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.

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 ...

Comparative study of umbilical cord cross-sectional area in foetuses with isolated single umbilical artery and normal umbilical artery

Journal of Obstetrics and Gynaecology, 2022
Single umbilical artery (SUA) is one of the most common prenatal diagnoses in cases of foetal abnormality. This prospective study evaluated 77 foetuses with isolated SUAs and 77 healthy foetuses, both at 22–39 gestational weeks.

Hypercoiling and Single Umbilical Artery Associated With Fetal Placental Malperfusion and Growth Restriction: A Case Report [PDF]

Clinical Case Reports
Hypercoiling of the umbilical cord can lead to fetal growth restriction and stillbirth because the cord is vulnerable to blood flow disturbances caused by external forces.

Umbilical artery thrombosis [PDF]

Medicine, 2019
Abstract Rationale: The umbilical cord is the way to exchange gas, supply nutrients, excrete metabolized. Thrombosis of the umbilical cord leads to fetal hypoxia, which jeopardizes fetal health and can cause fetal death. Umbilical vessel thrombosis, which is rarely reported, is difficult to detect prenatally.

Double umbilical artery converging into a single umbilical artery: A case report [PDF]

Medicine
Rationale: The normal structure and Doppler parameters of the umbilical cord are closely related to many diseases, including fetal infection, chromosomal abnormalities, hypoxia, and growth and development restrictions. We report a case of bilateral umbilical artery confluence resulting in the formation of a single umbilical ...

Novel ultralow positioning of the umbilical artery catheter: A prospective pilot study [PDF]

Journal of Ultrasonography
Thrombosis is a common complication of umbilical artery catheterization. The purpose of this study was to compare the novel ultralow umbilical artery catheter position (catheter tip at the junction of the umbilical and internal iliac arteries) versus the
