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 ...

Journal of Lipid Research, 1997 Polyunsaturated fatty acids (PUFA) like arachidonic (C20:4) and docosahexaenoic (C22:6) acids are essential for harmonious fetal development. This study evaluates, at near term, the distributions of free fatty acids (FFA) and their fetal carrier protein,

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).

A Rare Complex Case of Congenital Umbilical Arteriovenous Malformation and Review of Literature
American Journal of Perinatology Reports, 2016 Introduction Congenital umbilical arteriovenous malformations (AVMs) are extremely rare. We present the first case of congenital umbilical AVM with feeding arteries originating not only from abdominal but also from the mammary arteries. Case

Current Medicine Research and Practice, 2021 Umbilical cord has two arteries and one vein. The absence of one artery is referred to as single umbilical artery which could be because of primary agenesis of umbilical artery or atrophy or secondary atresia of the previously normally developed ...

Umbilical artery pseudoaneurysm
Journal of the Belgian Society of Radiology, 2015 A 5-week-old baby boy was referred to ultrasonography because of a discharging umbilical granuloma (UG) not responding to silver nitrate applications. He had no medical history, birth occurred without complications. Ultrasonography (US) found an anechoic 5 mm umbilical mass (Fig. A). Doppler color (Fig.

Umbilical vein to artery ratio in fetuses with single umbilical artery [PDF]
Ultrasound in Obstetrics and Gynecology, 1996 In fetuses with single umbilical artery (SUA) the entire blood flow to the placenta is transported through only one umbilical artery, resulting in a compensatory increase of the arterial diameter. In order to establish whether umbilical vessel size could be used as an additional ultrasonographic criterion for prenatal diagnosis of SUA, we measured ...

Umbilical artery perforation: a potentially life-threatening complication of umbilical artery catheterisation [PDF]
BMJ Case Reports, 2017 Umbilical artery catheterisation is frequently performed in preterm or critically ill newborn infants for invasive monitoring of blood pressure and blood sampling for laboratory tests. It is associated with well-known complications like catheter-related infections, thromboembolic events and aneurysmal formation of the aorta.

PLoS ONE, 2020 Human fetal thermoregulation, maternal-fetal heat exchange, and the role of the umbilical cord in these processes are not well understood. Ethical and technical limitations have restricted current knowledge to animal studies, that do not reflect human ...
