Normal umbilical artery doppler values in 18-22 week old fetuses with single umbilical artery. [PDF]

Sci Rep, 2023
AbstractUmbilical cord with a single umbilical artery (SUA) can carry twice the blood volume of a three-vessel cord (TVC). So, the normal hemodynamics of the fetuses with SUA was different from those with TVC. Furthermore, structural abnormalities, fetal aneuploidy, and intrinsic growth retardation may be associated with the presence of a SUA. In order

Umbilical artery Doppler velocimetry in fetuses with a single umbilical artery [PDF]

Obstetrics & Gynecology, 1997
Doppler waveform analysis of the umbilical artery is an important tool for the evaluation of high-risk pregnancies. Yet, available data are based on normal values from three-vessel umbilical cords. Our purpose was to evaluate the value of umbilical artery Doppler velocimetry in fetuses with a single umbilical artery.One hundred thirteen consecutive ...

ALK1 controls hepatic vessel formation, angiodiversity, and angiocrine functions in hereditary hemorrhagic telangiectasia of the liver

Hepatology, EarlyView., 2022
Hepatic endothelial Alk1 signaling protects from development of vascular malformations while maintaining organ‐specific endothelial differentiation and angiocrine portmanteau of the names Wingless and Int‐1 signaling. Abstract Background and Aims In hereditary hemorrhagic telangiectasia (HHT), severe liver vascular malformations are associated with ...

Sex differences in umbilical artery Doppler indices: a longitudinal study. [PDF]

Biol Sex Differ, 2018
Sexual dimorphism in placental size and function has been described. Whether this influences the clinically important umbilical artery (UA) waveform remains controversial, although a few cross-sectional studies have shown sex differences in UA pulsatility index (PI).

Successful amnioinfusion for severe fetal growth restriction with umbilical cord complications: two case reports

Journal of Medical Case Reports, 2021
Background There is no established treatment for fetal growth restriction during pregnancy. We report two cases that represent an example of an amnioinfusion-based management strategy for severe fetal growth restriction with umbilical cord complications.

Study of abnormal umbilical artery doppler and neonatal outcome

Asian Journal of Medical Sciences, 2019
Background: Doppler provides assessment of uteroplacental and fetoplacental circulation during pregnancy. It is a sensitive tool in early detection of fetal compromise and allows needful intervention. Aims and Objective: To study the role of umbilical

Doppler ultrasound hemodynamic assessment in preeclampsia

Medical Journal of Babylon, 2018
Background: Preeclampsia (PE) is the main factor in maternal mortality across the world, affecting 5%–8% of pregnant women. The impairment in placental perfusion due to vascular abnormalities leads to clinical presentations and is detectable by Doppler ...

Fetal acidosis and Doppler velocimetry of the umbilical arteries in labor [PDF]

Ultrasound in Obstetrics & Gynecology, 1993
AbstractThe objective of the study was to determine whether Doppler velocimetry indices of the fetal umbilical arteries change with the development of acidosis during labor. Repeated Doppler velocimetry was performed in selected patients with high‐risk labors for the purpose of evaluating whether this might be a useful test of fetal well‐being in labor.
