|May 1, 1986
Summary
Premature infants undergoing umbilical artery catheterization are at risk for developing aortic pseudoaneurysms. This case highlights multiple aortic pseudoaneurysms caused by Staphylococcus aureus sepsis, leading to severe complications and death.
Area of Science:
- Pediatric Cardiology
- Neonatalogy
- Infectious Diseases
Background:
- Umbilical artery catheterization is a common neonatal procedure.
- Sepsis can lead to serious vascular complications in neonates.
Observation:
- A premature infant developed three aortic pseudoaneurysms following umbilical artery catheterization and Staphylococcus aureus sepsis.
- The thoracic pseudoaneurysm resulted in fatal hemothorax.
- Abdominal aortic aneurysms caused renal hypoplasia and right leg ischemia.
Findings:
- This is the first reported case of multiple mycotic aortic aneurysms secondary to umbilical artery catheterization.
- Staphylococcus aureus septicemia was identified as the causative agent.
Implications:
- Highlights the potential for severe vascular complications from catheter-associated infections in neonates.
- Emphasizes the need for vigilance in monitoring for aortic pseudoaneurysms in at-risk infants.
- Underscores the critical role of infection control in neonatal intensive care units.
