Perinatal outcome of growth restricted fetuses with abnormal umbilical artery Doppler waveforms compared to growth restricted fetuses with normal umbilical artery Doppler waveforms at a tertiary referral hospital in urban Ethiopia.

PLoS ONE, 2020
BackgroundIntrauterine growth restriction is defined as a fetal weight below the 10th percentile for a given gestational age and can be identified using umbilical artery Doppler velocimetry which is a non-invasive technique.

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 ...

Ultrasound findings of distal umbilical artery calcification: A case report

Radiology Case Reports, 2022
Umbilical artery calcification is a rare finding with only a small number of cases reported on radiographs. To date, no cases have been described on ultrasound. Reported cases were limited to the horizontal segment of the medial umbilical ligament.

Expression of mRNA for phospholipase A(2), cyclooxygenases, and lipoxygenases in cultured human umbilical vascular endothelial and smooth muscle cells and in biopsies from umbilical arteries and veins [PDF]

, 1998
Arachidonic acid (AA) is released by phospholipase A(2) (PLA(2)) and then converted into vasoactive and inflammatory eicosanoids by cyclooxygenases (COX) and lipoxygenases (LOX).
