AI Article Synopsis
- Umbilical artery aneurysm is a rare condition linked to serious fetal complications, such as anomalies and neonatal issues.
- A case report describes a fetus with a normal karyotype diagnosed with an umbilical artery aneurysm, leading to complications after delivery, but the newborn was ultimately discharged after treatment.
- Recommendations for managing this condition include intensive monitoring and early planned deliveries to improve survival chances, alongside counseling for parents about the associated risks.
Article Abstract
Background: Umbilical artery aneurysm is a rare and often lethal condition frequently associated with fetal anomalies, fetal demise, and neonatal complications.
Case: We report a case of umbilical artery aneurysm discovered at 21 weeks 2 days of gestation in a fetus of normal karyotype. Maternal hospitalization occurred at 28 weeks for antenatal testing, betamethasone administration, and monitoring for expansion of the aneurysm. Delivery of a live neonate by repeat cesarean delivery was performed at 32 weeks 2 days. Pathology confirmed a 3-vessel cord with an umbilical artery aneurysm. Neonatal course was complicated by respiratory distress of the newborn, hyperbilirubinemia, anemia, difficulty feeding, and cardiac defects. The newborn was discharged from the neonatal intensive care unit on day of life 19.
Conclusions: Umbilical artery aneurysm is highly associated with fetal complications including trisomy 18, single umbilical artery, cardiac anomalies, and intrauterine fetal demise. A normal karyotype, antenatal monitoring, and early delivery have been suggested to impact the likeliness of survival. Antenatal management strategies include consideration of nonstress testing 3 times daily, serial ultrasound assessments, testing to identify intrauterine growth restriction, and delivery by planned cesarean delivery between 32 and 34 weeks. We recommend that patients be counseled on the high risks associated with umbilical artery aneurysm and be included in discussions regarding antenatal management and delivery planning.

Removal of microcatheter entrapped in the middle cerebral artery in a neonate via common carotid arteriotomy.

A 2-day-old neonate was referred to the vascular surgery service owing to concerns of limb perfusion after entrapment of a microcatheter in the middle cerebral artery. The catheter was inserted via the umbilical artery to treat a vein of Galen arteriovenous malformation. This catheter inadvertently became entrapped owing to device failure, was cut at the insertion site, and left in situ for 3 months.

Objective: The objective of this study was to conduct a longitudinal assessment of inter-twin growth and Doppler discordance, to identify possible distinct patterns, and to investigate the predictive value of longitudinal discordance patterns for adverse perinatal outcomes in twin pregnancies.
Methods: This retrospective cohort study included twin pregnancies followed and delivered at a tertiary University Hospital in London (UK), between 2010 and 2023. We included pregnancies with at least three ultrasound assessments after 18 weeks and delivery after 34 weeks' gestation.

Introduction: Fetal scalp blood sampling (FSBS) can be used as an adjunctive test, in the presence of a pathological intrapartum fetal heart rate trace, to provide evidence of fetal acidaemia. The role of FSBS remains controversial, this study evaluates the diagnostic accuracy of FSBS at determining various adverse neonatal outcomes.
Method: A retrospective cohort analysis of FSBS undertaken < 1 h from birth in a single UK centre in 2016 and 2017.

Background: Preclinical studies have documented the role of alpha-adrenergic agonists in myometrial contraction. Phenylephrine is frequently used to prevent and treat post-spinal hypotension during cesarean delivery. We hypothesized phenylephrine would reduce postpartum blood loss due to alpha-1 receptor-mediated uterine and vascular smooth muscle contraction.
