Changes of Umbilical Blood Vessels in Intrauterine Growth Retarded Foetus in Comparison to Normal Neonates

Journal of Pharmacy and Bioallied Sciences
Background: Three vessels—one vein and two arteries—allow the fetus and placenta to exchange waste, oxygen, and nutrients in the umbilical cord. Single umbilical artery (SUA), a congenital abnormality with one umbilical artery, can occur in some ...

Considering the Effects and Maternofoetal Implications of Vascular Disorders and the Umbilical Cord

Medicina, 2022
The umbilical cord is a critical anatomical structure connecting the placenta with the foetus, fulfilling multiple functions during pregnancy and hence influencing foetal development, programming and survival.

Fetal Sex and Fetal Environment Interact to Alter Diameter, Myogenic Tone, and Contractile Response to Thromboxane Analog in Rat Umbilical Cord Vessels

Frontiers in Physiology, 2021
Fetal growth needs adequate blood perfusion from both sides of the placenta, on the maternal side through the uterine vessels and on the fetal side through the umbilical cord.

Markers of Endothelial Dysfunction Are Attenuated by Resveratrol in Preeclampsia

Antioxidants, 2022
Preeclampsia (PE) is characterized by great endothelial dysfunction, decreased nitric oxide (NO) bioavailability, and higher levels of arginase activity. In the present study, we investigated the potential modulatory effects of trans-resveratrol (RSV) on

Ultrasound parameters of early pregnancy and Doppler indices of blood vessels in the placenta and umbilical cord throughout the pregnancy period in sheep

BMC Veterinary Research, 2022
Background Ultrasonography is one of the most important techniques that enable the detection and monitoring of pregnancy. One such study using this technique is the assessment of the hemodynamics of fetal and umbilical blood vessels.
